#NPC List Summary

#5.1 · Mumyo(無明) — Sealing Stone Avatar

#Overview

Name: Mumyo(無明). "That which is not light." A will-body of one of the 3 axes of the core Enmadoji Seal.

Role: lord-grade antagonist. Boss of the final battle in Act 3.

Personality: a tired public official. Someone who has done the sealing stone's work for 100 years. There is no malice. He is simply faithful to his duty.

Physical Appearance: 180cm tall. Japanese-style official dress carved from black stone. Noh mask. Eyes are purple flames. In Phase 2, the mask breaks and his face becomes the landscape of the Avici wasteland.

#Narrative Background

Mumyo was built to dwell in one of the sealing stone's 3 axes during the Enmadoji sealing rite 100 years ago. According to the core setting, Enmadoji is the massive sealing system that maintains the boundary between hell and the human realm, and one axis of that system lay beneath this domain.

Mumyo is the one who held the sealing stone in place whenever it shook. The reason this domain fell 100 years ago is that the sealing stone had already begun to shake, and Mumyo held that shaking by pulling down "the entire domain." A kind of excessive loyalty.

#Lines

#First Meeting (Scene 3.5)

"...You came. Someone comes in the 100th year. This time, it is you."

"I am the will of this stone. This stone has held your domain for 100 years. That was my work. Today, you are trying to end my work."

#Lines During the Conversation Window

"...If I abandon my work, there is one more path. But that is my choice, not yours. Today, I will receive only your choice."

#Start of Phase 2

"...You have come this far. From here onward, I grow weaker. But growing weaker does not mean I wish to die."

"My name is Mumyo. But the moment you decide what name you will call me, I become — something else."

#Final Lines by Ending

Ending A (Resealing): the moment the seal closes onto him.

"...So the order is to sleep again. Then I will sleep. When I next wake, I will wake a little more quietly."

Ending B (Pact): the moment he accepts the pact.

"...Accepted. From today onward, I become the boundary of your domain. I have worked for 100 years, so working another 100 years will not be difficult. But remember my name."

Ending C (Transformation): the moment he accepts the Transformation PC.

"...I have received your cost. You now stand beside the door with me. Welcome. You will not be lonely. For about 100 years... I can tell you stories too."

#Combat Statistics

For detailed stats, see Chapter 5 Yoma Bestiary — Residents of Avici. Summary:

• Lord-Grade: yes (campaign final boss).
• Dan Conversion: roughly 11th dan (a level a party of 9th-dan PCs can barely defeat when using Renown Titles).
• Core Attacks: "Nameless Fist," "Purple Fire," "Name Bestowal," and "Stone Regeneration."
• Phase Transition: becomes the awakened body when Phase 1 Wounds reach 0, or when the resealing rite succeeds 3 times. On phase transition, appearance and patterns change.

#GM Operating Guidelines

#Operating Principle 1 — Not a Villain

Mumyo does not hate the PCs. He is only doing his job. The GM should put a public official's exhaustion into his lines. Human emotions such as laughter or anger should appear only faintly.

#Operating Principle 2 — Preserve Dignity

Mumyo is a being who worked for 100 years. Treat him not as a "big boss," but as a high-ranking public official. Even during combat, preserve his formality.

#Operating Principle 3 — Possibility of Giving Up

The hidden "giving up" route in Act 3 Scene 3.5. If players attempt sufficiently strong negotiation, the GM may allow this route. Do not hint at it.

#Operating Principle 4 — Promise to Remember the Name

Mumyo fears that his name will be forgotten. In the Pact and Transformation endings, his demand to "remember my name" is sincere. The PCs accepting that demand is the emotional core of the pact.

---

#5.2 · Voice of Enmadoji — Higher Being

#Overview

Name: Voice of Enmadoji (the Sound of Enmadoji, 閻魔堂寺). No specific name. The higher will of the core Enmadoji system.

Role: higher being. Cannot be faced directly. Communicates only through indirect signs, prophecies, and dreams.

Personality: vast. Not emotional. From a human perspective, it may seem cold, but it follows its own logic.

Physical Appearance: none. It reveals itself to the PCs through one of several indirect expressions:

• Huge Eyes: hundreds of eyes floating in the sky. A motif of core Enmadoji iconography.
• Bell Sound: a bell at the domain shrine ringing by itself.
• Dream Voice: the voice of an old man heard by a sleeping PC.
• Landscape Distortion: at a specific moment, the domain's landscape twists slightly.

#Narrative Background

Enmadoji is the massive sealing system that maintains the boundary between hell and the human realm in the main-world. Mumyo is one of its axes. The Voice of Enmadoji is the will of that system itself.

In this supplement, the Voice of Enmadoji does not speak directly with player characters. It does, however, convey hints, blessings, and warnings at specific moments.

#Indirect Contact Moments (Limited to 3 Times in the Chapter)

#1st Time — After the First Meeting Before the Door in Act 1

On the road back to the domain, a short voice reaches one person's ear:

"...I heard well. Your standing before the door. I am still watching you."

(Who hears it is at the GM's discretion. Prioritize a protagonist-grade PC, or an onmyoji/shugenja PC.)

#2nd Time — After the Memorial Rite in Act 2

On the night of the memorial rite, one sentence enters every PC's dream:

"...I permit all three paths. Choose for yourselves. My will is that your will becomes my will."

This sentence is Enmadoji's approval that all endings are legitimate.

#3rd Time — During the Act 3 Battle

The moment Mumyo shifts into the awakened body, the sky rings with three bells. Every PC gains a +1 temporary bonus to checks (1 round). This is not a signal that Enmadoji is on the PCs' side, but a mark of neutral observation.

#4th Time (Hidden) — During the Transformation Ending

The moment the Transformation PC completes the vow, one sentence enters the Transformation PC's consciousness directly:

"...Well done. I will listen again after 100 years."

This is Enmadoji's only human expression.

#GM Operating Guidelines

#Operating Principle 1 — Rarity

The Voice of Enmadoji appears only 3~4 times in this chapter. Do not overuse it. Every time it is heard, players should feel a chill.

#Operating Principle 2 — Block Attempts at Conversation

If a player declares that they will "speak to Enmadoji," the GM blocks it. There is no answer. But block it not with an empty refusal, but with a change in the landscape, such as the domain sky briefly darkening.

#Operating Principle 3 — Basic Principle of a Higher Being

Enmadoji does not judge by human morality. It neither praises the PCs' "right choice" nor rebukes a "wrong choice." It merely observes and permits.

#5.3 · Mirror-Surface Miko — Return Ending Helper

#Overview

Name: Miyabi(雅). Called the Mirror-Surface Miko. An apostle of the core Enmadoji system.

Role: helper for the Return Ending. Assists officiation during the seal reinstallation rite.

Personality: quiet and firm. Appears to be in her late 10s (actual age unknown). She says little, but every word is exact.

Physical Appearance: 155cm tall. White miko attire. Long black hair. Carries an oil-paper umbrella. Her face changes expression as little as a mask. But there is warmth in her eyes.

#Appearance Condition

Appears only when the Return Ending route is progressing. She appears in front of the shrine during Act 2 Track 1 (onmyoji final preparation).

#Narrative Role

Miyabi is a rite officiation assistant dispatched by Enmadoji. She handles sutra transmission, procedure supervision, and final Barrier adjustment so that the Renown Title declarant's resealing rite can succeed.

Miyabi is not on the PCs' side. She is on Enmadoji's side. However, because Enmadoji's will is to "permit all three endings," she ends up helping the Return Ending.

#Appearance Scenes

#First Appearance (Act 2 Track 1)

Immediately after Gensho tells the PCs that "the Renown Title declarant must master the sutra," Miyabi stands in front of the shrine. Holding an umbrella. Silent.

"...I came because old Hoshino Gensho called. I am Miyabi. I have come to assist the sutra officiation."

#Sutra Transmission Scene

Miyabi hands the resealing sutra scroll to the Renown Title declarant or the PC in charge of mastering the sutra, then explains it line by line. This process takes 1~2 hours during Act 2.

#Act 3 Accompaniment

Miyabi does not accompany the Act 3 expedition. She remains at the shrine and indirectly supports the Barrier.

#Act 4 Resealing Rite

When entering Ending A, she gives remote support from the shrine. The moment the chant rings out, Miyabi's umbrella opens halfway, and a strand of purple smoke rises from the shrine and reaches the sealing stone. This connection is the chant's middle amplification.

#Act 4 Epilogue

After resealing is complete, Miyabi gives a short bow and disappears. She does not exchange words with the PCs. She leaves no trace in the domain.

#Hidden Lines (if a PC asks)

Q: Who are you?

"I am Miyabi. Miko of the Mirror Surface. Beyond that — I do not know myself."

Q: Did Enmadoji send you?

"...Yes. That is so."

Q: Do you come for the other endings too?

"...No. I stand only on the path of Return. Others stand on the other paths."

#Combat Statistics

Miyabi does not fight. She has self-defense ability (roughly 6th dan), but does not take hostile action.

#GM Operating Guidelines

#Operating Principle 1 — Not Friendly

Miyabi is not the PCs' friend. She is a public official. Avoid friendly conversation and maintain only an official relationship.

#Operating Principle 2 — Suppressed Emotion

There is only one moment when Miyabi shows emotion: a very brief smile immediately after resealing is complete. Otherwise, she is expressionless.

#Operating Principle 3 — Swift Exit

After the ending is complete, Miyabi quietly disappears. There is almost no later story for Miyabi in the epilogue (she returns to the Enmadoji system).

#5.4 · Old Monk of Black Darkness — Settlement Ending Helper

#Overview

Name: Monk Genjo(玄照). Called the Old Monk of Black Darkness. A native Buddhist practitioner of the Spirit Realm.

Role: helper for the Settlement Ending. Drafts the Spirit Realm pact text, supervises negotiation with Mumyo, and officiates Akihisa's renaming rite.

Personality: relaxed and humorous. A monk in his 70s. Talkative and often joking. But in decisive moments, he is solemn.

Physical Appearance: 170cm tall. Gaunt build. Half-shaved head (half of his gray hair remains). In his hand is a metal shakujou staff; the bells attached to it announce his arrival. Black monk's robes. Deep wrinkles on his face, but mischief in his eyes.

#Appearance Condition

Appears only when the Settlement Ending route is progressing. He suddenly appears in Akihisa's office during Act 2 Track 2 (domain delegation).

Important: his name overlaps with Hoshino Gensho (玄照 vs Gensho). This is intentional: a relationship as a mirror image of the Spirit Realm. The GM should present the moment when players discover this overlap.

#Narrative Background

The Old Monk of Black Darkness is a Buddhist practitioner native to the Spirit Realm. He is not a monk from the main-world, but a practitioner inside the Spirit Realm system, someone who has researched the possibility of Spirit Realm settlement. He has watched this land drift since 100 years ago.

The overlap with old Hoshino Gensho is not coincidence. It is also possible to interpret the two Genshos as two sides of the same being (whether to activate this interpretation is at the GM's discretion).

#Appearance Scenes

#First Appearance (Act 2 Track 2)

On the night Akihisa is writing the Settlement Ending testament, the bells of a shakujou sound at the office window. When the window opens, the Old Monk of Black Darkness is standing there.

"...May I come in? I was already half inside without being asked, so this is a formality."

#Assisting Pact Text Drafting

The old monk drafts the Spirit Realm pact text together with the PCs. This process takes 1~2 hours during Act 2. The old monk provides a modifier for Negotiation + Wisdom checks at Target Number 11~13.

"...The Spirit Realm uses many words. Write the document briefly. But make the heart clear. 'We settle,' 'we do not return,' 'we change the name' — if those three are present, that is enough."

#Act 3 Accompaniment

The old monk accompanies the Act 3 expedition. When facing the sealing stone, he supports from the PC rear.

Old monk combat support:

• Sutra Chorus: all PCs get +1 to checks (per round).
• Shakujou Bells: nullifies Mumyo's "Name Bestowal" attack 1 time.
• Barrier Adjustment: eases Avici silence (Target Number for conversation checks -2).

#Act 4 Renaming Rite

When entering Ending B, he officiates Akihisa's renaming rite. Holding the mirror-surface mirror, he stands before Akihisa and calls out the new name.

"...Kamijo Akihisa. Today, we erase your name. Your new name is — (Akikami, or another). Receive that name as a member of the Spirit Realm."

#Act 4 Epilogue

After the Settlement Ending, the old monk settles in the domain. He builds a small hermitage beside the shrine and stays long term. He gets along well with residents. After 20~30 years, he naturally enters nirvana.

#Meeting Hoshino Gensho (Settlement Ending + Gensho Survival Route)

A scene with both Genshos in the same room at once. The old monk laughs and says one line:

"...I am Genjo(玄照). You are Gensho(玄照). Same characters, different reading, is it not? ...Perhaps we have long been two sides of one person."

Hoshino Gensho closes his eyes and nods. Without a word.

#Combat Statistics

The old monk is a roughly 6th~7th-dan monk. His combat participation is rear support only. Low attack power, moderate defense, Barrier, and support.

#GM Operating Guidelines

#Operating Principle 1 — Balance Humor and Dignity

The old monk jokes often, but in rite scenes he is polite and dignified. Let players feel that "this character is funny," while still seeing him as someone they can rely on in decisive moments.

#Operating Principle 2 — Contrast of the Two Genshos

If Hoshino Gensho is "the weakened main-world onmyoji," the Old Monk of Black Darkness is "the healthy Spirit Realm monk." The contrast between the two is the emotional structure of the Settlement Ending.

#Operating Principle 3 — Symbol of Settlement in the Domain

The old monk settling in the domain is a success marker for the Settlement Ending. When his hermitage is built in the domain, it signals that the Settlement Ending is complete.

#5.5 · Rinrin the Nine-Tailed Fox — Transformation Ending Helper

#Overview

Name: Rinrin(鈴鈴). Nine-tailed fox(九尾狐). True name unknown.

Role: helper for the Transformation Ending. Supervises the Transformation rite and accompanies the Transformation PC's "abdication from humanity."

Personality: playful and fickle. A yokai who has lived for centuries. But in decisive moments, she is startlingly serious.

Physical Appearance: appears as a woman in her early 20s. 160cm tall. Layered kimono (the color changes every day). Behind her head sway 9 translucent tails. Usually she hides the tails, but they appear when emotion rises. She has fox ears.

#Appearance Condition

Appears when the Transformation Ending route is possible. There must be a PC who meets the Transformation conditions. She sometimes appears from the middle of Act 1 and appears in parallel with Act 2 Track 3 (romance) or Track 5 (records).

#Narrative Background

Rinrin is a yokai native to the Spirit Realm. By core standards, she is a powerful being equivalent to a 7th~8th-dan yoma. A nine-tailed fox who has lived for centuries, she has witnessed several drifters who underwent Transformation in the past.

Rinrin herself once reached the point "just before Transformation." But at the final moment, she gave up and remained a yokai. In this capacity as an unfinished transformer, she helps the current Transformation candidate.

#Appearance Scenes

#First Appearance (Act 1 Wasteland)

While the PCs walk through the Avici wasteland, they hear a fox cry from far away. When one PC looks back, a small white fox is sitting there. If they try to speak to it, it disappears.

#Second Appearance (Act 2 Track)

At the forest edge behind the domain. When a PC with confirmed Compassion(慈) in the Three Ways and Six Hearts is alone, Rinrin appears in human form.

"...Ah, we finally meet. You're the one, right? The kid who's going to be my friend?"

Rinrin begins talking without reserve. She does not talk at length, but sometimes says something serious:

"...Do you know what Transformation is? I tried it. I tried, then gave up. That's why I look like this now. But you — I think you'll do it. What I couldn't."

#Whether She Accompanies Act 3

Rinrin does not accompany the Act 3 expedition. However, she occasionally appears in the Transformation PC's dreams or intuition.

#Supervising the Transformation Rite

The moment the Transformation PC vows before the sealing stone, Rinrin appears in a dream space. Only the Transformation PC sees her. Other PCs do not sense her.

Rinrin's final line:

"...Now it starts. It's all right. It won't hurt. ...No, that's a lie. It will hurt just a little. But it'll be all right. I'll watch beside you. You won't do it alone."

Rinrin takes the Transformation PC's hand. She wraps the wrist where blood flows. Until the moment the hand turns transparent.

#Act 4 Epilogue

Companion of the Transformation PC: Rinrin spends centuries with the Transformation PC in the Spirit Realm. Even if this is not a romance route, they are close companions. She keeps the Transformation PC from being alone.

On the Romance Route: the relationship between the Transformation PC and Rinrin develops into romance. They remain as one of the guardian couples of the Spirit Realm.

If There Is No Transformation PC (Transformation Ending Not Run): Rinrin disappears from the domain. Without regret.

#Rinrin's Hidden Story (on Deep Conversation)

If a PC becomes close enough to Rinrin (3 or more cumulative Negotiation attempts), Rinrin may reveal her past:

"...I tried to transform 200 years ago. Back then, my level was... maybe about 9th dan, like you are now. But... at the last moment, I ran away. I still think about that moment. If I'd kept standing there, the me now would have been — like you."

"That's why I'm helping you. You doing what I couldn't do... frees my resentment too."

#Combat Statistics

Rinrin is originally a 7th~8th-dan nine-tailed fox. However, in this chapter, she does not take part in combat. Instead, she supports the Transformation rite, conversation, and companionship.

If the GM needs combat stats for Rinrin, see "Rinrin Combat-Form Variation" in the Yoma Bestiary.

#GM Operating Guidelines

#Operating Principle 1 — Mask of Lightness

Rinrin hides her true feelings behind mischief. Let players discover the depth behind her light lines.

#Operating Principle 2 — Dignity of Transformation

When Rinrin speaks to the Transformation PC, she speaks as a friend, but she guides them so they do not make the decision lightly. Rinrin herself knows the weight of Transformation.

#Operating Principle 3 — Guard Against Excess Romance

Rinrin does not automatically become a romance partner. Proceed in that direction only when the player clearly wants romance. By default, her position is "very close friend."

#Operating Principle 4 — The Past of 200 Years

Rinrin's hidden story should be brought out carefully by the GM. If she reveals it too easily, it loses weight. Reveal it only in limited form to PCs with enough cumulative Negotiation.

---

#Ending Helper Comparison Summary

The three helpers embody the emotional theme of the three endings:

• Miyabi: the formality and solemnity of sacrifice in the Return Ending.
• Old Monk Genjo: the peace and adaptation to everyday life in the Settlement Ending.
• Rinrin: the paradox of solitude and companionship in the Transformation Ending.

---

#Overall NPC Operating Principles

#Principle 1 — Helpers Are Not the Center

The three helpers exist to support the PCs' story. If players focus too much on a helper, the GM gently turns attention back to the PC's own decision.

#Principle 2 — Preserve Enmadoji's Indirectness

The Voice of Enmadoji is not a conversation partner. Even if the PCs try to negotiate with Enmadoji, they cannot. This distance gives the higher being its weight.

#Principle 3 — Mumyo's "Pitiful Public Official" Frame

Do not run Mumyo as a generic villain. The pathos of a public official is his emotional core.

#Principle 4 — Helpers' Exits

In the epilogue, the three helpers exit in their own ways (disappearing, settling, accompanying). The GM handles these exits cleanly. Unless players ask, do not drag out their later stories.

"...Five faces. Five paths. Five stories. Of them, the ones you meet are only the ones you chose." — Opening text of the Chapter 5 NPC index.
