Yomi no Sho — Chronicle of the Underworld

Welcome, Wanderer

Yomi no Sho (黄泉の書, “Book of the Underworld”) is a dark-anime idle RPG set in the shadowed afterlife of Japanese myth. You play a freshly-dead soul who washes up on the banks of Yomi Town with no coin, no memories, and only a borrowed blade to your name. From there you venture outward into eight progressively darker zones, slaying yokai, hoarding loot, and uncovering the slow corruption at the heart of the underworld.

This wiki is a player guide — written by players, for players. It covers every class, every zone, every enemy, every item, every NPC, every quest, and every mechanic in the game. It is intentionally spoiler-light on plot (the story is told through NPC dialogue, not cutscenes) but thorough on numbers, because the combat math is what determines whether you survive the deeper zones.

Getting Started

Account creation, character creation, your first hour in Yomi Town, and the basic idle loop.

Classes

The four playable classes — Samurai, Onmyoji, Shinobi, Sohei — with base stats, growth, signature skills, and build advice.

Zones

The safe hub of Yomi Town plus eight combat zones, with level ranges, enemy types, and what loot drops where.

Bestiary

Every enemy archetype in the game, their stats, and the boss mechanic that turns every 10th stage into a fight for your life.

Items

All 42 equipment pieces across 8 slots and 4 rarities, plus drop rates and where to find them.

NPCs

The seven NPCs you’ll meet across Yomi — merchants, healers, guards, quest-givers, and one storyteller who knows too much.

Quests

The seven-chapter quest chain that walks you from Yomi Town to the Throne of Fire — objectives, prerequisites, rewards.

Mechanics

The combat formula, the XP curve, stat allocation, skill cooldowns, and the idle loop — explained in plain terms.

Social

Friends, PvP duels with gold bets, item trading, and the local/global chat split (global costs 10 gold per message).

Reference

Glossary, FAQ, and patch notes.

A note on the dark

Yomi is not a friendly place. The first combat zone (Withered Bamboo Grove) is gentle, but by zone 3 (Crimson Torii Path) you will be dying to bosses if you haven’t upgraded your gear. By zone 7 (Throne of Kagutsuchi) you will be dying to trash mobs if you haven’t allocated your stats wisely. The wiki documents the math so you can plan ahead, but the game itself rewards caution and preparation — read the zone pages before you travel into a new one.
