1. Chapter Overview

Attribute Value
Chapter 1 — "The Dark Realm Awakens"
Estimated Time 1.5 – 2 hours
Difficulty Easy (tutorial chapter)
Setting Burning village & surrounding forest path To be verified at launch
Story Summary The protagonist witnesses the Genma's first major assault, escapes the burning village, and meets an Oni Clan ally who teaches the Onimaru blade's power.
Key Unlocks Onimaru (starting weapon), basic parry, basic Issen, first skill tree node access
Recommended Level 1 – 3 (level-up naturally via training and Forest Path farming)

Chapter 1 introduces every core system you'll use for the entire game: basic sword combos, parry timing, Issen counter-attacks, soul absorption, and skill tree navigation. Expect a linear path with two optional side branches (the hidden cave and the Forest Path ambush) that reward the curious with bonus items and souls.

2. Main Objectives

  1. Survive the village assault — The opening cutscene. The Oni Clan ally directs you out of the burning settlement.
  2. Escape through the burning streets — Avoid red-glowing fire hazards and use dodge (Circle/B) to slip past falling debris.
  3. Encounter the Oni Clan stranger — The ally intercepts you mid-escape and teaches the Onimaru blade's power.
  4. Learn basic combat (training sequence with wooden dummies) — Optional but recommended. Hitting 5 wooden dummies unlocks your first skill tree node.
  5. Practice your first parry against a Genma Brute — A single-enemy tutorial encounter. Press L1/LB just before the attack lands.
  6. Reach the village outskirts shrine — Save point, soul farming location, and the Onimaru handoff.
  7. Face the Chapter 1 boss: Marcellus — Arena unlocks after a short cutscene at the shrine. Dialogue flags To be verified at launch
Completion Tip

Don't skip the training dummies. They look optional but hitting all 5 is the only way to unlock the first skill tree node and start earning passive stat bonuses that carry into Chapter 2.

3. Walkthrough

Section 1 — Village Assault (Cutscene + Escape Sequence)

The chapter opens with a cinematic of the Genma's first major assault on a rural settlement. Once you regain control, the Oni Clan ally leads you through burning streets toward the village outskirts.

Section 2 — First Combat Encounters

After the alleyway, the ally forces you to pick up a wooden practice sword and face your first real Genma Brute. This is the basic combo tutorial.

Section 3 — Training Grounds

The ally escorts you to a small clearing with 5 wooden dummies. This is where you learn parry timing, soul absorption, and unlock the skill tree.

Section 4 — Forest Path

A linear path through the forest that connects the training grounds to the shrine approach. This is also your first real soul farming opportunity.

Hidden Cave Missable

The cave entrance is easy to walk past. Slow down at the second cliff section and look left for a faintly glowing rock formation. This cave contains a Talisman Fragment you cannot re-collect later without a save reload. See the Missables section below.

Section 5 — Shrine Approach

The final pre-boss sequence. You arrive at a small Oni Clan shrine at the village outskirts. NPC dialogue triggers To be verified at launch

4. Boss Fight — Marcellus

Chapter Boss · Tier-1 Duel

Marcellus

Attack Patterns: 5 Phases: 2 Parry Window: Generous Recommended Level: 1 – 3

Marcellus is a Genma-aligned officer who confronts the protagonist at the shrine approach. He's a teaching fight — the 5 attack patterns are deliberately telegraphed and the parry window is intentionally wide so first-time players can learn the timing before the harder elite fights in later chapters.

Quick tips:

  • 5 attack patterns — focus on the overhead slam (telegraphed by a 1-second wind-up).
  • Parry timing is generous — better to parry early than late in this fight.
  • Save your Issen for Phase 2 when his posture breaks and the yellow stagger bar appears.
  • Recommended level 1–3 — clear the Forest Path ambush twice for ~960 souls and buy Health Pool I before the fight.

Rewards: 500 yellow souls, Onimaru (already equipped), Marcellus's Charm accessory (+5% parry window).

5. Key Items & Collectibles

Item Location Effect
Onimaru Katana Shrine approach (cutscene reward) Starting weapon — balanced katana with default moveset
Health Vial x3 Village streets, Forest Path Restore 30% HP on use
Talisman Fragment Hidden cave (Forest Path) Upgrade material for talisman crafting
Soul Cache (Red) Forest ambush point +200 red souls
Soul Cache (Blue) Shrine approach +200 blue souls
Marcellus's Charm Boss reward Accessory — +5% parry window

6. Missables

Missables Warning

Chapter 1 contains three recoverable-from-save pickups. None of them are permanently missable if you make a manual save before the Marcellus fight, but two are easy to overlook in a first-time run.

7. Soul Farming Opportunities

Location Enemies Souls / Clear Respawns?
Forest Path ambush 6 Genma Brutes ~480 yellow Yes (checkpoint)
Hidden cave None (chest only) 200 blue One-time
Farming Tip

Recommended: clear the Forest Path ambush twice before the Marcellus fight for ~960 yellow souls. Spend 500 on Health Pool I from the skill tree, then save the rest for Chapter 2's Rapid Charge purchase. Don't buy weapons in Chapter 1 — the Onimaru is enough to clear the boss.
