The demo boss tests everything you've learned about parry timing and Issen execution. This guide breaks down every attack pattern, the optimal parry windows, and the best strategy to win consistently.
Boss Overview
The demo boss is a Genma Oni — a corrupted samurai-warrior hybrid that serves as the gatekeeper to the demo's conclusion. It appears at the end of the opening section, after you've cleared the shrine, gorge, and village encounters. The fight is designed as a combat exam: it tests whether you've internalized the parry timing, stance switching, and stamina management the demo has been teaching you. If you've been button-mashing your way through the standard enemies, this fight will stop you cold.
The boss has two phases. Phase 1 is a measured, telegraph-heavy duel that rewards patient parry play. Phase 2 triggers at roughly 50% health, when the boss becomes enraged — attack speed increases, new combos unlock, and the parry windows tighten. The difficulty jump between phases is significant but fair: every tool you need to win phase 2 is introduced in phase 1, so if you're struggling in phase 2, the issue is usually execution, not knowledge.
In terms of difficulty, the demo boss is moderately challenging for action-game veterans and a genuine wall for newcomers. Expect 3–5 attempts on a first playthrough if you're learning the patterns from scratch. By attempt 5–7, most players can clear it consistently. The demo allows unlimited retries, so treat each death as a learning opportunity rather than a setback.
| Attribute | Details |
|---|---|
| Boss Name | Genma Oni (Demo Boss) |
| Chapter | Opening section (end of demo content) |
| Difficulty | Moderate (veterans) / Hard (newcomers) |
| Phases | 2 (Phase 2 triggers at ~50% HP) |
| Estimated Attempts | 3–5 (first clear), 1–2 (mastered) |
| Retry Limit | Unlimited (demo allows free retries) |
Your first 1–2 attempts should be pure observation. Don't try to win — just survive and watch the boss's attack patterns, tells, and recovery windows. Identify which attacks you can parry, which you should dodge, and which are unblockable. Once you can read the boss, the fight becomes a rhythm exercise. Trying to win before you understand the patterns is the fastest path to frustration.
Attack Patterns
The demo boss has seven distinct attacks across both phases. Each one has a visual tell — a wind-up animation that signals what's coming — and an optimal defensive response. Learning to read these tells is the core skill the fight demands. Here's the complete breakdown.
| Attack Name | Tell | Parry Window | Best Counter |
|---|---|---|---|
| Overhead Slash (Phase 1) | Boss raises sword overhead, brief pause at apex | Wide (~0.4s on impact) | Timed parry (tier 2) → two-handed punish |
| Horizontal Sweep (Phase 1) | Boss pulls sword to side, torso twists | Medium (~0.3s) | Timed parry or dodge backward |
| Thrust Stab (Phase 1) | Boss draws sword back to hip, steps forward | Tight (~0.2s) | Dodge sideways (do not parry — hitbox is narrow) |
| Three-Hit Combo (Phase 1) | Boss shifts weight to back foot, sword dips low | Medium (parry first hit, dodge rest) | Parry first swing, dodge remaining two |
| Ground Slam (Phase 1) | Red flash on weapon, boss leaps upward | N/A (unblockable) | Dodge away immediately on red flash |
| Enraged Rush (Phase 2) | Boss glows crimson, lunges forward with 4-hit string | Tight (first hit only) | Dodge backward, punish after string ends |
| Area Shockwave (Phase 2) | Boss plants sword in ground, radial pulse | N/A (unblockable AoE) | Dodge out of range before pulse expands |
Any attack preceded by a red flash on the boss's weapon is unblockable — it cannot be parried or blocked. Your only option is to dodge. Train yourself to react to the red flash instinctively: see red, dodge away. Trying to parry an unblockable attack is the most common cause of demo boss deaths.
Phase 1 Strategy — The Measured Duel
Phase 1 is about patience and pattern recognition. The boss uses five attacks — the Overhead Slash, Horizontal Sweep, Thrust Stab, Three-Hit Combo, and Ground Slam — in a semi-randomized sequence. Your job is to identify each attack from its tell and respond with the correct defensive action.
The Core Loop
The optimal phase 1 rhythm is: read the tell → choose your response (parry, dodge, or reposition) → punish the recovery window → reset to neutral. Stay in one-handed stance throughout phase 1 for maximum mobility and fast recovery. Only switch to two-handed for punish windows — a single heavy attack after a successful parry, then immediately back to one-handed.
The Overhead Slash is your bread-and-butter parry opportunity. Its tell is generous — the boss raises the sword overhead and pauses at the apex for a visible moment before swinging down. The parry window on impact is wide, roughly 0.4 seconds, making it the most forgiving parry in the fight. Land this consistently and you'll drain the boss's stamina faster than any other approach.
Handling the Three-Hit Combo
The Three-Hit Combo is the trickiest phase 1 pattern because it mixes parryable and dodgeable hits. The tell is a weight shift to the back foot with the sword dipping low. Parry the first swing — it's a standard horizontal with a medium window — then immediately dodge backward for the remaining two hits. Do not try to parry all three; the second and third swings come too fast for reliable parry timing, and a missed parry mid-combo means eating two hits.
The Ground Slam
The Ground Slam is the phase 1 unblockable. It's telegraphed by a red flash on the boss's weapon and a leaping wind-up. The moment you see the red flash, dodge directly away from the boss — not sideways, away. The slam has a small AoE on impact, so you need distance, not just lateral movement. After the slam lands, there's a generous recovery window where the boss is locked in animation. Use it for a free two-handed heavy punish before resetting.
Don't try to rush phase 1. Your goal is to deplete the boss to 50% health while taking as little damage as possible and building your confidence with the parry timing. Light attack chips between the boss's strings are perfectly fine — you don't need to land every punish. Phase 1 is about setting up a clean phase 2 transition with full health and a stocked healing inventory.
Phase 2 Strategy — The Enraged Oni
At roughly 50% health, the boss enters phase 2. A cinematic transition plays — the boss roars, crimson energy flares across its body, and its weapon gains a spectral aura. The phase 2 difficulty jump is real: attack speed increases by roughly 30%, two new attacks are added (Enraged Rush and Area Shockwave), and the parry windows on existing attacks tighten slightly.
New Attack: Enraged Rush
The Enraged Rush is the signature phase 2 attack. The boss glows crimson and lunges forward with a four-hit string that's significantly faster than the phase 1 Three-Hit Combo. The first hit has a tight parry window, but the subsequent three come too fast to parry reliably. The optimal response is to dodge backward on the crimson glow and wait for the string to end, then punish the boss's recovery animation. Do not try to parry the full string — it's designed to punish greedy players who try to stand their ground.
New Attack: Area Shockwave
The Area Shockwave is the phase 2 unblockable. The boss plants its sword in the ground, sending out a radial pulse of energy that expands outward. The tell is the sword-plant animation — there's a brief window before the pulse expands where you can dodge out of range. If you're caught inside the pulse radius when it expands, you'll take significant damage regardless of blocking or parrying. The key is distance management: when you see the sword plant, sprint or dodge outward immediately.
Adapting Your Phase 1 Habits
The phase 1 attacks don't disappear in phase 2 — they just come faster. The Overhead Slash's parry window tightens from ~0.4s to ~0.3s, and the boss chains attacks more aggressively, leaving less recovery time between strings. You'll need to punish faster and reset quicker. A good rule of thumb: if you landed a two-handed heavy after a parry in phase 1, consider switching to a light attack punish in phase 2 to avoid getting caught in the boss's next string before you can reset.
Stagger Windows in Phase 2
The boss's stamina depletes faster in phase 2 because it attacks more aggressively. This means stagger windows — the moments when the boss's stamina hits zero and it's briefly stunned — come more frequently. Use these windows for maximum damage: two-handed heavy attacks, and if your Oni Gauge is charged, this is the time to unleash it. Phase 2 stagger windows are your primary damage source, more so than chip damage between strings.
The most common phase 2 death is getting greedy on a punish. You land a parry, switch to two-handed, and start a heavy attack combo — but the boss recovers faster than you expect and hits you mid-animation. In phase 2, limit your punishes to one or two hits max, then reset to neutral. Greed is punished harder in phase 2 than in any other part of the demo.
Parry Timing Guide
The parry is your most important tool in this fight. A successful timed parry deflects the attack, drains the boss's stamina, and opens a punish window. A failed parry means you eat the full damage. The key to consistent parrying is learning to read the impact frame — the exact moment the boss's weapon would connect — and timing your input to that frame, not to the start of the animation.
For a visual breakdown of the four-tier parry system and detailed timing diagrams, see our Deflect & Parry Guide. For this fight specifically, here are the parry windows you need to internalize:
| Attack | Phase | Parry Tier | Timing Cue | Window Est. |
|---|---|---|---|---|
| Overhead Slash | 1 | Timed parry (tier 2) | Tap as sword begins descent from apex | ~0.4s |
| Overhead Slash | 2 | Timed parry (tier 2) | Tap at descent start (faster wind-up) | ~0.3s |
| Horizontal Sweep | 1 | Timed parry (tier 2) | Tap as torso unwinds toward you | ~0.3s |
| Three-Hit Combo (1st hit) | 1 | Timed parry (tier 2) | Tap on first swing's impact | ~0.3s |
| Enraged Rush (1st hit) | 2 | Timed parry (tier 2) | Tap on lunge impact (very tight) | ~0.2s |
| Thrust Stab | 1 & 2 | Dodge (not parryable) | Dodge sideways on forward step | N/A |
| Ground Slam | 1 & 2 | Dodge (unblockable) | Dodge away on red flash | N/A |
| Area Shockwave | 2 | Dodge (unblockable) | Dodge out of range on sword-plant | N/A |
The boss's body animates dramatically — torso twists, weight shifts, roars — but the parry timing is tied to the weapon's impact frame, not the body animation. Train your eyes on the boss's sword. The moment the blade begins its descent toward you is your parry cue. Body tells help you identify which attack is coming; weapon tells tell you when to press the button.
Issen Opportunities
The Issen is the perfect-timing counter — a strike that lands at the exact frame an enemy attack would connect, dealing massive damage and, on standard enemies, a one-hit kill. On the demo boss, the Issen doesn't one-shot, but it deals significantly more damage than a standard heavy attack and drains a large chunk of boss stamina. Landing an Issen in this fight is the highest-leverage play you can make.
When to Attempt Issen
The Issen window is extremely tight — tighter than a standard timed parry — and attempting it carries risk: if you mistime the input, you eat the full attack. Don't attempt an Issen on an attack you haven't mastered the parry timing for. The rule of thumb is: if you can parry the attack 9 out of 10 times, you're ready to start attempting the Issen on it.
The best Issen opportunities in the demo boss fight are:
- Overhead Slash (Phase 1) — The wide parry window makes the Issen window accessible. Time your attack input to the impact frame of the descending sword. A successful Issen here drains roughly 20% of the boss's stamina bar per hit.
- Horizontal Sweep (Phase 1) — The torso unwind gives a clear timing cue. Strike as the blade reaches your position. Slightly riskier than the Overhead Slash but still approachable.
- Overhead Slash (Phase 2) — The window tightens, but the tell is the same. If you've mastered the phase 1 version, the phase 2 Issen is achievable with practice. The damage payoff is higher in phase 2, making it worth the risk.
When NOT to Attempt Issen
Never attempt an Issen on the Three-Hit Combo, the Enraged Rush, or any unblockable attack. The multi-hit strings will punish a mistimed Issen with follow-up hits that you can't dodge out of, and unblockable attacks can't be Issen-countered at all. Stick to standard parry-and-dodge for these patterns.

Recommended Build
The demo's skill tree is a restricted subset of the full game's options, but the choices you make before the boss fight matter. You'll want to prioritize survivability and parry efficiency over raw damage, because the fight is won through consistent defensive play, not burst damage.
Skill Priorities
Before entering the boss arena, aim to have the following skills purchased with the souls you've collected through the demo's opening section:
- Health Boost (Tier 1) — Increases maximum health. This is the single most impactful upgrade for the boss fight. Extra health gives you more room for error, which is critical when you're learning phase 2 patterns. Prioritize this above everything else.
- Parry Stamina Efficiency (Tier 1) — Reduces the stamina cost of successful timed parries. This lets you parry more frequently without depleting your own stamina, which is essential for sustained defensive play in phase 2.
- Two-Handed Damage (Tier 1) — Increases heavy attack damage in two-handed stance. This makes your punish windows more efficient — each parry punish deals more damage, so you need fewer successful punish cycles to clear the fight.
- Dodge Distance (Tier 1) — Increases dodge roll distance. Helpful for creating space during phase 2 unblockable attacks and the Enraged Rush. Not essential, but a quality-of-life upgrade that makes the fight more forgiving.
| Skill | Priority | Why |
|---|---|---|
| Health Boost (Tier 1) | 1st — essential | More room for error while learning patterns |
| Parry Stamina Efficiency (Tier 1) | 2nd — essential | Sustain parry play in phase 2 without stamina depletion |
| Two-Handed Damage (Tier 1) | 3rd — recommended | Faster punishes, fewer cycles needed to clear |
| Dodge Distance (Tier 1) | 4th — optional | More forgiving dodges on unblockable attacks |
The demo gives you enough souls to purchase 2–3 tier 1 skills depending on your collection efficiency. Don't dump everything into a single branch — a balanced investment in health, parry efficiency, and damage gives you a more well-rounded build than maxing one stat.

Rewards
Defeating the demo boss grants several rewards, both within the demo and as carry-over bonuses for the full game. The fight is worth clearing — and worth replaying — for the resources it provides.
| Reward | Type | Notes |
|---|---|---|
| Large Soul Payout | Souls | Significant soul reward, transfers to full game balance |
| Demo Completion Bonus | Souls + Items | Granted on first boss clear; bonus souls and consumables in full game |
| Oni Gauntlet Charge | Progression | Advances the gauntlet's story charge level (cosmetic/lore in demo) |
| Demo Cleared Flag | Save Data | Marks demo as complete; triggers carry-over bonus on full-game load |
The boss's soul payout is the single largest soul source in the demo, making the fight worth replaying if you want to maximize your carry-over resources for launch. Each replay of the boss grants the full soul payout again, compounding your head start. For players aiming to enter the full game with a strong soul surplus, 2–3 boss replays after your first clear is an efficient use of demo time.
Don't just replay the boss for the soul payout — use each replay to sharpen your execution. By your 5th clear, you should be parrying the Overhead Slash consistently. By your 10th, you should be attempting Issens on it. The muscle memory you build here transfers directly to the full game's boss encounters. Treat the demo boss as a sparring partner, not just a loot source.
