The Genma are the demonic creatures you will be cutting down for the roughly 20 hours of Onimusha: Way of the Sword. They are not random monsters — they are creatures of the underworld dragged into Edo-era Kyoto by the supernatural force called Malice, and several of them are actively manufactured in Dokyo's underground laboratory. Understanding what each type does, how it telegraphs, and which of your four parry tiers it respects is the difference between chaining Issens in slow motion and getting swarmed in a corridor.
This guide covers the nature of the Genma, every standard enemy type and how to counter it, the elite and boss-tier threats, the soul-absorption competition that makes fights volatile, and the escalation design that will make the full release harder than the demo. For the underlying combat mechanics, pair this with our Combat Guide; for the one-hit-kill counter specifically, see the Issen Guide.
What Are the Genma?
The Genma are demons of the underworld. In Way of the Sword they are brought to Kyoto by Malice — the same supernatural force that is pulling the city out of the living world — and many are produced deliberately in Dokyo's lab. This origin matters because it tells you the Genma are not a natural ecosystem. They are a weapon, and the various types you meet are tuned for different combat roles: line-breakers, ranged harassers, damage sponges, and escalating puzzle-bosses.
The Soul Economy
The single most important thing to understand about Genma is that they participate in the same soul economy you do. When enemies die, they drop souls in three colors — yellow (health), red (upgrades/long-term currency), and blue (Oni Power Gauge and Oni Armaments, the scarcest). Souls spawn in the arena and are actively absorbed, and here is the catch: enemies can steal uncollected souls and power up.
This turns every fight into a race. Leave souls lying on the ground and a nearby Genma will absorb them, healing, gaining aggression, or unlocking new attacks. The game is aggressively designed around this — healing is tied to kills, the system pushes you forward, and finishers chain into more resources. The Genma are not passive targets waiting to be harvested; they are competing for the same fuel you are.
The single fastest way to lose a fight you were winning is to drop a Genma, walk past its souls, and watch the next enemy absorb them and escalate. Treat soul pickup as part of the attack animation, not an afterthought. Upgrade your gauntlet's absorption range and the ability to absorb while moving as early as you can.
Standard Genma Types
The bulk of your encounters will be against standard Genma soldiers, archers, and armored demons. Each has a distinct behavior, a distinct tell, and a distinct correct answer in the parry system. Master these three and the rest of the game opens up.
Genma Soldiers
Appearance: Humanoid demons armed with melee weapons — the baseline infantry of the Genma. They are the most common enemy and the one you will use to practice every system in the game.
Behavior: Soldiers close distance aggressively and chain two-to-three hit melee combos. They telegraph with a wind-up lean before the first swing, and they are the primary enemies that will try to absorb stray souls if you leave them on the ground. In groups they attempt to flank, with one engaging from the front while others circle.
Recommended counter: The timed parry is your workhorse here. Deflect the opening swing to pressure their stamina, then push the advantage. One-handed stance is ideal for handling their speed and for managing multiple soldiers at once because of its mobility. Against a lone, staggered soldier, a two-handed committed swing deletes a chunk of health.
Break Issen opportunity: Excellent. Soldiers are the textbook target for Issen — a perfect-frame counter on their telegraphed opening swing is a one-hit kill, and because Issen is chainable in slow-mo, a room of soldiers can be cleared in a single sustained counter sequence once you have the timing down.
Genma Archers
Appearance: Ranged Genma that hang back from melee, loosing arrows from the edges of arenas and elevated positions. They are the single most annoying enemy type if left unchecked.
Behavior: Archers fire on a rhythm, repositioning between volleys to keep distance. Their arrows interrupt your combos and, in groups, can stunlock you out of a finisher. They are fragile up close but will kite you, and chasing one often pulls you into a soldier's flank attack.
Recommended counter: The deflect tier is purpose-built for archers — it redirects arrows and can even steer them into other enemies or the environment. This is the tier that turns a harasser into a liability for its own team. Alternatively, the Oni Armament bow lets you answer fire with fire from range, and time slows when you switch armaments, giving you a clean window to line up a shot. One-handed stance's mobility helps close the gap to finish them in melee.
Break Issen opportunity: Low on the arrows themselves, but high once you close distance. Archers have no melee depth; once you are in their face, a single timed parry on their weak melee panic-swing sets up a clean Issen.
In any mixed encounter, kill or neutralize archers first. A deflected arrow is fine, but two archers firing on different timings will shred your posture and break your Issen chains. Use Oni Vision to spot archers hiding on ledges before they open fire.
Armored Demons
Appearance: Heavily plated Genma built to soak damage and force commitment. They are the damage sponges of the standard roster and the enemies most likely to punish a sloppy two-handed swing.
Behavior: Armored demons move deliberately and swing with high commitment. Their attacks are slower than a soldier's but hit much harder, and their armor shrugs off light one-handed strikes, meaning you cannot simply out-speed them. They are the enemies that teach you the difference between mashing and choosing your moment.
Recommended counter: Two-handed stance earns its keep here — its high damage is what actually chips through armor. But because two-handed swings are committed, you must earn your windows through the parry system first. Chain timed parries to build the blue meter (which ignites your katana blue, speeds up Break Issens, and adds damage), then unload two-handed punishment during the stagger. Oni Armaments like the dual clubs or spear are also strong against armor.
Break Issen opportunity: This is where Break Issen shines. Armored demons will not die to a single Issen the way soldiers do — you must first deplete their stamina through parries to trigger the Break Issen execution, which dismembers them. Patience here pays off: the break execution is far more efficient than trading blows.
Elite and Mini-Boss Genma
Beyond the standard three, you will encounter elite Genma — tougher variants and mini-bosses that combine traits of the standard types or introduce new mechanics. These are the enemies that gate area progression and drop meaningful soul rewards. Expect them to have enlarged health pools, additional attack strings, and tell variations designed to break habits you built fighting their lesser cousins.
Elites are also where the soul-stealing mechanic becomes genuinely dangerous. A mini-boss that absorbs a few stray red souls mid-fight can heal back your hard-won progress or unlock an AoE attack you have not seen. Against elites, the rule is absolute: finish the kill, immediately absorb, do not let the soul pile sit. Pair burst damage from Oni Armaments with a ready Break Issen to close the fight before the economy turns against you.
Boss Genma
The named bosses are the centerpiece encounters of Way of the Sword, and each is built around a distinct concept rather than inflated stats. The Break Issen system has a boss variant: instead of a one-hit kill, bosses use body-part targeting with color-coded zones, meaning you dismantle them piece by piece rather than executing them whole.
Shuten Doji
A colossal boss encountered at Mount Oe, the Genma-overrun mountain range. Shuten Doji claims to be the oni of legend, and his scale is the encounter — fighting something that large means the camera, the arena, and your positioning all matter as much as your parry timing. Expect sweeping attacks with long wind-ups but massive arcs, and use the deflect tier to steer his attacks into the environment where possible. Body-part targeting is essential: identify the color-coded zones and focus your Break Issens to systematically disable him rather than chipping a single health bar.
Dohatsu-Ten
A winged boss whose signature mechanic is that its sword grows on blood — meaning the longer the fight goes and the more damage is dealt (to either side), the more dangerous its weapon becomes. Dohatsu-Ten is an escalation fight: you are rewarded for efficiency and punished for attrition. This is where the red meter (three flawless dodges triggering a Reflex Combo and soul boost) becomes critical, because clean dodging both avoids feeding its sword and builds your own offense. Do not trade hits; every wound you take makes the boss stronger.
Byakue — The Hundred Defilements
A boss built from cursed paper talismans, with escalating danger as the fight progresses. Byakue is effectively a puzzle-boss about managing escalation — the talismans accumulate and the threat compounds, so the encounter rewards aggression and clean execution over a long, careful grind. Environmental tools and Oni Vision (to read the talisman patterns) are likely to matter here. Treat it as a DPS-and-control check: keep the defilement count down while you dismantle it.
Ningyo
A fish yokai that mimics a woman, Ningyo is the deception boss of the roster. Mimicry implies the encounter plays with recognition and misdirection — likely a fight where what you see is not exactly what you fight, and where rushing in on the wrong target gets punished. Oni Vision is your friend here, as it reveals hidden enemies and demonic presences that normal sight misses. Slow down, confirm your target, and apply the parry system to its true form.
For every boss, the Break Issen becomes a body-part execution on color-coded zones rather than a kill. Learn the zone colors early in the fight, then route your stamina-depleting parries toward the part you want to remove next. Disabling a boss's weapon arm or wing fundamentally changes the encounter — prioritize parts that are actively threatening you.
The Soul Absorption Competition
This deserves its own section because it is the mechanic that separates Way of the Sword from a standard action game. The soul economy is competitive, not just cooperative. Every soul on the ground is contested, and the Genma are playing to win it.
- Yellow souls (health): If an enemy steals these, it heals. A near-dead Genma that grabs a yellow soul undoes your work.
- Red souls (upgrades/long-term currency): If an enemy steals these, it powers up — gaining aggression, new attacks, or tougher defenses. This is the most dangerous theft, because it permanently escalates that enemy for the rest of the fight.
- Blue souls (Oni Power Gauge/Armaments): The scarcest. An enemy that absorbs blue souls can fuel its own supernatural attacks, turning a standard soldier into something approaching an elite.
The counter-strategy is aggressive absorption. Upgrade your Oni Gauntlet's absorption speed and range early, prioritize the absorb-while-moving upgrade, and build the habit of sweeping the arena for souls between engagements. The red meter's soul boost (from three flawless dodges) and the Oni Armaments' yellow-soul generation on hits give you tools to keep your own economy flowing even while denying the enemy theirs.
How Genma Interact with the Parry System
The four-tier parry system is not just a defensive tool — it is the lens through which you read every Genma. Each tier answers a different kind of attack, and matching the tier to the enemy is the core skill of combat.
- Hold to block: The safety net. Drains posture, so it is a last resort, not a strategy. Useful while learning a new enemy's patterns, but lean on it too long and you will be posture-broken.
- Timed parry: Deflects the attack and pressures the enemy's stamina. This is your default answer to soldiers and the primary tool for building toward Break Issens on armored demons.
- Deflect: Redirects attacks and arrows, and can steer enemies into the environment — torches, rocks, ledges. This is the answer to archers and the key to environmental combat.
- Issen: The perfect-frame counter. One-hit kills standard enemies and is chainable in slow motion. On bosses, it becomes the body-part Break Issen. This is the ceiling of the combat system.
The reactive buffs layer on top: chaining timed parries fills the blue meter, igniting your katana blue for faster Break Issens and bonus damage, while three flawless dodges fill the red meter for a Reflex Combo and soul boost. So the parry system is not just keeping you alive — it is actively building the resources that let you end fights faster.
Enemy Tells and Attack Patterns
Every Genma telegraphs, and learning the tells is how you move from reactive blocking to proactive Issens. A few universal principles:
- The wind-up lean: Soldiers and most humanoid Genma lean into their first swing. That lean is your Issen window.
- Repositioning before ranged volleys: Archers shift stance or side-step before firing. Watch the feet, not the bow.
- Armor shift on armored demons: Their plated sections glint or settle before a committed heavy swing — that is your cue to parry, not to attack.
- Boss color shifts: The color-coded body-part zones change state as you damage them. A zone shifting color often precedes a phase change or a new attack from that limb.
Oni Vision is the tell-reader for the things your eyes cannot catch. It reveals hidden enemies, Malice threads, and demonic presences, which means it is not just an exploration tool — it is a combat intel tool. Flicking Oni Vision before a messy multi-enemy pull can reveal an archer you would have walked into, or a hidden Genma waiting to flank.
Group Fight Strategies
Way of the Sword uses handcrafted arenas and a fixed level structure, not open-world wandering, which means group encounters are designed deliberately. Treat each room as a puzzle with a solution rather than a mob to survive.
- Kill archers first, always. Ranged pressure breaks your parry chains and prevents Issen timing. Close on them or deflect their fire into their allies.
- Use the environment to thin numbers. The deflect tier steers enemies into torches, rocks, and ledges. Tatami mats intercept arrows; kimonos can blind. A well-steered soldier off a ledge is one less Issen you have to land.
- Build the blue meter on the weak, spend it on the strong. Chain parries on soldiers to ignite your katana blue, then turn that buff on the armored demon while Break Issens are faster.
- Absorb between kills, not after the room. In a group fight, waiting until the room is clear means the next enemy has already eaten your souls. Sweep as you go.
- Switch armaments to control time. Time slows when you switch Oni Armaments. Use that slow window to reposition out of a flank, line up a bow shot, or reset a bad situation.
The most common group-fight death is committing to a two-handed swing on a soldier while a second enemy flanks you. Two-handed stance is committed — once you swing, you cannot cancel. Only commit when you have parried or killed everything that could punish the recovery. When in doubt, stay one-handed for mobility.
The Escalation Design: Demo vs. Full Game
If you played the demo, you have a skewed picture of the Genma. The demo deliberately equipped Musashi with late-game skills to showcase the combat system, which made both the regular Genma and the Kiyomizu-dera boss fight against Sasaki Ganryu easier than they will be in context. The producer has explicitly confirmed that bosses and regular Genma will be more demanding in the release build.
What this means practically: do not assume your demo timing will carry over unchanged. The tells may be tighter, the windows smaller, and the soul economy less forgiving. Treat the demo as a tutorial for the systems, not a benchmark for difficulty. When the full game arrives on September 4, 2026, expect to relearn enemy pacing and to lean harder on the parry tiers and Oni Armaments than the demo required.
Genma Enemy Type Table
The table below summarizes the standard roster at a glance. Use it as a quick reference during encounters.
| Enemy Type | Behavior | Threat Profile | Soul-Steal Risk |
|---|---|---|---|
| Genma Soldier | Aggressive melee combos; flanks in groups | Baseline; teachable Issen target | High — numerous, close to soul drops |
| Genma Archer | Ranged volleys; kites and repositions | Interrupts combos; stunlock in pairs | Medium — steals from range if unchecked |
| Armored Demon | Slow, committed heavy swings; soaks light hits | Damage sponge; punishes sloppy commitment | High — long fights mean more stray souls |
| Elite / Mini-Boss | Combined traits; new attack strings | Gates area progression | Critical — can heal or unlock AoE mid-fight |
Counter Strategy Reference
This is the table to memorize. It maps each enemy type to the parry tier, stance, and Oni Armament that answers it, plus the Break Issen window.
| Enemy Type | Best Parry Tier | Best Stance | Best Armament | Break Issen Window |
|---|---|---|---|---|
| Genma Soldier | Timed parry / Issen | One-handed (mobility) | Two Celestials (twin daggers) | Opening swing — one-hit kill, chainable |
| Genma Archer | Deflect (redirect arrows) | One-handed (close gap) | Bow (answer fire) | Melee panic-swing once closed |
| Armored Demon | Timed parry → Break Issen | Two-handed (chip armor) | Dual clubs / Spear | After stamina depletion — dismemberment |
| Elite / Mini-Boss | Mixed; read tells | Switch by phase | Wind-Whipper (control) | Stamina break → burst execution |
| Boss (e.g. Shuten Doji) | Deflect + timed parry | Two-handed (part damage) | Situational by zone | Body-part targeting on color-coded zones |
Putting It All Together
The Genma are a weapon system, not a bestiary of random monsters, and fighting them well means fighting them on those terms. Read each type for its role — line-breaker, harasser, sponge, escalation puzzle — and answer it with the parry tier and stance built for that role. Never let souls sit. Treat the deflect tier and the environment as force multipliers that thin groups without costing your stamina. And when you reach the bosses, remember that the Break Issen becomes body-part surgery: identify the zones, dismantle the threatening parts, and let the fight get easier as you go rather than harder.
Most of all, recalibrate from the demo. The full game will demand more from your timing, your soul discipline, and your willingness to commit two-handed swings only when the window is truly safe. The Genma are designed to punish hesitation and greed in equal measure — the player who chains clean parries, absorbs aggressively, and steers enemies into the environment will find them far less daunting than the one who treats each fight as a stat check.
