This route is for the base-game campaign through Chapter 19. It follows the current PC and console rules after the March 4, 2026 Version 1.004.000 update. The separate The Two Masters story is not part of this walkthrough. Story and boss spoilers begin with the chapter table.
NINJA GAIDEN 4 rarely hides the main exit. The real campaign problem is knowing when a fast traversal sequence is about to carry you past a mission branch, a DarkNest hand-in, or a safe restock. Use the route below as a set of decision points: accept every available mission, clear nearby branches before the next rail, glider, or portal sequence, and make a new manual save at each chapter boundary. That produces a clean first clear without turning every combat room into a collectible hunt.
The campaign rule that prevents most restarts
At every DarkNest terminal, perform the same three actions in this order: submit completed missions, accept every newly available mission, then buy or restock. Some mission chains do not expose the next assignment until the previous one is handed in. A blue objective can also sit just off the story lane, so an accepted task is much easier to recognize than an item found with no active context.
For Yakumo’s early skill economy, buy mobility and counter tools before long weapon strings. Flying Swallow helps close distance, Izuna Drop converts a launcher into a controlled removal, and Fatal Flash turns a successful defensive read into damage. Perfect Block and Perfect Dodge are not interchangeable: use the one whose timing you can reproduce, then add the counter. The March 2026 patch added startup invulnerability to Perfect Fatal Flash timing and several named weapon moves, improved Wind Run homing, and expanded Twin Blades cancel options. If an older video shows a recovery trap that no longer happens, test it in your current client before changing the route.
Keep at least two campaign saves. Slot A is the start of the current chapter; Slot B is the last terminal before a boss or forced traversal sequence. Profile-based collectible progress is helpful later, but it is not a substitute for a chapter-start save when you want to repair an unfinished mission immediately.
Twenty chapters, twenty exit checks
| Chapter | Main route checkpoint | Do not leave until |
|---|---|---|
| 00 — Dark Descendant | Use the tutorial fights to learn Base versus Bloodraven actions. | You can deliberately interrupt a red power attack instead of mashing through it. |
| 01 — Bloodsoaked Tokyo | Follow the Caddis Wire route across rooftops to the D.D.O. Commander. | All offered DarkNest missions are accepted and you have restocked before the commander. |
| 02 — Haunted District | Ride the marked monorail lanes and clear flying units before committing to the next rail. | You have checked the alternative, non-orange track branches you intended to visit. |
| 03 — Phantom Pleasure Quarter | Climb the opening shaft, loop through the temple detour, and return to the Courtesan. | The forced left detour and nearby dead-end mission rooms are cleared. |
| 04 — Pilgrim’s Windswept Path | Learn the Dragonfly Glider, then use air streams and canyon grapples to reach the shrine. | You have cleared any canyon branch before taking the next long glide. |
| 05 — Raging Valley | Work through caves and temple courtyards, then leave Sanzeon’s arena by the side exit. | You have restocked and checked the temple detours before the boss. |
| 06 — Guiding Winds | Alternate glider bursts, cliff grapples, and narrow temple paths. | You have supplies for an extended run with few forgiving reset points. |
| 07 — Altar of the Mountain God | Take the short mountain approach into Kurobo’s arena. | You have used the opening terminal; the next meaningful stop is after the boss. |
| 08 — Drowned District | Descend the spiral route, unlock the Pond Strider, and break the correct portal to continue. | Side passages near the first two-portal room are done before surfing onward. |
| 09 — Realm of Silent Dead | Treat the flooded area as a hub: left cave, orange-gate route, crystal realm, then story exit. | You know which return from the crystal realm advances the story and which branch is cleanup. |
| 10 — Bounding Spirits | Chain surf, dimensional transitions, and the long descent into Cetus. | You have restocked before the point-of-no-return descent. |
| 11 — Infiltration | Use Kage-Hiruko on rails and ranged threats, then follow the train-switch route. | You took the safe rail after the train and are ready for the D-1018 Chariot. |
| 12 — Dragon’s Maw | Push through the D.D.O. stronghold, laser corridors, elevators, and repeated arenas. | Every accepted stronghold mission is handed in and your reserve items are not exhausted. |
| 13 — Clash of Convictions | Prepare at the opening area, then commit to Kagachi and Achilles in sequence. | You have a boss save and a full healing loadout. |
| 14 — Unholy Descent | Ryu’s playable introduction is a single Achilles encounter. | You have tested Ryu’s Ninpo, Gleam form, and movement before ending the practice fight. |
| 15 — Fanged Gate | Build Ryu’s kit through sewer and underworld chests, then drop into Cetus. | You opened every convenient skill-scroll chest; Ryu cannot buy his missing basics like Yakumo. |
| 16 — Downpour | Cross familiar Sky City lanes, loop through the Pleasure District, then face the Courtesan. | You repaired Ryu’s health and skills before the late-chapter fight. |
| 17 — Howling Ravine | Climb the ravine, clear its gate branch if desired, then rematch Kurobo. | Your accessory and Ninpo setup favors a single-target duel. |
| 18 — Darkness Reborn | Infiltrate the stronghold as Ryu and fight Totyos. | You collected the nearby health upgrade and saved before the phase change. |
| 19 — Ebon Wings | Return to Yakumo, clear the final branches, then fight Ryu, the Dark Dragon, and its Phantom. | All shopping and mission hand-ins are done before the final sequence. |
Chapters 00–03: build a repeatable combat loop
Dark Descendant
The prologue is where to separate ordinary pressure from Bloodraven commitment. Base attacks and time refill the Bloodbind gauge; Bloodraven actions spend it to break powered defenses and answer red attacks. Against tutorial guards, stop after a short string and watch what the enemy does. If your string leaves no time to block, shorten it. Practice Flying Bird movement and assassination when prompted, but make the red-attack interrupt your graduation test: recognize the glow, change form, land the appropriate power response, then take the stagger instead of continuing a blind combo.
Bloodsoaked Tokyo
Chapter 1 introduces the campaign’s normal rhythm: rooftop traversal, a terminal, an optional lane, then a set-piece fight. Accept every terminal mission before moving. In mixed groups, remove missile and gun enemies first; a melee opponent can be blocked in front of you, while a projectile arriving from outside the camera breaks otherwise sound timing. The Caddis Wire prompts are route locks, so finish any visible side alley before the second long gap.
The D.D.O. Commander is the first route check rather than a build check. Do not chase every retreat. Hold a distance where you can see the wind-up, interrupt his powered commitment, and punish the recovery. If he repeatedly catches your Bloodraven startup, you are answering the flash too late or beginning from the end of a long Base string. Shorten your pressure and rebuild the gauge on safe hits.
Haunted District
Chapter 2 mixes rails with airborne enemies. Clear targets before jumping to a rail whenever the arena permits; shooting while grinding is a traversal tool, not a reason to carry a full combat room into the next obstacle. The optional route signal is an unlit or differently aligned track near the blue-container sections. If the destination marker points to the obvious orange rail, a parallel route is usually a branch rather than progress.
Proto-Goliath rewards position more than greed. Attack a leg from an angle that keeps its body in view, move when the machine plants for a sweep, and use the opening after its committed motion. If the camera is filled by armor and you cannot see the next tell, disengage; one lost punish is cheaper than an unseen knockdown.
Phantom Pleasure Quarter
After the opening vertical shaft, turn back for the dead-end branch before crossing the obvious bridge. Later, when the temple closes the direct door, the forced left loop is real progress; search its small rooms before rejoining the central route. Burabura lanterns now drop essence unless they self-destruct under the current patch, so interrupt or finish them rather than retreating until they explode.
The Kitsune Courtesan appears as both a route boss and a lesson in restraint. Clear the real openings after her pattern, then stop when she begins the pulse or clone-like pressure. Version 1.004.000 fixed a case where her Chapter 3 pulse invalidated an Untouchable run, but the pulse is still a danger signal, not a damage window.
Chapters 04–07: traversal becomes the resource test
Pilgrim’s Windswept Path teaches the Dragonfly Glider. Air streams are effectively one-way doors: take the side canyon, shrine, or ledge before launching into the next stream. When a glide ends at a wrecked train or platform, land, scan for chests and the return route, and only then follow the marker. A failed glide should be corrected by lining up earlier, not by making last-second steering changes that sacrifice the next grapple.
Raging Valley alternates caves with temple courtyards. In the three-torch cave junction, a flowered wall marks an optional climb; in the four-temple area, finish the courtyard branches before the boss route. Sanzeon teleports, so center the camera after each disappearance rather than swinging at the last location. Save Bloodraven for the laser or committed power sequence. When the fight ends, check the edge of the arena before following the exit; at least one mission object sits on that post-boss transition.
Guiding Winds is the chapter to treat health as a route resource. The opening broken bridge is a quick optional check. Later, a short glider landing on wooden canyon platforms has a branch across the opposite grapple. Complete it before the main leftward route. The difficult middle stretch is easier if you pull enemies back to a narrow platform, eliminate ranged threats, then advance. A March 2026 fix addressed an out-of-bounds progression failure here, so update the game instead of following old workaround videos that ask you to clip or restart around the broken state.
Altar of the Mountain God is short enough that the opening terminal is your real preparation room. Take the descending stairs if you want the nearby optional branch, then return and climb to Kurobo. During the fight, his winged sequence ends in the actionable commitment; block or evade the lead-in and answer the ending power attack. When the battle moves into a glider phase, altitude and alignment matter more than extra attacks. Pass above or around the strafe, settle into the next stream, then resume pressure.
Chapters 08–10: navigate the drowned hub without circling it
Drowned District gives you the Pond Strider and immediately tests whether you distinguish a portal room from a corridor. After the spiral descent, explore the side pipe opposite the main turn. In the room with two enemy portals, destroy the required threat, then check the right-hand hallway and upper pipe before taking the left story exit. If you are back at the same disco-ball landmark without a new gate or door open, you followed the cleanup loop rather than the progression lane.
Realm of Silent Dead is the campaign’s largest navigation problem. On first reaching open water, use a simple sweep: left shoreline cave first, then the route under the large orange gate, then the crystal-realm transition. After passing beneath the gate, hugging the left wall leads to a short cave; the central water lanes are for continued progress. On returning from the crystal realm, reorient from the most recent terminal instead of trying to preserve your old camera direction. The second crystal visit uses a vertical climb before the next surf; a side ledge there is optional, while the straight surf continues.
Veilotl is the exit check. Keep space for the body and tail motion, remove spawned pressure before it blocks your view, and counter the committed attack rather than trading into armor. If you reach the fight with an empty reserve, the problem began in the hub: reload the last terminal save and skip already-cleared detours.
Bounding Spirits compresses several movement systems into one chapter. Clear the Purgatory branch near the opening if you intend to do it now, because the later surf and dimension sequence is a poor place to turn around. During the long descent, steer toward the next visible anchor instead of following debris. Cetus is fought after a resource-heavy approach: when it dives, rebuild your position and charge only if you can still see the re-entry cue. When it begins the missile pattern, use the intended surf-and-Bloodraven response to interrupt rather than trying to absorb the projectiles.
Chapters 11–13: preserve a boss loadout through the stronghold
Infiltration is a Kage-Hiruko tutorial disguised as a rail chapter. Use its ranged option on drones and launcher enemies, but do not stay on a rail merely because a target remains alive. One platform with several chests is a deliberate dismount; jump off in time, loot it, and then rejoin the route. At the train switch, take the rail that follows behind the passing train to reach the side platform. The D-1018 Chariot is safest from its rear quarter after a committed movement. If the front weapon can still track you, you have not reached the punish window.
Dragon’s Maw is long and should be played in sections: stronghold entry, laser and hourglass corridors, elite arenas, then the elevator sequence. Submit missions whenever the terminal allows it. In laser rooms, solve movement first and fight second; pulling an enemy through a safe doorway is better than parrying while a hazard crosses the arena. The March patch fixed missing NinjaCoin or Weapon EXP when enemies fell from the Chapter 12 stage, but intentionally throwing every target off an edge still makes resource gains harder to read. Kill priority targets on stable ground when practical.
Clash of Convictions begins with the last clean preparation window before two consecutive duels. Kagachi rewards pressure after a parry, but his phase change adds wide sweeps that require the wall hooks or a full reposition. Stop attacking when he draws the sword back for an unblockable commitment. Against Achilles, Kage-Hiruko lets you hold a safer lane and answer after a miss. Do not spend the entire inventory finishing Kagachi if a consistent counter cycle will do; Achilles is the second half of the checkpoint.
Chapters 14–19: rebuild around Ryu, then return to Yakumo
Unholy Descent temporarily removes the normal risk: use the Achilles encounter to learn Ryu. His movement is more deliberate than Yakumo’s, Gleam replaces Bloodraven, and Ninpo gives him several ranged or area answers. Cycle through those tools before ending the fight. The knowledge matters more than the result because Chapter 15 begins Ryu’s real resource curve.
Fanged Gate sends Ryu through the sewers and underworld. Open the early chests: unlike Yakumo, he acquires core combat skills from scrolls. The exact skill in a later scroll can be curated by what you already know, so route advice should track unopened chests, not promise that every player will receive the same move from the same box. Explore the central flooded island and side tunnels, return to the story gate, restock, then drop to Cetus. Ryu lacks the same surf arena, so wait for the surface commitment and punish rather than chasing the dive.
Downpour revisits Sky City and the Pleasure District. Use familiar geometry, but do not assume old doors and branches serve the same purpose. The side platform across from the objective contains critical Ryu progression, and several skill chests sit behind breakable boxes or short loopbacks. The Courtesan rematch adds pressure to the known pattern; preserve Ninpo for crowd or spacing control and punish only after the recognizable end of her string.
Howling Ravine is a focused climb and Kurobo rematch. Pull clustered Tengu through narrow passages instead of fighting them beside a large ranged fiend. For Kurobo, Ryu’s single-target accessories and consistent parry matter more than traversal damage. The winged sequence follows the same basic rule as the earlier fight: survive the approach, counter the committed end.
Darkness Reborn ends Ryu’s run. Totyos has a measured first phase and a violent second one. Use the first phase to confirm the parry rhythm and create a real stun; spend the strong damage boost during that stun. Once the spikes and rapid weapon swaps appear, a slow defensive loop loses ground. Use your stocked damage items, keep pressure through safe cancels, and trigger the True Dragon Sword finisher when available rather than saving everything for a chapter that Ryu will not play.
Ebon Wings returns to Yakumo for the finale. Re-equip his weapon and accessory plan immediately; do not assume Ryu’s last setup carried over in the form you want. Clear the final mission, Gourdy, health, and Purgatory branches before the boss run if they matter to this save. Against Ryu, use Kage-Hiruko to interrupt or create distance and take only confirmed recovery windows. Version 1.004.000 fixed a case where Ryu could leave the arena, so an updated client should not need a restart workaround.
The Dark Dragon’s first form is a movement fight: stay able to reach the grapple points, evade the large area attacks, and use Kage-Hiruko to interrupt special commitments even at range. Defeating it creates a checkpoint before the Phantom, so a death to the Phantom does not require repeating the monster form. Against the Phantom, ordinary weapon damage is poor. Use the Dark Dragon Blade’s intended power and convert a clean launcher into Izuna Drop when the opening is real. If the Phantom blocks or escapes the starter, reset spacing rather than forcing the rest of the string.
What to repair in New Game Plus
After the base campaign clear, New Game Plus can retain learned combat and weapon techniques, both currencies, and maximum-health progress. It also exposes chapter selection and lets you replay the campaign with Ryu. Use it to repair a chapter, not to repeat the entire route blindly: select the chapter with the missing profile check, accept the relevant terminal mission again if required, collect or complete the target, then continue until the next checkpoint confirms the save.
Purgatory completion needs special care. A gate cleared only through the separate challenge menu may satisfy a challenge objective but not the story-chapter gate record used by the Annihilator achievement. For a missing story gate, enter it from the actual chapter in New Game Plus and advance to a checkpoint afterward. The collectible package provides the chapter-by-chapter audit; this walkthrough intentionally stops at route handoffs rather than duplicating every item coordinate.
