Onimusha: Warlords does not have a traditional carry-everything New Game Plus. Instead, finishing the campaign unlocks Ultimate Mode, which is the game's version of a powered-up second playthrough. In Ultimate Mode, Samanosuke begins the campaign with his elemental weapons -- Raizan, Enryuu, and Shippuu -- already at maximum level, along with maxed magic and, in many versions, the Bishamon Sword. This lets you tear through the story that previously tested you.
What does not carry over verbatim is your exact save-state inventory and progress. Ultimate Mode is a fresh run with preset maxed gear, not a continuation of your completed save's items and collectible progress. So if you missed Fluorites or jewels on your first run, Ultimate Mode is the cleanest way to hunt them, but you are replaying from the start rather than resuming mid-castle.
Treat the first playthrough as your learning and leveling run and Ultimate Mode as your completion and cleanup run. This two-pass approach is the intended way to experience everything Warlords offers without grinding against the difficulty curve.

Ultimate Mode Explained
Ultimate Mode is the headline reward for beating the game, and it transforms the feel of the campaign. With maxed weapons from the opening minutes, enemies that were dangerous on a first run become trivial, and bosses that demanded patience can be burst down with maxed magic. This makes Ultimate Mode ideal for two things: mopping up collectibles and attempting challenge achievements like no-heal or time-limited stage clears.
Because combat is no longer a wall, you can focus on exploration. Sweep each area for Fluorites, Power Jewels, and Magic Jewels with a checklist, since maxed gear means nothing slows you down. The fixed camera still hides items, so the checklist matters more than your power level.
One caveat: Ultimate Mode can make the game feel too easy, which is great for cleanup but less satisfying for combat. If you want a challenge on your second run, crank the difficulty -- the maxed gear still helps, but higher-difficulty enemies hit hard enough to keep you honest. Balance cleanup runs on lower difficulty with challenge runs on higher difficulty as you see fit.
The Dark Realm on a Second Playthrough
The Dark Realm survival mini-game is the other major post-game unlock, and it pairs perfectly with New Game Plus-style play. Unlocked after your first clear, it is accessed through an Oni shrine and tasks you with descending through waves of Genma. Reaching the bottom rewards the Bishamon Sword, which then carries into Ultimate Mode and makes an already easy mode even more dominant.
The smart order is to unlock the Dark Realm, clear it once to claim the Bishamon Sword, and then start your Ultimate Mode run with the ultimate weapon in hand. This gives you the strongest possible toolkit for hunting the remaining collectibles and achievement-specific challenges. The Dark Realm is also the best soul farm in the game, so a deep run before Ultimate Mode can bank resources where a version allows banking.
If you find Ultimate Mode too easy even with the Bishamon Sword, the Dark Realm itself remains a genuine challenge regardless of your campaign gear, because its late waves are balanced to test maxed characters. It is the place to find real difficulty after the story stops providing it.
Best Uses for a Second Playthrough
The best use of a second playthrough is 100% completion. Use Ultimate Mode, ideally with the Bishamon Sword already earned from the Dark Realm, to sweep every Fluorite, Power Jewel, and Magic Jewel you missed. Maxed gear removes the combat friction that made thorough exploration tedious on a first run, so a completion sweep becomes a quick, enjoyable pass rather than a chore.
Your second run is also the time to chase combat and rank achievements that were too risky on a first playthrough. No-heal stage clears, time-limited chapter runs, and S-rank stages are all far more achievable when your weapons kill fast enough that you take little damage and clear quickly. Pair maxed gear with a checklist of achievement conditions and knock them out systematically.
Finally, use the second run to experiment. On a first playthrough, conservative play is smart; on Ultimate Mode, you can afford to test every elemental weapon, practice Issen counters against every enemy type, and learn boss patterns without fear of failing the run. The result is a player who has truly mastered Warlords rather than simply survived it.
