Onimusha Walkthrough: Full Chapter Guide & Bosses

Quick Answer: Campaign Route & Progression Strategy

Direct Answer: Onimusha: Way of the Sword features a structured 10-chapter linear campaign set across historical Edo-period Kyoto. To advance smoothly, prioritize unlocking shortcut kickdown ladders and purifiable Torii gates that link outer labyrinth zones back to central Kishin Shrines (鬼神像). Level up Raizan (Thunder Katana) to Level 2 in Chapter 2, unlock Enryu (Flame Greatsword) in Chapter 4, and gather red souls via precision Issen counters rather than mindless mob grinding.
