A Tempest at the Temple is the fifteenth chapter of the story in Onimusha: Way of the Sword. It begins at the end of Shadows Fall, after sealing the Rifts in southwestern and southeastern Kyoto. As usual, throughout this spoiler-free walkthrough we'll help you complete every story chapter 100%, making sure you don't miss anything along the way and providing tips for the more difficult situations.
First of all, if you've been following this walkthrough, you'll begin in the southeastern corner of Kyoto. Sealing the Rift will have removed a Malice Barrier, allowing you to collect Kyoto Treasure #45. It contains the Firebird Flute, a new Oni Armament.
This time, there's no new optional content to complete, aside from practicing with the Firebird Flute at the Practice Ground, so head to Rokudo-chinnoji Temple and speak with Takamura.
Ever wonder why, after every previous boss, we returned to the battlefield to find an Oni Glyph containing information about them, but we never did that with Ifuu? Well, here's your answer. Return to Kennin-ji by following the objective marker and make your way inside. In the courtyard, you'll need to seal a Rift. Nothing too unusual at this point. Well, technically it's a Rift from another world, but you know what we mean. Deal with it, enter the temple and prepare to face Burai, Lightning Keeper.
Leave Kennin-ji to trigger a cutscene and complete the mission. You'll then move on to To Live is to Suffer.
