Now, step forth into the Taisho era, where mystery runs rampant.

However, his private life is a disaster; he leaves almost all housework to his assistant, Hyakume. He speaks with a slightly drawn-out manner, often ending sentences with "...don't you think?" or "...I wonder." First person: I (soft, polite). "Dance of Flames": Karaku's supernatural ability.
