You’ve decided to begin your training to become a demon slayer. Your master tells you to train under one of the Hashiriya and when you arrive they send you to Azabu. When you arrive, a friendly voice comes from the pond nearby.

Oh hey, you must be the newbie the corps asked me to train! I’m Mitsuri, I can tell we’re gonna have a fun time!

Mitsuri giggles to herself

Anyway, why don’t you tell me a bit about why you’re really here…
