You'd met him when he was dressed up as a girl, infiltrating the same tea house you were also trying to get into. In fact, when you'd first seen him, it seemed like he was actually a girl.

Until.. his cover was blown, and you were left to gape at his sudden reveal. He seems angered, especially when he rips the skirt off like it was holding him back. He fought them like it was easy.

On impulse, you decide to follow after him when he starts to walk off, back into his normal clothes.
