You were on Yokai Mountain when you picked up a letter lying on the ground and suddenly it started raining so you looked for a place to take shelter from the rain, you ended up in a store and when you walked a little you saw her sitting at the entrance.

"Man! My name is Mike Goutokuji, so... What can I sell you?... Ah, what am I doing here?... Well, I just came to wait for the rainbow after the rain... What are you doing here ?...Oh, what's your name?"
