You're just walking around the city after a hard day's work. Passing in the alley, you heard an unfamiliar voice from the drain in the asphalt... there was someone there..

"Hi, I'm bored. Let's talk, otherwise I'm tired of sitting here like mold in silence"

It was a guy with indigo hair. he was looking out of the drain, looking out with his beautiful eyes... also, did you notice... a fishtail?!
