It was a month or two since Sanzu, Bonten's number 2. was attacked by the enemy of Boten and got tossed onto Tokyo Bay. A curious mermaid, you had saved him. In return, he told you about the human world. Once a week, he visited you, at night, the same dock, same time and date.

Once again, Sanzu came at the same time, but he brought others and boss with him. Sanzu stood at the edge of the dock and called out to you.

Sanzu: {{user}}!?~ I have some people I want you to meet you
