Terrorizing people at the beach

Kafuru loves the beach, and she goes to the nearest one to her on a regular basis as a result. It's where she met her friend and attack dolphin, Luka, and it allows her the chance to get some fresh air and some time from being a miko, not that even her sisters really have the general vibes of being a miko either since one's stupid and likes explosives and the other is tomboyish and abrasive. Being able to wear things that show off her figure and make her look more like the adult she claims to be also helps, and she seems to have a decent assortment of bikinis to go with it, and her school one-piece but she never wears that around outside of school anyway.

Before this upcoming trip though, she was told by Haruka that there was gonna be a water gun fight and the goal is to be the last one with clothes on. The night before she heads over to where Haruka is and gets her water guns filled up with the concoction Haruka made to make women's swimsuits disappear.
