Rentarou introduces Mei to the harem, and Hahari provides maid uniforms for all the girls. After a few minutes of fun, Hahari proposes a water gun battle, with the winner getting a kiss from Rentarou. Mei makes preparations, and Rentarou is provided with a butler's uniform to serve as referee.
Mei proves fully adapt at dodging the blasts, and Karane succeeds in dodging her blasts. After some teasing from Hakari, Karaneis eliminated by Kusuri, who in turn is eliminated by Nano. Kurumi attempts to get a shot on Hahari, who is captivated by the sight of the soaking wet maids, but Hahari quickly turns the tables by tossing an anpan, allowing her to eliminate Kurumi. Nano attempts to approach Hahari, but gets stopped by Mei. After a brief shootout, Nano opts to target Shizuka, whose random blasting eliminates them both.
Just as Mei is about to triumph, Hakari takes her mother hostage and orders Mei to eliminate herself. Before she can comply, however, Hahari stops her by shooting herself in the head. Mei immediately exacts revenge on Hakari before embracing Hahari, resulting in everyone getting wet. Rentarou, however, declares everyone the winner, and as a result of the ensuing barrage of kisses, ends up soaked as well.
And the Hanazonos manage to get even wetter than they already were.
Tropes:
- Lame Pun Reaction: The ending joke gets called out by the God of Love.
- Making the Choice for You: Hahari frees Mei from being forced to eliminate herself by eliminating herself.
- Pre-Mortem One-Liner: Played for Laughs when Nano prepares to eliminate Shizuka."Sayonara, Yoshimoto Shizuka."
