Mahoromatic: Automatic Maiden, Volume 2

Suguru, Mahoro, and company enjoy a wonderful beach excursion when their gleeful romping is suddenly jarred by a giant crab robot that emerges from the ocean. The robot, Cloud Crab, was designed originally by Saint to fight androids, but for some reason now seems to content itself by tearing off girls' swimsuits. Unable to forgive the robot for ruining everyone's fun, Mahoro vows to destroy it.
