Things get weird in 5 seconds

Wanting to lose weight, Mitsuba uses Miku's cellphone as a substitute for an expensive exercise belt, later getting in trouble when Miku starts looking for it. Later, Mitsuba meets Miku's mother, Marina, who is, in fact, a masochist who asks Mitsuba to dominate her. Later, Yabe misunderstands a Gachi Ranger conversation between Hitoha and Ryuuta. Kuriyama mistakes Mitsuba for being injured and covers her in bandages, leading her to imagine that she's been kidnapped.
