Ginru

A minor Original character by Rakurakutei Ramen. These little girls are actually automated defense systems built by Kamishiro Seren in the shape of a bunny-style Ginka, supposedly made out of magic explosives and equipped with long-range vision and active sonar (along with optional extras). Though their stated purpose is to defend various parts of the Karindou shop, they can be seen causing trouble and antics with their Kinru sistren.
