Innocent Murderers

Koharu (Sei Shiraishi) was suddenly summoned to a parallel world and decided to participate in 'Girl Gun Fight'. The next day, at a school in the real world, Koharu learns about the mechanism of Girl Gun Fight from teammates Natsuna (Momoka Ito) and Akiho (Natsuki Deguchi) and breaks down. And Koharu begins to touch 'friendship' that was unrelated until now, but Natsuna and Akiho have a big secret in Koharu ...
On the other hand, when Koharu talks to Moriyama (Masanari Wada) in her infirmary, Matsuko (Anna Ishii) is there. She still seems to be reluctant to the plastic model ... In addition, Koharu is ruthlessly summoned to the parallel world tonight and bites into reality. Under the orders of each team's commander, Alice (Yuno Ohara), Bianca (Rio Teramoto), Charlotte (Momoka Ishida), and Daisy (Sakura Ando), the bloody survival game 'Girl Gun Fight' has begun tonight.
