Koharu (Sei Shiraishi) was told by Matsuko (Anna Ishii) "Don't trust the Girl Gun Lady", but Alice (Yuno Ohara) was a player of Alpha Tango in the past, Masami (Tomi). I will be told the story. The photo at that time on the album shows a battle method called "Plamode" that is unfamiliar to me, and when the girl gun lady and the player's hearts are united, Natsuna (Momoka Ito) activates it. Koharu hears from Akiho (Natsuki Deguchi) ...

On the other hand, Koharu is confused when he is consulted by the enemy team, Higashino (Momoko Tanabe) of Delta Tango, as "Rasuichi". Then, in the "Girl Gun Fight" that was greeted, while covering Natsuna of "Rasuichi", Kitamoto (Ai Mikami) and Higashino of Delta Tango chased after Alpha Tango, a strategy to get the flag, and it was extinct. In a desperate situation- !?

Koharu (Sei Shiraishi) heard from a health teacher, Moriyama (Masanari Wada), that there is a warehouse behind a mysterious antique shop. After consulting with Akiho (Natsuki Deguchi), she secretly infiltrates Natsuna (Momoka Ito), who is preparing for the national athletics competition. The two of them sneaked into the store, but as expected, the store manager (Gaku Hamada) found out, and the homeroom teacher Hoshimiya (Aya Asahina) also reported and apologized. The two thought that the secret of the Girl Gun Lady was in the warehouse, and suggested to Natsuna, "Let's break into the Girl Gun Fight." Then, I talk to Alice (Yuno Ohara) in a parallel world, but I can't find a way to open the "bilibili wall" that surrounds the school ... On the other hand, Matsuko (Anna Ishii) is not the commander Bianca (Rio Teramoto) of Bravo Tango, but for some reason Alice offers a consultation- !?

Koharu (Sei Shiraishi) and Akiho (Natsuki Deguchi) finally infiltrated the warehouse of an antique shop run by a mysterious store manager (Gaku Hamada). Inside, it was as wide as a spaceship, and it was a strange space where the players who died in "Girl Gun Fight" were lined up like stuffed animals. A light bullet was fired from behind Koharu and Akiho, who were angry, and Matsuko (Anna Ishii) was there. And Alice (Yuno Ohara) makes a certain decision ... Also, in the real world, the existence of Natsuna (Momoka Ito) was erased, and a sad reality awaited. Koharu goes to see the store manager with Akiho to check the warehouse, but the store's warehouse is just a storeroom, and the mystery only deepens.

On the other hand, in the parallel world, a new player will be added to Alpha Tango in place of Natsuna- !?
