Tsuujou Kougeki ga Zentai Kougeki de Ni-kai Kougeki no Okaasan wa Suki desu ka?

Synopsis

The party revives Shirase, who reveals the Empress, real name Kazuno, is suspected of cheating. Shirase offers to waive the fine if Wise can repair their relationship. Kazuno immediately starts a fight where she summons a white room. Masato realizes she is using a hacking tool. Kazuno reveals she plans to use it in the real world to hack her way to riches and power. Kazuno then refuses to listen to Wise as she is still angry. Mamako suddenly breaks into the room. Realizing Kazuno is a Sage like Wise, Masato uses one of Porta's tools to seal Kazuno's magic. Kazuno is overwhelmed and defeated, though Wise catches her before she hits the ground, begging for them to reconcile. Kazuno transforms back to her true form, only to immediately begin arguing with Wise. Shirase accepts this as them reconciling and clearing the game, allowing Kazuno to log out. However, Wise opts to stay with Masato, claiming she want to help the party for fun. The real world Shirase contacts them with a new quest to fix the problems the software writers cannot. Mamako is happy she can have normal conversations with Masato again.
