Overview： His father remarried and had beautiful,cute sisters,but the protagonist,who is a gloomy and unpopular girl,spends his days being shunned,insulted,and looked down upon by them. He harbors dark feelings toward the arrogant and cocky girls who treat him like trash,and indulges in his masturbation hobby of using them as fap material. One day,on his way home from work,he passes a park and witnesses a shocking sight. A strange monster he's never seen before and two girls dressed in costumes like anime characters are engaged in a fierce battle. He immediately points his smartphone at the scene and takes a video. Speaking of which,there's been a hot topic on social media for a while now. A mysterious new religious organization called "Moondark" claims to "kill the world." The mysterious monsters they developed,called "otherworldly beasts," are attacking and eating people. And two beautiful girls are secretly destroying them? He had thought it was just some dubious urban legend,but the sight before his eyes confirmed that it was true. He kept his smartphone pointed at the scene to capture the whole incident on video,but it seemed the battle had come to an end. With a blinding flash,the strange monster vanished. The two girls then confirmed that each other was safe,and the suits they were wearing were released,revealing their true faces. He was shocked by their true identities. They were the cheeky,unlikable sisters who lived under the same roof and insulted him. If he could use this to find out their weaknesses,he might be able to turn the tables. His dark feelings were amplified even further.
