[Anime Crossover] Shido Itsuka's Vacation

Synopsis: A new neighbor moved in next door, and suddenly the whole street came alive. On the first day, a stunning purple-haired girl knocked on the neighbor's door with a wounded look on her face. The Asahinas looked on with envy. On the second day, a wildly popular girl idol knocked on the neighbor's door, looking gloomy. The Asahinas stared back, completely bewildered. On the third day, a pair of beautiful twins with completely different styles knocked on the neighbor's door with red-rimmed eyes. The Asahinas looked on with reproach. On the fourth day, a cute little blue-haired girl with a soft, adorable look knocked on the neighbor's door, tears glistening in her eyes. The Asahinas looked at him like he was a pervert. On the fifth day, then the sixth... At last, they couldn't take it anymore. When a beautiful girl with short white hair came to knock, they stepped forward and made a tactful suggestion. The girl looked at them coldly. "It's fine. As long as Shido lets me stay by his side, I don't mind how many other people there are." The Asahinas: ... The Asahinas all said, "Sorry, boss. We didn't mean to bother you." But when they saw a cute girl with white ribbons tying her hair into twin tails standing outside the neighbor's door, covering her eyes as she cried, "Nii-san, does this mean you don't want Kotori anymore?" Tsubaki Asahina, who had no younger sister but somehow still had a brocon streak, couldn't hold back and charged into the kitchen. "Stop! Don't try to stop me! I'm grabbing a knife and going to butcher that beast next door!" Itsuka Shido: I'm not! I didn't! Don't make things up!
