Anime Crossover: From the Start, a Shut-In Angel, Then Megumi Kato

After transmigrating into an Anime Crossover world, Jiang Zhou only wanted to quietly live the life of an ordinary high school student. That was until a radiant, golden-haired honor student moved in next door “My name is Tenma Gabriel White. My dream is to make the whole world happy.” But fate's tricks had only just begun On a cherry-blossom-lined slope, a white beret came fluttering down. The moment he reached out and caught it, he met a pair of clear eyes that somehow seemed to fade into the background. “Thank you, Jiang Zhou... You still remember me?” Looking at Kato Megumi, who seemed to have a “background character aura,” Jiang Zhou finally realized: Why did the beautiful girls in this world keep barging into his daily life in such strange ways? Even more absurdly, the System only showed up at this point [Ding! Skill “Observation Haki” loaded: You can hear every little sound from the angel next door gaming all night, crystal clear.] [Ding! Skill “Perfect Memory” activated: Light novels? Manga? I'm taking every money-making opportunity this life has to offer!] Gabriel crouched by the door with her laptop. “Jiang Zhou, could I... borrow your Wi-Fi password?” Kato Megumi tilted her head and gazed at him. “I feel like you're more interesting than the ‘protagonist.’” Hiratsuka Shizuka pressed her iron fist to his forehead. “You brat! If you don't join a club today, you won't make it out of this office alive!” Yukinoshita Yukino pushed open the Service Club door. “I hear you can solve ‘interpersonal problems’ here?” (An Anime Crossover world combining elements from Gabriel DropOut, Saekano, My Teen Romantic Comedy SNAFU, Kaguya-sama: Love Is War, and more.)
