Anime Multiverse: Starting by Teaming Up with Maple, the Shield Girl!

Synopsis: Seito had lived in a slice-of-life crossover world for seventeen years. During that time, he worked hard, built a stable life, and quietly hoped to settle down someday. Everything changed with the release of the world’s first full-dive virtual reality game. From that moment on, the world began to feel subtly—but unmistakably—wrong. By closely studying the playstyle of the so-called “Lucky Shield Girl,” Seito rapidly climbed the rankings and soon stood at the very top. Maple Honjō: “Seito-kun is amazing~! I love teaming up with Seito-kun the most~!” Shizuka Hiratsuka: “Hey, brat. Come over to my place tonight.” Kaguya Shinomiya: “Unbelievable! Losing to someone like him?! I refuse to accept it!” Yukino Yukinoshita: “Hmph. As if I’d ever like someone like him.” Utaha Kasumigaoka: “As expected of you~ That really was impressive~” As time passed, the line between the virtual world and reality began to blur. When the game finally fused with the real world, Seito—the first player to reach the summit—rose above everyone else and became the first god of this new era. …… This novel is a crossover featuring worlds from Oregairu, Saekano, Kaguya-sama: Love Is War, BOFURI, and more. — Description from novelcodex.org
