In a parallel world where all the youthful school-life anime have come together, is it reasonable to spend all your time making video games instead of enjoying your youth and having fun at school? Absolutely.
Ye Wuhuan can't stand a world without great games like "Call of Duty", "Battlefield", "Monster Hunter", "Elden Ring", and so on. The gaming industry in this anime world is way too backward! He's going to single-handedly restore (rip off) video games to the level they had back on Earth!
...What? Why doesn't he date the anime beauties in this world, like Kasumigaoka, Mai Sakurajima, and Yukinoshita? Are you kidding? I'm going to be a legendary game developer. Women are a hassle!
(The story is split 30% romance and 70% game development.)
