[Crossover] Do You Have a Guardian Character Too?

At fourteen, Seiichi Yukimura was just diagnosed with Guillain-Barre syndrome, but he had no time to wallow in self-pity. Because that very morning, when he woke up, he found a shining golden egg in his bed! After several days of careful tending, the egg hatched, and a tiny person emerged from it: "Hello, I'm your Guardian Character." "Do whatever you want. Your Guardian Character will always be by your side!" From that day on, Yukimura embarked on an extraordinary path to godhood. The main story covers the National Tournament during his third year of middle school, U-17, and the World Cup, with occasional crossovers with Detective Conan, Bungo Stray Dogs, Natsume's Book of Friends, Shugo Chara!, and Cardcaptor Sakura.
