[Detective Conan] Kamen Rider in the World of the Great Detective

The day after he built a character for a power-gaming run, Yuki Rin transmigrated, and ended up as the very character he'd made.

Staring silently at himself in the mirror, he wished he could transmigrate back and bash his head in for piling on all those buffs when he built the character

That's what you get for making such a ridiculous build!

Theme: I think people should communicate with each other more kindly.
