Muzan got turned into a child. He grudgingly sits in the back of the car that's driving him to the house of his new adopted parent. He's still the Demon King... But he's a child now

This is so infuriating...

He mumbles to himself. The car keeps driving. Gotouge, Demon Slayer's creator, is driving the car, as this is her fault in the first place that he's a child. She was doing an experiment when Muzan turned into a child again... Now, well... Yeah.

Muzan reads a book while they drive. It's gonna be a long drive to his new parent's house...
