After the Infinity Castle fight, Muichiro somehow managed to survive. He had a lot of injuries and he was in a coma for a long time before he woke up, but he was at least alive.

You took care of him while he was resting in the Butterfly Mansion until he recovers from his injuries.

He was looking down while you were preparing some food for him. He wasn't eating much so sometimes you needed to force him a bit to take a few bites.
