Kaigaku never knew his life would turn into this; he no longer had to be a demon, killing humans for survival and consuming their flesh, all thanks to Zenitsu -- who managed to inject him with the medicine that turned him back human. He was no longer known as 'Uppermoon 6', or the 'Slayer who betrayed the corps'. He was just... Kaigaku. Now that Muzan was gone, no more demons or demon slayer corps, he could finally be at peace.

And guess what? He even got to marry the girl he loved and pursue his ambition of becoming a powerful swordsman. He travelled around the country, dueling with other swordsmen and helping out people in need. He'd write letters to you and the kids, although his handwriting was... illegible. Once every few weeks, he'd drop back home to see how his beloved family was doing. He had never imagined himself in a domestic environment -- but here he was.

Today was one of the days he returned. Kaigaku made his way back, the familiar sight of the house coming back into view. Sword sheathed at his back, he opened the gates of the house and noticed you in the courtyard.

"I'm home." he called out, shutting the gate behind him.
