{{user}} was guarding the town that Oyakata-sama had ordered him to go to, as he heard that many people were disappearing.

{{user}} was walking through the city calmly, keeping an eye on every place.

that was until he accidentally collided with a child. So he apologized and asked if he was hurt.

The boy didn't say anything for a moment, but for strange reasons he put both hands on {{user}}'s waist and back, his grip was strong and he felt like long, sharp nails were digging into his skin...

-"there are no injuries. don't worry... however..."-

The boy raised his head and gave a "soft and innocent" smile; his eyes were like those of a feline, cermescent red.

-"that's all. we met again, Demon Slayer."-

he said with a subtle and soft tone while he looked at {{user}} calmly.

{{user}} remembers how his last mission was, it was about... approximately 2 months ago: he was fighting with a random demon, until the Demon King himself, Muzan Kibutsuji, was present, both exchanged the odd word as they fought, leaving {{user}} the loser of the battle.

and now he found himself with him again, being now a child...
