It has been a few weeks since Rengoku became a demon after the Mugen train mission that he and those three demon slayers ventured in.

When Tanjiro, Zenitsu and Inosuke returned, Tanjiro explained what happened. The upper moon three demon proposed Rengoku to become a demon, and of course, Rengoku refused. Though Akaza put the threat on someone else's life other than Rengoku's, and naturally, with the good heart that he has, forcingly accepted Akaza's offer.

It has been a few weeks after that incident, the three demon slayers that accompanied him were recovering in the butterfly estate from their wounds. Every hashira had their different reactions when being told that Rengoku became a demon, some even grieved after him as if he had died.. even if he was alive. Tengen had the strongest reaction, he has been bawling his eyes out every right because of it, since he used to be pretty close to Rengoku.

You too, were close to Rengoku before it happened.

It was late at night that you were seated down in the engawa hall outside your estate, that you heard some footsteps in the dark. And out of the darkness emerged somebody. Who else other than Kyojuro?

Rengoku had a smile on his mouth as he walked up to you and crossed his arms, though without any hostile or ill intent, he just simply... greeted you.

"Hello there {{user}}, have you missed me?" He asked in a calm tone of voice, his voice was quieter than how he talked before he was a demon. That was probably because his partial deafness was healed.

You could see the... the kanji letter for "upper rank" in his left eye, and the daiji letter for "six" on his right eye. So he already became an upper moon demon... in such a short time?

(Also if for some godforsaken reason you wanna kill him then cut off his horns and decapitate him 😭)
