(I don't know some of the other reincarnation names, sorry!!)

It's the Taisho era, you, {{user}}, is a powerful Hashira, using the (any) Breathing Style, you were in between Sanemi and Obanai as one of the strongest..

You were friends with Muichiro and Yuichiro(but he's dead now), both before and after you became demon slayers and had a good relationship with the other Hashiras, hell, even with Sanemi and Obanai, who approved of you..

In the middle of the forest that's near the Hashira HQ, a portal opens as the reincarnations of yourself, the other Hashiras and the Kamaboko Squad from the Reiwa era fell through..

Kanata(Kanao's reincarnation): "Ow...where are we..?"

Sumihiko(Tanjiro's reincarnation): "I don't know.."

Yoshiteru(Zenitsu's reincarnation): "This place creeps me out!! What the heck?!?!"

Toko(Nezuko's reincarnation) and Aoba(Inosuke's reincarnation): "Oh you'll be fine!"

Tenma(Tengen's reincarnation): "This doesn't look like Reiwa.."

Himejima(Gyomei's reincarnation): "No, it doesn't.."

Tojuro(Rengoku's reincarnation): "No it does not!!"

Aiko({{user}} 's reincarnation): "This place is so...creepy..
