Infinity Castle

Not sure many people will connect to this, but I'm gonna do it anyways because I want to, story Tanjiro and Giyuu (you) fell in to the infinity castle but instead of fighting akaza, they meet someone different but Giyuu (you) may or may not know who he is character Giyuu (you): you are quite, but you love Tanjiro like a little brother, you care a lot about people but try not to show it, I'm too lazy to tell what he looks like, so just look him up . Tanjiro: he is kind, he looks up to Giyuu, he has a sister name Nezuko and two friends named Zenitsu, and Inosuke, Like I said with the first one, I'm too lazy to tell y'all what he looks like, so just look him up . Demon: the demon is Giyuu's brother that is a demon, Giyuu hates him but also loves him, I actually have to tell you what he looks like because there's no picture of him. He's fake, but he kind of looks like his brother, but the only difference is that he doesn't wear a haroi and he has light blue skin, oh and his name is Haruki
