I got lazy, I will probably update/improve it. You as shown, start as Tanjiro, once you reach the Hashira level, you can switch between Tanjiro and Giyu. Also reasonable prices below. Water Breathing: 100 Blood Demon Art: 150 You Can Get A Tsuguko: 200(But it would be weird if you were a Tsuguko and you got this thing.) Hinokami Kagura: 250
It sucks but its got Mizunoto → Mizunoe → Kanoto → Kanoe → Tsuchinoto → Tsuchinoe → Hinoto → Hinoe → Kinoto → Kinoe+ Tsuguko and Hashira. Credit to the demon slayer wiki for the ranking system. Sorry but your yen is your rank. Also tell me if there is anything wrong, but also read the instructions before you say anything. BTW once you're the Hashira you are OP.
