Yeah, i wanna see my mage using Tanjiro's Yakuta so bad!! Demon Slayer makes the very best crossover for this game!!
Warrior>Uzui,Kokushibo,
Rogue>Nezuko.
Mage>Tanjiro or probably Nezuko(becos mage is smol)

One more, we need Madara&Hashirama's Samurai Armor Sets!!(Night/Day Blossom kinda good but yeah)
