there would be nothing and I mean NOTHING left of tanjiro. Doomguy's speed and strength alone are more than enough for him to go toe to toe with Kratos. add to that the fact he's been killing demons in hell, on Mars, and Earth since the original DOOM from '93 he's got more demons under his belt that Dante, Lady, Trish, Vergil, and Nero combined. and then there's his arsenal. his bare hands alone and feared but the BFG 9, 000? yeah this fight is the equivalent of a mouse trying to fight a titan. if anything Doomguy would let him live until he saw neziko. and before anyone says nezeko could fight him.... Doomguy or doomslayer as the new games call him killed the icon of sin twice, and the devil in the Doom Eternal DLC. not a snowball's chance in hell is anyone from Demon Slayer putting a scratch on Doomguy. now characters from Devil may cry or even Bayonetta (same universe If I remember correctly) they'd last longer but still loose.

Puttin DS against anyone that isn’t immortal or godlike isn’t even fair lmao
