Ok, what if Subaru died and was reincarnated as an Oni? I mean, it sounds pretty cool. And from the amount of pros it has, I'd say it's a pretty cool idea. Now for what Subaru would look like as an Oni.
Of course, he's have two horns instead of one but it still looks cool regardless. And the detail of his weapon looks clean as hell, I can just see him screaming "GET OVER HERE!".
Did I also mention that Subaru absolutely DESPISES the Witch Cult? And another thing, is it possible to make this dude have a gun? Or is it possible to even recreate a gun in the Re:zero world? I wanna give Subaru the ability to forge and make his own equipment and weapons. Lol
