is there any chance that the brother is still alive?

That's what i was thinking, but also, didn't the tower disappear after he defeated the 100th level boss? I'm not sure where he would've gone after that :(

Maybe it’s a situation like draw? Like a last desperate move where after the enemy defeated, the hero also died?
I also hope the brother is alive. But chances are tiny ╥﹏╥

They made him too handsome to just be a memory ;_;

loll but maybe he’ll just suddenly appear in a random dungeon idk
