this had me wondering too....
I’m pretty sure he can exchange skills too so if he wanted he would just get rid of that skill and change its to something else, then die I guess ╮(￣▽￣)╭
Well, he can stab himself then go back to few years back....
I'm sure he could probably find a way lol. As a main character, he'd probably make some sort of wish to a goddess or angel to die. Or maybe at some point, after climbing the tower he gets like a gift of youth (until he dies) and therefore dying of old age wont be a problem. Maybe he himself will become some type of god anyway. Either way, he's a hack, so he would find a way XD
So I was just wondering... he's technically an immortal right? What happens when he dies of old age? He's forever stuck at the day before he dies then?
