I think this one is better
eh, sorta. though there are some differences. the one with the mark on his hand was an actual reincarnation while this is more soul transplanting and suspended animation mixed together. also the guy with the hand mark is a battle junkie and this guy is more or less indifferent.
but i agree there are many similarities.

Hmm, it's the same principle as that one manga about a reincarnated guy with a mark on his hand, just worse ┑(￣Д ￣)┍
