@Merkarion What you said is fine, but you were wrong in one thing, Isse has evolved and matured a lot throughout the series (both physically and psychologically), and he is no more "the classic underdog that needs near death experience to grow and would be many times death if not for Boobs. " Those moments were just chance and use of his new body (Technically immortal); but he is much more mature, determined and intelligent (in several aspects). Another thing you said was that: "That is the truth, even with many possibilities of his new body it did not change because issey is still issey ..." well, that's fake. Issei does not change because he needs more experience and improve more (Something that many people always tell him, in fact, even he is aware of this!), Not because he is "the foolish issei fool of the beginning". Obviously he will continue to be perverted, but even in that aspect he has evolved, several characters told him, even the same author says it !.
