Honestly, this is the perfect end for this Manga. Everyone got what they wanted in the end, of course it still feels bitter sweet, especially for J but the dude wanted exactly this ending for himself and lived a veeery long life to begin with. For a dark and brutal plot about demons who live in hell and are gruesome in every way, the ending was actually very happy and logical. Loved it.
