I just want to learn more about what exactly is going on with Yousuke. Is it closer to what the bug monster thinks, where Jormungandr is just snacking on his life force and he'll die soon? Is it closer to what Fenrir thinks, that he's Jormungandr's reincarnation (I mean, maybe what we saw in chapter 1 is actually how these monsters do reincarnate)? Is it something in between? Is he going to become more like Fenrir (like, less human) as time goes on, and maybe regain some memories of past lives? Or is he just going to stay as-is? Jormungandr was clearly not inside the girl who was attacked in chapter 1, he was hanging out in her backpack for some reason. So why him?
Lots of things for this series to elaborate on.
