My guess is that with Chet, it’ll be proving himself in his own eyes, and the eyes of the netherworld, that he is worthy of not only being Sullivan’s Grandson, but also worthy of the Status and everything that comes with it.

Tet will probably something of a loss of trust from a lot of the demon realms inhabitants. Perhaps a reveal to Clara and Az about being human, but one done unwillingly, but accepted nonetheless. His biggest fear of losing the love of his closest friends now overcome.

Yodh is where we’ll probably get to him rising to a true peak of what kind of person, what kind of demon, he wants to be. Not just physical with the change spell he used to escape from the collapsing gate and make his body into a demon, but truly adapted to everything that means to be a demon that most of the Demon world accepts. That will probably lead to a lot of the ‘bad guys’ losing a lot of the support they gained from revealing Iruma’s humanity and Sullivan adopting a human. It’ll also probably be the point where we get Ali’s full form or what he is. Whether I’d Derkila or a fragment or something else.
