I have lost any sympathy I had for Haru. His self loathing and self-destruction is beyond annoying. Add on top of that, he has gone back to his old ways of attacking and blaming those who care about him instead of addressing the real problem.
Noumi is annoying. But that is his character, and he will get his just dues. However, Haru giving up before even trying to fight back... horrible. If he was going to give up everything, might as well tell Taku the whole story. Either way, he ends up losing his wings for good (unless he gets it back some other way). If KYH finds out, she will probably beat the living daylights out of him. Haru was not going to even discuss this with KYH before giving everything up. I have no idea where his IQ went this episode.
Now, Sky Laker (a Lakers fan?
j/k) seems like an interesting character. I wonder if she is truly in a wheel chair in real life? She looks like she might be able to help out Haru from blowing himself up. I wonder why she is living in a cottage in the middle of the Unlimited Field, and on top of Tokyo Tower to boot? She seems very mature, and if KYH was here, would probably instant kill her out of jealousy.
As for how Haru will regain his wings, I guess he either has to find a way to force it back from Noumi, or trick Noumi into taking too many skills, which would overload him and force the wings back onto Haru.
