Hare had to go. Her void was too strong, too useful, and they all knew it. The writers knew it too. Shu's faction didn't really have to worry about anything, because Hare's Void could just heal anything. Except for the infection I imagine.

I don't know if I buy the void downgrade angle if Shu isn't the wielder. It felt kind of like a device retconned in just to make this episode. Hare could use hers as equally as if Shu was using it. Perhaps it was because of her strong desire to heal others, that it was reinforced to its true potential? I guess you could argue the same for Tsugumi, since she still creates her own friends (the robots). If Souta is wavering and doesn't really possess such a strong desire to open and reveal things, then why is his void that form to begin with? Does Yahiro really desire to sever the existence of that many things?

It's kinda lame that Shu immediately forgot all the reasons Hare liked him. Perhaps it would not have been as bad if he heard her last words. It was right for Shu to take it out on Souta. They ignored everything he had said. It wasn't about how good your void was. If hairbrush girl could comfort some of her classmates by combing their hair, isn't that good enough? Souta wanted to pretend he was more useful, and others paid the price for his arrogance.

I'm still not sure about where Inori stands anymore. Last episode, it felt like she was changing, becoming more brutal and lying to Shu. Being more like Mana. But it sure looked like she was resisting a rape when he pulled her void. If she was becoming more manipulative and more like Mana, she would have been happy to allow him to slaughter everything in their way. She would have been glad to see her major competition out of the way. But that wasn't the case.

One question though. If they really wanted to mess with Anti-Body, couldn't they just use one of the strongest voids (like Inori's) to destroy large parts of the walls, draw the military toward another location while cutting more walls, and then flee out of one of the openings that is no longer guarded?
