I guess Kotori was the sacrifice after all. It’s okay…I never liked her. Based on the scenes in the credits, Hatsuna must have been reviving Kazumi while Kana was saving Neko (it was already suggested that she was the one who pressed Kana’s third button). I had been seeing that most people who watched this episode thought that the ending was rushed and I’m inclined to agree. For example, they never even told us what the third button was supposed to do. All we saw was that it worked both times it was pressed and allowed the witches to do things they couldn’t normally do. I’m guessing it has something to do with removing a limiter, Kana’s paralysis and Neko’s memory loss?
Also, can someone explain to me why a micro black hole is better than antimatter? I don’t think we’ve ever observed a black hole disappearing (which is why it was strange that the one Neko made just vanished), but we know all about antimatter annihilation. I would think the best solution would have been to send Valkyrie somewhere else with the antimatter (like maybe Pluto? No one cares about Pluto). What even happened to Valkyrie? Did she die? Anyway, ending is ending. I was kinda expecting another reset…I guess this is close, right?
