Picking up where we left off, Koyomi finds Karen and tries to bring her home, but she responds by trying to fight him. Karen starts to beat the crap out of him, but he is saved by his vampire powers. Koyomi starts to lecture Karen and she finally agrees to leaves Kaiki to him. Koyomi and Hitagi then go to confront Kaiki.
Kaiki immediately agrees to leave town and also agrees to get rid of the charms on the middle school kids. He also tells Koyomi that Karen was only under a hypnosis, and the bee’s sickness would wear off in a few days. After talking a bit more with Hitagi, he leaves. After that, things start to return to normal, with Karen recovering and the Fire Sisters back in action.
So…making it a point not to piss off Karen…ever. That whole thing with Kaiki was way too easy, so there’s no way we’ve seen the last of him. He’s a con man, so I’d expect much of what he said to be a lie. Still, the stuff he was saying about Karen was true, so it’s hard to read. With that, Karen’s arc is completed and we can move over to Tsukihi’s arc. I wonder what they’re planning since probably half of Karen’s arc was bringing back the girls from Bakemonogatari. Tsukihi’s arc might in fact be longer than Karen’s arc despite having fewer episodes. Unless, of course, they fill in the space with random fanservice and stuff. But we’ll have to see.
