It is Mother’s Day, but Koyomi finds himself alone at the park instead of at home. He notices what appears to be a young girl who needs directions, however she runs off before he can do anything. Hitagi then shows up, and Koyomi learns that this is the area she used to live in. Sitting down next to him, she brings up the topic of repaying him for how he helped her so that they can become friends on equal terms afterward. After much discussion of what Hitagi is willing to do, Koyomi brings up how he got into an argument with his sister over celebrating Mother’s Day. Unlike him, his sisters are close to their mother, and since he felt that he didn’t belong in his own home today, he got into an argument with Karen. Koyomi is frustrated with his small-mindedness, yet he doesn’t want to return home, and despite some teasing in regard to this, Hitagi vows not to abandon him. She even offers to help him if he wants a girlfriend, and though he considers it, he turns it all down.
The young girl, whose name tag reads Hachikuji Mayoi, then appears again looking lost, so Koyomi goes to talk to her. Mayoi, however, doesn’t want to talk to him and claims that she hates him. She ignores him when he attempts to talk to her again, so the third time, he smacks her against the wall. This doesn’t make her any more receptive to him, but she at least talks to him again and reiterates that she hates him. Their conversation ends up leading nowhere, and after Mayoi kicks him in the gut, Koyomi gets into a fight with her and briefly knocks her out. He laughs triumphantly until Hitagi shows up, and he tries to explain what’s going on and gets Hitagi to help Mayoi find the place she’s looking for. Since Hitagi doesn’t want to touch anything he’s touched, he reads her the address, and she knows the area well enough to be able to lead them in the right direction. Mayoi by now has regained consciousness, and Koyomi has convinced her that she had a dream that’s opposite of reality. She confuses him, however, by calling herself the lost child of the snail.
Despite being rather dialogue heavy – over sixteen straight minutes worth with no OP in between – this episode had a surprisingly large amount of good character/relationship development for Koyomi and Hitagi. I say “surprisingly” because I assumed that this arc would focus more on Mayoi and not quite so much on Hitagi. Not that what they did is a bad thing: this episode managed to be pretty amusing at times, like with the whole siscon and sorocon thing, and I even chuckled at Hitagi’s Dragonball reference when she was describing what she could do. Hitagi in general is just a lot of fun to watch when she’s driving Koyomi crazy and sort of flirting at the same time.
Admittedly though, the most interesting part of the episode was after all that, when Mayoi appeared the second time. I laughed when Koyomi suddenly smacked her, and their subsequent fight had a bit of a Scooby Doo quality to it, which made the fact that he fought a grade-schooler a little less awkward, but no less absurd. Mayoi herself is pretty cute, and Katou Emiri does a pretty good job with her voice. The question is what the snail has to do with her being lost, and I’m sure there’ll be some sort of wordplay behind it to explain it in the two remaining episodes of this story arc. Hopefully they’ll also show Koyomi using more of his vampire powers like he briefly did this episode with his eyes.
