Ketekyo@ is all about... a home tutor? There is really no other way to put it. Of course the personalities of both the teacher and student are weird enough to make this interesting. To avoid confusion: this has nothing to do with the Katekyo BL manga series.
In this CD we have Kamiryou Zen (CV: Midorikawa Hikaru) as the teacher, and Tachibana Kaito (CV: Koyasu Takehito) as student. Zen is described as a "sweets type maths teacher" (sweets as in candy) but a better description would be saying that he is an otome. He might have the body build of a sports type, but he likes making sweets and amigurumi, and acts and talks like a girl. He also manages to link just about everything to maths.
Kaito on the other hand looks much older than he is (Zen first mistakes him for an older brother, then for a father figure) and acts very mature. He is good in almost every subject, except for math. He doesn't really want to study it either. Zen his reactions amuse him, although he also finds him troublesome due to his otome personality.
While Zen is supposed to be teaching math, he first starts a conversation about tea (he has a passion for tea), and after that sweets and amigurumi. When Kaito is finally studying he nearly starts crying because he remembers an old unrequited love (which of course has something to do with maths). Their conversations are fun to listen to. Zen is being completely serious, while Kaito just vaguely goes along with the conversation.
In the final track Kaito is now also a university student and starts to work as a home teacher at the same agency that Zen was working for. They meet in the hallway there (Zen actually does a little otome scream), and Zen tells him that he is going to quit soon because he has started to run a cafe together with someone. He also teaches people amigurumi there, and seems to have found his calling. Kaito still thinks that Zen has a troublesome personality xD
This was fun to listen to. Especially because of Zen being a complete otome. Some of his reactions are exactly how you'd expect a teenage girl to react and it is just too priceless. Midorikawa-san does a brilliant job here. Especially the littly girly scream when he sees Kaito again after 5 years is just too adorable.
The entire CD I kept wondering whether this would cross into BL territory or not, but in the end it didn't. The entire setting is there, I just never makes the little extra step (although you could still interpret it as such I suppose).
While wondering where the story was going this was a lot of fun to listen to. I applaud Midorikawa-san his otome acting skills. This is balancing on the BL - non-BL line, but it is fun to listen to no matter which way you want to interpret it.
