Yeah, I haven't posted in a while. I suppose I am not good blogger material.
Anyhow, Kemeko DX is a comedy heavy anime that definitely does not take itself very seriously. It stars (kinda) Sanpeita, who's an unfortunate little kid, who in his childhood made a promise to marry a girl, who subsequently moved promising him to see him again in 10 years. 10 years later, he is having a normal morning when a spaceship crashes into the roof of his house followed by hostile robots from the local technology giant Mishima Co. But, out comes a short, fat, stocky woman with scary eyes and an extremely obnoxious personality to boot. comes and fights them all off with a weapon that's reminscent of a giant boxcutter blade. In the aftermath, she introduces herself as Kemeko and his wife, and adds that he is in danger, and that she will protect him.
Sanpeita will soon find he is roughly the only sane person that he knows. His family quickly accepts his intruding "wife", and when Kemeko replaces their homeroom teacher and also announces her identity as his wife, they are quick to accept the fact without much complaint.
This is somewhat similar to the situation of Sakura and Dokuro-chan in Bokusatsu Tenshi Dokuro-chan, and there's a lot of funny, absurd humour.
Sanpeita also has a childhood friend, Izumi, who is of the rather usual fare: likes him, denies it, and sees Kemeko (her rival) as an enemy.
It is quickly revealed though, that Kemeko is actually a very small robot or mecha, and is actually piloted by a girl (and this is also observable in the OP) who has a striking resemblance to the girl that Sanpeita promised his hand to. When asked though, this girl denies it being her vehemently, and Sanpeita decides that such a brash girl couldn't possibly be that girl of his dreams all those years ago.
As a note of warning though, this girl seldom comes out of her robot, and has a very deep emotional link to her power suit, Kemeko. Seeing M.M. in the flesh is, thus far, a rare pleasure.
Anyhow, Kemeko DX has been a very enjoyable, hilarious anime, and there are a number of very likable characters (along with often excellent character design, though Izumi's design is fairly awkward). The overall mood and tone of the story can pretty much be summarized by its ED and OP. I reccommend it to anyone who can tolerate silliness and absurdity, but people looking for a gritty, serious story obviously need to look elsewhere. Here are a couple of visuals to aid your decision, along with the aforementioned OP and ED.
