The idea of this show is funnier than its actual episodes, unfortunately. However that idea is very, very funny and it's still quite entertaining.
Kogarashi is the maid of Naeka Fujiwara. Naeka's grandfather insisted. However Kogarashi is a massive freak with glowing eyes, shark teeth and the voice of a supervillain. He's like every action movie baddie ever, compressed into a single sociopath. He has 37 senses, X-ray vision, prehensile enemy-capturing hair and is almost completely unkillable. He's a ninja, bodyguard, former maths lecturer at MIT... and a top-class maid. In a dress and a frilly mask.
Needless to say, having Kogarashi as a maid is a bit of a problem. He's capable of attacking random passers-by because they might have been assassins. He's gloatingly uninterested in concepts like "restraint", "personal space" and "normal civilised behaviour". If nothing else, he never seems to realise that women might object to being scanned with X-ray vision and then having their underwear criticised.
Kogarashi isn't Naeka's only maid, incidentally. There's also Fubuki, an ordinary human who's modest, elegant and quick to get out a baseball bat with nails in. She and Naeka will beat Kogarashi to a bloody twitching mess if he does something particularly bad, which happens frequently. Kogarashi doesn't seem to mind, or indeed notice.
That's a brilliant concept. I could watch a show like that for ever and indeed the manga ran for fourteen volumes and six years (2004-2010). However in practice, the actual episodes are less distinctive, being mostly about breasts.
You see, Naeka has big boobs. Fubuki does too, although she doesn't like attention being drawn to this. Five of the thirteen episode titles include the words "breasts" or "cleavage". Ep.2 suggests that Naeka's bad at maths because her boobs are depriving her brain of nutrients. There's a Naeka's Boobs Fan Club (three members) and a girl who's in drooling lesbian lust with her. Almost all male characters (except Kogarashi) seem obsessed with boobs, including (in ep.10) God himself. Yes, that's right. God is a sexist pervert and a cheat whose favourite things are female nudity and panty shots. (In fairness, the tennis game they hold for God's amusement is actually quite funny.)
In fairness, this tends to turn the men into jokes and/or punching bags. Most of this show's important characters are female and in no mood to take any nonsense. However the show had all kinds of story options that were mostly not taken. Naeka (and her brother) are the heirs to a fortune, in a family where one's rival heirs have a minimal life expectancy. (That's why grandad has ninja maids.) An ongoing villain is introduced in ep.12, only to escape at the end, vowing to return... but of course he never will. Had the studio been expecting to make a second season?
Similarly, storylines aren't built around Kobayashi as much as I'd expected. Naeka will get involved in something, often breast-related, and after a while Kobayashi will pop up to offer unhelpful help. This is quite good. It's often funny. However it means that these are usually Naeka-centred stories with Kobayashi being weird on the side. I like Naeka, but she's hardly the show's most extreme character.
Is it a good show? Yes, but a slightly disappointing one. It's fun, but more generic than I'd expected. There are lots of anime about schoolgirls with big boobs. There aren't many with a Maid Guy... but he's still pretty awesome. Maid Guy Healing Dance!
