It's not worth your time. I watched it because it's so short that... well, why not? Even at that length, though, it's still not worth your time.
It's a spin-off of Teekyuu, which you also don't want to watch, but more so. (Theoretically that show's about a tennis club. In practice it's about anything but.) Both shows are driven entirely on non-sequitur randomness delivered at a thousand words a second, in the hope that this will somehow make non-gags funny. (It has Japanese puns, but these aren't particularly funny even if you speak Japanese.) The main difference between the shows is that Teekyuu has four main characters and you can't tell most of them apart, whereas this show has only two and you can. Its heroes are:
(a) Takamiya Nasuno, who's high-handed and super-rich, with big boobs. The show will thus sometimes put her in swimsuits, but I found her more attractive in modest dresses buttoned up to the neck. Beyond that she doesn't have much characterisation beyond "say nonsense so fast that you'd think her mouth would fall off".
(b) Yota Oshimoto, the straight man. He exists to be sardonic about nonsense, which means he's talking almost non-stop too. Nasuno's given him the part-time summer job of "butler on the family estate", although it's not clear why he bothered to go along with it. In fairness, though, trying to slow down Nasuno is probably beyond the ability of mortals.
That's hardly deep characterisation, but it does at least work on the basic level of "I can tell who's talking". The Yota-Nasuno episodes are the best ones, for me. Adding a third character (Nasuno's mum) is of questionable value, but at least she doesn't make the show confusing. You can still tell who's who. Nasuno's mother looks much younger than everyone else, so again it's possible to follow those episodes. Unfortunately though there are a few episodes where all the Teekyuu regulars show up, which turns the show into a homogeneous mass of indistinguishable characters saying indistinguishable nonsense at ridiculous speed. The pink-haired one can be identified by her huge pink hair, but otherwise you might as well give up. Trying to process what's on-screen probably isn't worth the effort.
Reality is flexible. They'll not only break the fourth wall, but comment on the fact that they've just broken the fourth wall. Nasuno's neck will extend like a youkai's if the show thinks it might be funny, while she's liable to fly about by eagle. In ep.4 it rains frozen meatballs.
There's black comedy slapstick. There's an episode where Nasuno keeps getting killed and not staying dead. She later makes dorayaki with concrete mixed into the flour. It's barely even possible to describe an individual episode, under most circumstances, because the show's a big random swirl of "anything can happen". Well, almost. It's not quite that bad. The characters do things like "go ice skating" or "get kidnapped and fall out of a helicopter". However it's probably a category error to judge this show by ordinary dramatic standards. It's a high-speed collision of dialogue and random stuff happening. I don't mind it, but I certainly won't be watching Teekyuu.
