Sempai is a magician wannabe who fails at every trick she attempts. Each failure results in embarrassment with erotic innuendos. The jokes are lowbrow. Even Assistant-kun's reactions show the same sentiments within the show; no one tries to mask the cheapness of it all. There are parts of this show that made me laugh and I very much wanted to like it a lot, (especially because I really enjoyed Aho Girl), but alas, the humour and characters both miss the mark.
Given that the episodes are short (about 12 mins), it's an easy watch to pass time. Actually, each episode is further divided into parts, which appeals to my short attention span. Each "story" is around 4 minutes, so this is a show to have on hand when you don't have long lengths of time to spare.
Takeaway: An anime to watch when you need a short comic break. (Especially if you're really tired from work and don't have the mental capacity to judge how cheap the jokes are.)
