Manga Abracadabr-aster!
High school student, the Assistant, is made to attend a club due to club regulations. While looking for a potential club, he comes upon one dedicated to stage magic where he then meets Sempai who unfortunately has crippling stage fright that causes her to mess up the performance continuously. Then to add onto that, you have a street performer going by the name "Saki-chan" who tried to usurp the magic club, and she also has some...interests in her brother. Yeah, it's that kind of anime.
There's nothing much to the show. As an ecchi, the main jokes revolve around Sempai finding herself in compromising positions such as getting tied up; having her clothes get damaged; or in one instance, forgetting to bring clothes to dress into as part of one of her street performances. That kind of humor gets really old because of how predicatble it can be. Going onto animation, it's average. Honestly because of the many pantyshots and boob bouncing, it almost becomes bland as it happens in nearly every episode. The opening and ending themes are decent as is the voice acting. There is a small number of characters in the series with each varying in terms of how they are played. The Assistant is generic and mostly serves as the stand-in for the audience observing Sempai's misadventures. He is the straight man of the relationship, but at the same time, I found myself slightly disliking him because of the fact that he makes it clear often that he is largely interested in Sempai for her breasts and her other attributes. The sixth episode in particular has him take advantage of hypnotism to get Sempai to do whatever he wanted. A really shallow guy that is.
Sempai is funny with her stage fright, but this also tends to get in the way. She is greatly passionate about magic, which isn't bad...but whenever she tries to recruit new members to the club, she comes off as annoying. Especially because there is no sign of her getting over her stage fright. It is something that continually gets in the way of progress. I understand that's a part of the joke — she performs better when she isn't in front of anyone else — but it quickly stops being funny quickly.
Saki is a big-breasted gyaru girl who does street performances. From the looks of it, she seems that she'll be set up as a rival of Sempai's. There's nothing to her aside from the fact that she has a disturbing crush on her obese little brother. Just her practically foaming from the mouth when thinking about her brother is unsettling. Then there is Sempai's older sister...Sister....who is an airhead who loves to tease her little sister and offers to be the Magic Club's advisor (she's mdoerately a good character), and Madara who is the club president of the Chemistry Club who takes a disliking for Sempai to the point that she loathed having the scientific tricks she does be equated to the stage magic that Sempai does. For the most part, all the characters are defined by one trait no more, no less.
Overall, Magical Sempai is a slightly below average series that if you love ecchi humor, I'm positive you'll have a good time with this one. Each episode is comprised of small segments that run for 12 minutes, so it's not too much of a burden to watch. But know that you are getting exactly what you'd expect.
Manga Bog-standard comedy anime
While some franchises are guilty of being drawn out for as long as their creators can milk them, the viability of an idea can be measured by how long you can keep writing about it before it starts getting stale. As such, it's very telling that Magical Sempai doesn't even finish a 12-Episode Anime (with episodes at half the usual length) before running out of steam.
The anime is about an unnamed student, known only as "Assistant" who joins a magic club with a sole member- the eponymous Sempai. Sempai is good at magic, but only when no one's watching. When she performs in front of others, she fails spectacularly, and often ends up in compromising positions. Will she ever overcome this and become a good magician?
The answer, unfortunately, is no. Since these comedic mishaps are the source of much of the anime's comedy, if Sempai ever got over her stage fright, the source of jokes would promptly dry up. As such, the characters are not allowed to develop or grow in any meaningful fashion.
This wouldn't be so much of a problem if the characters were at all likeable. Sempai's immaturity and bullheaded drive to prove herself end up making her fairly obnoxious, while Assistant's apathy does little to make him sympathetic. A sibling duo of recurring characters adds little to the cast, since they don't have all that much synergy with the leads. Out of the main cast, Sempai's older sister and the chemistry club president seem like the best characters, with the former being a loving but embarrassing big sister, and the latter being a well-adjusted science nerd who knows about magic-like science tricks, but aren't utilized very much.
Another downside is that the fanservice is rather excessive and in-your-face, particularly whenever Sempai's latest mistake results in a panty shot, her clothes getting wet, her ending up naked or all sorts of other things.
In short, there is very little reason to watch Magical Sempai, not when there are many far more appealing comedy anime out there, so I would not recommend doing so.
