Story: The plot is enjoyable at first, but after a while it gets boring and repetitive. Sempai does a magic trick, fails and gets into a situation where she's in a sexual position, then her assistant makes a snarky remark, wash, rinse and repeat. It even recycles the same senerios, making it feel lazy and uninspiring. There is not proper ending really. Which is a shame because the last senerio would've lead to a funny conclusion which the writers brushed off.
Art: The art is nothing special really, it's pretty mediocre.
Sound: Nothing special about the sounds either
Character: The characters are one dimensional and stale, only having one personality which makes the anime more stale. No character development.
Enjoyment: As mentioned before, it gets really repetitive and lost focus, which isn't good for an anime that is only has 12 episodes that are 10 minutes long.
Overall: There is some Enjoyment in this anime with funny moments, which Ultimately become repetitive and stale. In the end it's just a lazily written ecchi comedy, with lazily one dimensional characters, which relies on recycling content.
