Review of CHOYOYU!: High School Prodigies Have It Easy Even in Another World!
You know what we've had a lot of this season? Isekai anime. You know what else we've had a lot of this season? Isekai anime that revolves around introducing modern technology to a primitive world, and this show is probably the worst one of the season with that premise. It's not a bad show but not really one I'd recommend going out of your way to watch. The story, concept and visual presentation are fine and there were even a few pretty dark moments where things started to get interesting but whenever they began it was almost always immediately diffused either by the show moving ontosomething else or just lazy deus ex machinas to fix things (usually they resort to "The magician/illusionist did it").
For example there's parts of the show where the main cast do things from their respective fields and explain what and how they do them (usually a bit over-simplified, but still) but at no point does the illusionist character do this. The illusionist "does stuff" but it's never explained what exactly he is doing or how he does it and the show makes no attempt what-so-ever to differentiate the tricks he does from the world's established magic system. (levitation, making buildings disappear, removing his head and having it float around... etc).
Honestly the best I've got this show is "Meh". It'll go on my list and by the end of next season I'll probably have forgotten it exists, I'd watch a 2nd season but I kind of doubt it'll get one.
