I focus my reviews around three main aspects: art, characters, and plot. In question form: "Is this visually pleasing?", "Do the characters invoke an emotion in me (e.g. like, hate, adore)" and "If someone asked, would I say the story holds its own?"

I'll do my best to put all major spoilers in tags, but be wary that minor/general spoilers may be present.

All sections have a tl;dr at the bottom.

Art

• 6/10 (animation)
• 7.5/10 (characters)
• 7/10 (effects)

If you like fan service, you'll love this anime. It has an excessive amount of raw nudity and all the usual fan service bits. I'm not a huge fan so I found it a tiny bit annoying, but Arata's reactions to each bit was great so I actually found the fan service to be a positive aspect here.

The animation (not the art) was pretty shoddy, I won't lie. However, I do have a weak side for aesthetically pleasing characters. Lilith, Yui and the Sherlock twins were stellar. The rest weren't bad (other than Akio, which I didn't feel particularly strong about).

Since this is a magic anime, the effects are also quite an important part of the show. They weren't outstanding, but it certainly wasn't anywhere near as bad as the animation may lead it to seem they may be.

tl;dr - "Is this visually pleasing?" - Yeah, if you like excessive fanservice (with a MC that doesn't have cliche reactions), good character visuals, and magic.

Characters - 8/10

Definitely the strong point in this show by far.

Arata - Pretty standard harem MC, honestly. The one thing that sells him for me is his reactions to the various fan service bits, which are far from the stereotypical MC reactions. Plus, he's OP, so that's fun.

Now, since this is a harem anime, I'll go in order of my favorite to least favorite

Yui - Both of her forms top the looks chart for the characters. Aggressive in love, but caring towards her friends. Probably plays a killer Yuumi too.

Lilith - I mostly love this character for a combination of her looks and the gap between her and rest of the casts' reactions to being fan-service'd (most of the cast doesn't seem to care, or invites it), but Lilith reacts pretty much as you expect her to.

Sherlock Twins - A classic example of abusing gap moe, but there's a reason why it's such a well known thing. It works.

Nothing big to comment on the rest of the cast, overall good characters and each have their own quirk they bring to the table, hoping to appeal to as many viewers as possible.

tl;dr "Do the characters invoke an emotion in me?" - Yeah, but not by their own individuality, most of the emotions invoked as a result of pair dynamic and gaps between one another. If you isolated each of the characters, only Arata and Yui may be worth their salt. Which is fine, but it keeps me from any higher than an 8.

Plot - 5/10

The weakest link. I'd imagine anyone who completed the anime can agree this is the case, at least for the anime adaption. Things felt really rushed, as there really were no good conclusion points except for where ended up, especially if they didn't know if they had the budget for a season 2.

Plus, not even the story took itself seriously, but that's an intended result by virtue of the type of story it tells. I don't think the author wanted the plot to be taken seriously, or else we wouldn't have the absurd fan-service, randomly OP MC, people kind of leisurely chatting within a couple feet of each other in a life-or-death battle, etc etc.

So, I don't take away much from my rating because of the plot, just because the plot was built this way (or so it seemed from what we've seen adapted)

tl;dr "If someone asked, would I say the story holds its own?" - no, it's a mess of cliche or over-the-top bits that were feel intended to make the plot less important, which is fine, just don't go in expecting a Kimi no Na wa story to unfold.

Overall - 7/10

If you like the magic genre, you'll like it. If you like harem animes, you'll like it. If you enjoy fan service, you'll love it (joking, sort of).

If you like none of those, I don't recommend it. The characters are great, but they're not worth the downsides if you aren't into at least one of the three bits above.

But if you are in one of those three, it's a pretty enjoyable watch. You can't take it seriously, but as long as you know that you can expect something worth watching.
