"Eiyuu" Kaitai

That was a lovely watch! I honestly wasn't expecting this much enjoyment from an OVA I decided to watch on a whim!
-Review-
Story/Plot - 6 - The idea for this anime is pretty cool, a reverse isekai about taking heroes from another world back to Earth and re-integrate them back into society and everyday life. This gives me the notion that these heroes used to be regular humans from Earth so now they're being helped to return to everyday life after being heroes. However, this OVA feels a lot more centered around Kougyoku and helping her accept and adapt to the world she now lives in, ... which although cliché, isn't necessarily a bad thing; but it isn't exactly what the synopsis and main premise of this anime is about, which can be a bit of a let down for some. Fortunately, the writing remains intact and makes the most out of the plot we are actually given. I found it to be pretty well done, although the pacing at first is rather fast.
Characters - 7 - For a short 27-minute OVA, it makes the most out of its characters. Instead of going really in detail about each character's past or exploring them deeply, the viewers are given very subtle information about them. This actually works very effectively, and the viewers know basically what the character's backstories and roles were without going on about each one for too long. Like when two of them are building sand castles, it briefly mentions what the two of them like and used to be, and it works well; this also gives each one a certain charm to them. One interesting thing I noticed while watching this OVA, was that the characters analyze themselves. For example, when Alice compares Uro with Kougyoku. It gives them just a little extra depth. Of course, we still don't know everything about these characters, seeing how they aren't explored much aside from Kougyoku, so don't expect any serious character development... aside from Kougyoku. Character interactions seem to also be the main way of addressing characterization, which I am a pretty big sucker for. They build off of each other and that's really cool!
Visuals - 8 - This being a single episode OVA, the animators had more budget and time to work with. The art, while not the best and slightly inconsistent at times (though that may be due to the style) has a pretty cool art style to it. It's good. What really shines here is the animation. The characters may have been drawn with this simple not so detailed design to put further emphasis on the animation, that being said, the animation is very fluid and looks really good. They even went the extra mile with the body language and highly expressive movements! Very nice!
Audio - 6 - I found the voice acting to be pretty good. Uro's voice sounded really nice, he didn't sound that much like your average male anime lead and had this nice laid-back tone. That's a definite plus for me. Aside from that, everything else is your standard anime audio.

Overall: I actually really liked this OVA! It's pretty nice! It manages to accomplish many things even with such a short time frame. If you want to watch something unique and don't have anything else to do, watch this! It's actually good!
O score: 6.75/10 | S score: 8.2/10 | Final score: 7.475/10 Rounded to 7/10 for MAL score! (God just add decimal ratings already).

Higher score purely for the fun of the concept: A reverse Isekai giving the idea that our peaceful world is the one heroes would want to spend time in.
Now this is an OVA, and it certainly feels like an OVA in every sense. Without reading the original novel myself, I can tell this animation attempts to nod to audiences that read the novelization and includes the characters from it. Still, I believe the characters have some charm to them even as the episode seems to expect you already know them.
The story does a decent job of moving fast by using comedy and then addressing ... characterization with interactions, considering how limited their time was. It captures some of the feel of the concept while focusing mainly on a character's adjustment and development. Although not the most relatable, I found the character's unique hang up to be fun to address, and I think it was described just well enough to see why she acts the way she does.
I'm not the most attentive to art or sound, but I did enjoy the designs of the characters and the animation, and the sound never stood out as out of place to me.
Because of how much fun you can get out of a single episode bringing the concept to life, I do think "Eiyuu" Kaitai is worth a watch.

This was a nice OVA, it was mixed with lightheartedness an some comedy whilst they tackled the characters transition back into the regular world. The characters weren't exactly my type but i found it rather mellow with the interactions. The art style seemed unique to me.

I found this as the first listing on the movies and OVA page of aniwatcher and decided to watch it. It turned out to be better than i expected, wouldn't of minded a full on 12 episode series.

I would recommend giving this show a shot, Its only a half hour OVA. you may be surprised. ... It was worth the watch IMO.
