This indeed is an eye-catching anime among the others. Anime fully animated by CG?! Yes. And it does its job well unlike other shitty CG animations. Not only the animation, but the story, characters and the VAs are top notch. This really is a "gem" ( ͡° ͜ʖ ͡°) among the ocean of anime ( Oh god the puns....) And this definitely is my anime of the year 2017 and here's why.
Story (9/10)The story setting itself was intriguing. People made of gems? No humans? and there is a lot more. It was just done brilliantly. Your brain will be constantly on the work decrypting the possible paths the story can go and how interesting it would be if it did. And believe me, the story won't fail to amaze you. The first episode will keep you hooked till the last. Every episodes ends in a cliffhanger teasing you to watch the next episode. And the cliffhanger won't be disappointing you in the next episode, since they really matter and bring a lot of change to the story. In overall, the story part was really great and well done.
Animation (10/10)Now lets see.... CG animation is not very welcome in the anime world. But some anime has tried and have taken the risk, which mostly ends up in a failure (Talking about berserk here, and any other shitty CGs). It's mostly because that the CG animation was unnecessary for those kind of anime, or else the moments were too stiff and weird for the standard 2D anime audience. But Land of the lustrous has brilliantly used the CG animation for themselves. Taking up the CG animation, in my opinion, a good choice for this anime. It's because a lot of things in this anime cannot be animated normally by 2D animation. There are too much refractions of light in the characters hair (Especially Dia, just wow her hair is awesome) ( and there is Sensi..... One last man). Also, not only the fight scenes, every normal moment is precise and smooth to the extreme. The cameras are angled in such a way that they can cover everything around the scene and not miss even the slightest detail. Not only the necessary characters in the frame, but even the ones not focused for the scene are animated smoothly (they just dont stand there, they move) and this will keep you entertained and not get you bored of the scenes. There is always something to notice, whether it be Dia acting cute or some crucial element related to the story. And the camera moments are just wow... Done to the point that you feel you are actually playing a game on 120 fps. Even the grass is animated beautifully, you can never see such an awesome grass animation in any other anime. The backgrounds are hand drawn, but in such a way that they would suit the CG animation and won't feel out of the place. They were beautifully combined like an alloy ( ͡° ͜ʖ ͡°).There are more to talk about animation and I can go on and go on. There are no mistakes in the animation, and i feel that it was a right choice made by them by choosing CG.
TL;DR : you wont be disappointed from the CG of this anime.
Sound (8/10)Just like the story and the animation, they did an excellent job on this part too. The BGMs really matched the scenes and the overall settings of the anime. They are sometimes calm when they need to be, humorous, and heart throbbing when they need to be (during the fights). The VAs did an excellent job, and their voices really matched the characters and their personalities. Heck, the way the characters speaks (talking about their tone) changes as some of them go under drastic changes. It was just, great.
Characters (8/10)Every characters are unique and always interesting in some point. Some are funny , some are calm and they all have unique characteristics (or should i say, chemical properties?) which can be fun to know about. Some characters also undergo drastic changes which keeps the story on the pace. The characters were really memorable, cute and adorable. (Hugging them would be "hard" ( ͡° ͜ʖ ͡°) ).
Overall (8.8/10)I would highly suggest you give this a try. If you like something interesting, if you are familiar with CG animation and if you like chemistry of minerals, then you should give this a try. Even if you hate CGs, just give this a try, this is CG animation taken to a whole new level. Everyone should try this anime! You might like it you know! This will really "reflect" on you ( ͡° ͜ʖ ͡°). I just love the community made puns, they really make me "crack" into laughter ( ͡° ͜ʖ ͡°) .
