Don't judge a book by its cover and Don't judge an anime by its cover

for the first time, we have an anime about space that doesn't have any mecha in the story, we have a crew of teenagers that we will learn their background through the story, there are no holes in the story, and it's a good point in an anime because you won't get lost, the story is mysteries, action, and sci-fi I loved it since the quality was perfect

the animation looks fascinating, the environment design  10/10, creature design 9/10, character design 10/10, the movement and actions everything was accurate, but if it's excellent why did i gave 9/10? because some times they made a few mistakes XD  

i don't know where to start, OST was lovely, and it feels good + totally synced with the atmosphere of the story and events, character voice actors are the Best part they did a pretty good job and there are other creatures sounds they did a magnificent job on it too

characters designs are perfect, their style is unique and lovely, and the eyes were beautiful if you are an animator or design artist you will get what i mean i recommended to watch it in 1080p XD

everything is perfect so far, and they covered the whole story. i compared a few parts with the manga, in my opinion so far so good. i would recommend this one to fans of space and sci-fi stories
