I love it.
The story is fun and engaging and manages multiple arcs in just 21 chapters! It stays lighthearted even when the government attacks them or they're sucked into another world.
I'd even go so far to call it Rick and Morty but with an artstyle that doesn't make you puke. 9/10
The characters are nice though not the best part. Other than Mikadodai everyone falls perfectly under highschool tropes of every other manga (Ikeda could've just been a super strong delinquent; doesn't change much if she's an alien). They all do contribute to the story nicely though so I don't have bad comments. A strong 7/10.
The art is the highlight for me. It's so adorable!!! It felt similar to Boku no Kokoro no Yabai Yatsu or the aforementioned chibis from Komi-san. I love both of those mangas so I had no problem with immersing myself in this one. I also liked how expressive everyone was. Usually there's a stark difference between a character's usual look and a reaction but here no one changes physically to make it funnier or goofier, it's just a reaction.
Best part of the manga, 10/10.
All in all I highly recommend this manga if you're in for a cute story about a literal galaxy brain girl solving galactic politics while enjoying high school. Can't summarize it better. Just go read it.
