I'm gonna start this review with the pros of this anime. The storyline, I thought, was very interesting. The concept of two girls coming from space and taking human form is what made me want to watch this. The characters are okay. Some of the characters are just unneeded and unwanted in my opinion. I thought that ending was good though.
Okay, now the cons. The anime started out strong like I already said. The problem with starting off strong is you have to stay strong. This anime, unfortunately, didn't. Episodes 2-8 honestly, I don't even want to call them filler episodes because some of the episodes didn't even tell you anything. Some of the episodes were just really unneeded. I watched the dubbed version. If you watch, be prepared for Hakari's voice because her voice made me want to just watch the subbed version. I found that this anime turned more into a romantic drama because of all the love triangles that happen. There's a love triangle between Takeru, Hakari, and Mari even though Takeru and Mari are cousins. There's also a (family) love triangle between Ryou, Kimi, and Akari. I feel like you could've probably watched the first episode and then the last 3 episodes and you would've understood what happened. If this anime was over 12 episodes, I probably wouldn't have finished it. There's also a lot of unnecessary nudity.
Overall, I wouldn't recommend this anime to someone. Even if I did recommend this to someone, I would say to just watch the first episode and then the last 3 because those are really the only episodes you need to watch.
