Aliens, a boy becomes a girl, and yuri....somehow good? That's right this show is actually good. First off, it is yuri, so that needs to be taken into consideration. I got into this anime because I was interested in this yuri thing. Turns out I chose the right show. If you are a yuri fan you will really like this! There is just enough physical activity that it doesn't take away from the show actually being good. It doesn't try to be just an in-your-face-yuri-fest. My only complaint is actually the alien aspect. While they doadd to the story, I feel like it takes away from it being taken more seriously. The only thing is I don't know how else the boy could be turned into a girl genetically, so I suppose that is an issue. Either way, this is a fun, but serious and actually interesting yuri! I highly recommend it to fans.
