Story: 1/10
What story? It's just your typical schoolgirl series with motorcycles about their daily lives.
Art: 3/10
The art was horrendous. Stilted animation, horrible character design, and whenever they were riding their motorcycles, they suddenly became 3D along with the entire background.
Sound: 3/10
The music was terrible. The only song I kind of liked was the ending. Otherwise, the music they used in the scenes was so simple and forgettable.
Character: 2/10
All of them are 1-dimensional and get no character development. The only reason I'm not giving the characters a 2 is because I will admit, all of the girls are really hot.
Enjoyment: 2/10
I don't know anything about motorcycles, but even if you do, I guarantee you that you will not enjoy this series. It's boring and random. The only source of enjoyment is the fanservice.
Final score: 1/10
Don't watch it. Just don't. There are way better schoolgirl anime out there than this poor excuse.
