There's a main story, and it's not that bad. Body switches happen here and there, it's fun and the characters are all likable. What's more, it's original and evolves in unexpected ways, although there's no real ending, and it's a shame.
However, there are also many side stories, and a flashback thrown out of nowhere about the real Akira. We will never get to see her outside the flashback, but it's really good, and the idea of " wimp turning into a super fighter under hypnosis to protect a girl " is really nice, was stylish and would make a great shounen.
The later side stories still remain cute, although I was confused whether the one about Arisu becoming a guy was part of the main story or not, as she's similar to another character, and her loved one is similar to Akane, although it's later shown he's a guy.
I though the last side story would end up following the same scheme of body switch and happy ending, but instead it turns out differently, being quite surprised and offering a good dose of happiness.
Overall, it's pretty hard to understand and I had to sometimes force myself, but it was an enjoyable read and actually made me smile.
