Seems I have a weak spot for grand action romance centered around high schoolers, because I enjoyed this very much, probably more than this manga deserves. The story was convoluted in multiple points, giving a foggy feeling as I read the story. There were too many plot twists for the story in the last 10 chapters. But, the romance was a treat, even if a side to the main action. And boy did I like the action, large fight scenes I can immerse myself in to contrast with my bland life. The science fiction elements were silly, but science fiction, focusing much more on fiction than science, is inherently silly. The story gradually moved away from school life to more grand scenes, but I'm fine with that as the MC developed throughout the story. I'll need to reread this later, at a slow pace this time to fully take in what the story has to offer. Also, the story's grand nature reminded me of Sora no Otoshimono, although this manga felt much more mature than Sora.
9/10.
