I’m reading the 7th part of this now. This novel is actually amazing. For the most part it adds background information for characters, so it’s better than HF in that sense. Of course it is quite silly at times too. That’s one part of Rewrite I’ve come to appreciate; they manage to sneak in little nuggets of knowledge along with the silly side stuff.
Edit: Done. It got a bit slow towards the end, but the Kagari and Kotarou chapters were phenomenal.
