The game have bugs here and there but the lore includes the anime, manga and light novel in one so it's a really good read. The gameplay also have a puzzle element to it despite being an auto turn based game, you need to have the right timing for combos and such.
Overall, 4 star, just because of the current bugs, but since we'll be having a patch update by the end of December, I hope I can edit this to 5.
