By far the worst book in the series, even toppling the boat ride. I don't think I've ever wanted a fight to end so badly as this one. Fanatix taking up near 80% of the book before finally moving the plot forward.
Tanaka Yuu should honestly quit writing bad fights where he has to write out explosion sounds like a twelve year old writing a school assignment novel, instead of actually describing the scenes and what's happening. Nothing has ever topped Fran's awakening and it feels like every book since has been a roller coaster ride or downward spiral in both writing and content. Which makes me think that's where it was supposed to end and the rest just has been filler because it became too popular for what it was. Now he has to do world building and geopolitical quarrels between countries he haven't made up the names of yet and up the stakes and the power levels somehow to give us some progression. Something arguably beyond his current capacity.
I'm honestly not sure if I even want to purchase any further novels in the series, this one burned me so badly it pretty much killed the series for me, an impressive feat after 12 volumes.
My hopes goes to the anime saving this, since it focuses more on Fran's perspective, plus it actually gives her some agency and doesn't use Teacher as a constant author self insert with inane comments about situations.
