I'm actually enjoying the transition from quasi-very-lesbian SoL to wizards and dragons fighting eachother. Kobayashi is badass, she's not even showing a hint of fear during the battle.
Well that's what the author do with alot of his works, abrupt genre transition. Personally I like them all the same.
Also...
Kobayashi's Genkidama! Lucoa's sharingan! What a badass chapter, I'm loving it.
I think Cool introduced enough ancillary elements earlier in the manga to make this genre transition less bumpy/abrupt than it could have been otherwise.
