It's getting a bit boring. I really want to see him use PTV to get strong enough to be not be treated as a pet by D. Even if it's a crossover I find the mc's attitude far too happy-go-lucky in a world that is primarily based on Fate-verse (one of the most darkest and dangerous worlds out there) even after so many chapters. Also even if he is a magus his reaction to his whole school exploding is way too bland. So far all he's been doing is act cool, buy and sell some stuff in the store and get bang D(pun intended).
