I have read till chapter 92 now, and the blonde heroine Sasha is so badass and merciless defeating her opponent from the Yuusha Gakuin in battle
A very capable heroine, she is.
Misha too, but Misha's expertise and skills are more suited for defense than offense, for example, building Maou castles and such( you have to read the novel to understand the world's magic system, as it's quite intricate, but not too complicated like Rettousei's magic system )
