This time we discover the past of a character who's always been somewhat of an enigma. As she's also an ib, she's also as warped by the world as the rest of them but until the last chapter I didn't realise just how much. It's really interesting how the characters who seem something else at the beginning have a wholly different side to them. The mangaka has done a very good job at keeping the characters realistic and well-rounded instead of giving them a single trait. But then, that's to be expected from the guy who wrote Kaguya Sama, I suppose.
