@Cosmak what? we've known about her preternatural ESP powers since like, day 1. She gets put into an exceedingly stressful situation and she uses it uncontrollably, this is a trope that's present in like, all novels where the MC has special powers. Her winning at games due to her unconscious ability use has also been established since she was a baby. Heck, we're basically getting a rundown of Friend's power repertoire through her, from the ESP to the incredible charisma!
@Vainfire don't worry, I did not say that in a bad way Kanna is one of the best characters in this series. But your analysis is great ! I'm sure you could love "Monster" by the same author.
