Comments of chapter undefined of SSS-Class: Villain Hero

Weird. I thought he would've killed her for her powers? Especially since Freya is the only one who knows that the MC is in-fact just an ordinary student - and he really shouldn't have been able to defeat a S-class monster. Killing her would've been the wise choice, not only does the world remain blissfully unaware of the MCs oddness but he also gets a new power.
