These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Alas, Poor Villain — Attempted with Surma, Minamoto's predecessor as she breaks down and her Freudian Excuse is revealed. It doesn't work too well.
Angst? What Angst? — ....aaaannnnnddd on the three espers under his care practically never lose sleep about the legal and social discrimination they face, and frequently tease Minamoto for being a worry wart.
Brain Bleach — When the vacationing BABEL-ers see a giant monster that turns out to be a giant naked Tanizaki being projected by "The Little Mice" team
Draco in Leather Pants — In story example. No matter what Kyosuke does (see Moral Event Horizon below) Kaoru sees him as more tragic than villainous. Minamoto is considerably worried by this.
Of course, Kyosuke cheats. Image management is a lot easier when you can erase memories.
She eventually decides that he's too much of a villian for her to tolerate when he colony drops a satellite to distract them while he goes to rescue his followers.
PANDRA and Hyobu leap over the horizon in chapter 161, when Hyobu brings down a satellite to crash on the city to distract BABEL. And in 163 Hyobu finally tries to kill Fujiko for real — only to be interrupted by Kaoru.
Values Dissonance — Minamoto slapping Kaoru after she (verbally) lashes out at her family. Kaoru then retaliates in her usual style.
Villain Decay: Averted. It's clear that Kyosuke could wipe out countries (And does in fact take one over) if he had a care to, he just has in-character reasons not to.
