Although this may yet be another generic "exiled from the heros party" manga, one thing I note that it does something different is that he's given an ability that uses his original ability. Unlike so many other manga of this same concept.
its not a chick, its a guy.
Ik, kinda weird. but it is what it is
Edit: He's the person that put aphrodisiac in the room while they were all in there, like 1 or 2 chaps ago
Actually I'm just now realizing that she probably wasn't part of his class, but that doesn't excuse him just continuing to indulge someone he barely knew.
That's not really the thing I'm really mad about, it's just its not being loyal to the only friend and person that decided to help you. The girl I'm pretty sure is part of everyone in his class that made fun of him. So, for him to just up and forget how she treated him apart of everyone else...
I am also utterly in awe of a comedy ecchi protagonist that for once gives into his desires and actually does the deed. Completely and utterly astonished.
I don't want to say it, but I have to. This Mc was a total idiot this chapter. I could not stop thinking how dumb the guy was the entire chapter. Actually almost got me to drop this in a single chapter. Almost.
