Intro
Kazuma is always having delusions like this:
Girl A: "Look! Kazuma-kun! Open wide, say ahh!"
Girl B: "Hey! I'm the one who gets to feed Kazuma-kun!"
Girl C: "I'm the one who understands Kazuma-kun best... so look only at me, okay?"
He dreamed of a harem, fantasizing about stealing girls from other guys.
And so, on his first day as a transfer student, his incredibly reckless plan to steal them begins.
Standing at the front of the classroom, he writes his name on the blackboard. "I'm Kazuma Kiba! Nice to meet you all!" (I wonder if there are any good targets here...?)
Ignoring the fact that it's homeroom, the three girls were spending their daily life as usual.
