DYREM

Note: There's no magic in this novel. This was previously in the Realistic Fiction genre but it's not included in the choices. So I picked the closest one to it.Onoda Ruki is just your ordinary high school student. He strived for being the Classmate A who's unimportant to the story.Despite being the Classmate A. Onoda has a secret desire which he always had ever since young and that was to steal each and every girl from their guy.Join him as he entered his high school days as he conquer and steal every girl he sets his eyes on. And along the way, the growth in his character and those around him.

Kuramoto Daisuke, a freshman in High School was suddenly exposed to someone vanishing in front of him. Turns out he was admitted to a Special Class full of Isekai Heroes that were regularly summoned to Otherworlds since the start of their Middle School. He was told that he was to become their Support to prevent each of the Heroes' fate of dying in the world they were summoned into. Though mediocre, he realized that his ability has a great potential but it needs a lot of hard work on his part.Unconvinced of being just the Support Character, he vowed to excavate his mediocre ability, all the while supporting the Heroes using it.And maybe more.
