Fantasy Campus: Game no Kamaseinu Yaku ni Tenseishita kedo, Kimama ni Gakuen Seikatsu wo Tanoshimu

When I turned 12, I, Mizukoto Harutaka, realized that I had been reincarnated into a game as the disliked noble character. No way am I going to let myself be one-hit KOed by the protagonist in the future! Somehow managing to avoid meeting the protagonist, I try to make up for the misdeeds done by this “Harutaka” all this time—while doing so, I discovered that I possessed the hidden spec, “Black-flame user” while studying at the leader of magic education, Touwa Academy. It was a skill that only the boss character was supposed to have. Could it be—I’m actually the strongest!? With this secret ability and intimate knowledge of the game, avoiding the bad flags should be a piece of cake! Source: Overlap
