Taida na Akujoku Kizoku ni Tensei shita Ore, Scenario wo Bukkowashitara Kikakugai no Maryoku de Saikyou ni Natta

I don't know how it happened, but somehow I've died and reincarnated into my favorite academy game. And if that wasn't weird enough, I'm now the depraved and lazy villain, Weiss Fansent, whose misdeeds lead him to a deadly end. Something I'm determined to avoid at all costs. With little time left until the academy's entrance exams, I have no choice but to dive headfirst into serious and grueling training. Which means swordsmanship with the S-rank adventurer Miruku Abitas, followed by intense magic practice. It was demanding and exhausting, but getting stronger means I have a better chance of avoiding my disastrous end. But I seriously underestimated just how powerful Weiss truly is, and I wind up stunning everyone at the exams! Have I somehow become more powerful than the hero? A fantasy series about changing the villain's fate with hard work and amazing powers! (Source: Seven Seas Entertainment)
