A short summary: A hard worker is reborn as a brainy person and aims to become a delinquent magician. A detailed summary: I have finally achieved reincarnation in the world of swords and magic that I have always dreamed of, but it turns out to be a rather awkward world where words like 'academic credentials' exist. ...Well, it's fine, at least I'm in a world with magic. While those aiming for the elite path continue to work hard, I decide to live a free and romantic life as a magician— Wait, I don't have any talent for magic? But I have talent for body-strengthening magic (brainy)? No way, no way, no way! I want to be a sage! I decide to live freely without being bound by academic credentials or promotions, and I start looking for a way to become a magician at a prestigious academy in the capital. However, my somewhat talented body-strengthening magic leads to misunderstandings, and before I know it, I find myself in a big mess... But I won't waver! I will live this life doing only what I want to do! This story is also published on Kakuyomu. [Book] 2024/10/10 Volumes 1-4 are currently available from Kadokawa BOOKS!
