Rettou Hito no Maken Tsukai Sukiruboudo o Kushi Shite Saikyou ni Itaru

Tohru Minasuki, a normal office worker, is reborn in another world after falling through a dimensional rift. A god grants him an ability called Skill Board upon his reincarnation. Taking advantage of this, he acquires essential skills—and an overpowered skill called Magic Blade. Despite his status as a stray—those known as inferiors for being seemingly incapable of leveling up—he pressed forward on the path to becoming the strongest! (Source: K-Manga)
