- Description from novelbuddy

Severin Reignhart was just an ordinary gamer—until a truck accident sent him into the world of Legacy of Heroes, a novel he had once read.But instead of becoming the protagonist or even a powerful villain, he finds himself reborn as a complete nobody. An extra with no screen time, no future, and worst of all… no real strength.His so-called Talent Ability—Command—doesn’t make him stronger. Instead, it grants a 300% boost to the abilities of those who are bound to him and follow his orders. A powerful buff, but utterly useless when he is weaker than even the lowest-ranked students at Zenith Hero Academy.Thrown into a world where strength is the only law, Severin quickly learns that if he can’t fight, he’ll be crushed. Refusing to accept the fate of an extra, he turns to manipulation, deception, and blackmail, using his intelligence to twist the battlefield in his favor. If he can’t be the strongest, he’ll control the strongest.With the looming threat of world-ending catastrophes and prodigious heroes destined to take center stage, Severin must navigate the deadly hierarchy of the academy. He will recruit, betray, and outwit both heroes and villains—because in a world where power is everything, strategy is his only weapon.And one thing is certain: he refuses to die a nameless extra.
