I’m the Slit-Eyed Character at the Academy, but I’m not the Mastermind

For eighteen years, the MC has relentlessly pursued victory in an infamously difficult game, blocked by one insurmountable final boss. His peak performance barely reaches 30% of its health pool. Having exhausted every competent character, he makes a desperate gamble on the Slit-Eyed character—a notorious weakling with abysmal stats and worthless traits. Naming this last resort "Zero," he initiates the game one final time. But instead of another brutal defeat, he regains consciousness inside the game world itself, inhabiting the body of the most despised character imaginable. Trapped within an academy setting, Zero must unlock hidden secrets beneath his pitiable existence—or uncover a truth far darker than anyone anticipated.
