Summary
In a world overrun by monsters, a young man consistently ranked last at his hero academy. His power not only seemed weak but also debuffed nearby allies, earning him scorn as a burden. After being lost in another dimension, he discovers his true ability is not output but input—absorption. He had been unintentionally siphoning others’ strength. Now awakened, he learns to absorb enemy attacks to nullify them and gather external energy to empower himself, forging a path to become the ultimate hero.
