Lee Sung-hwan

Aidan, a newly enlisted recruit of the Cygnus Knights had held onto the same dream ever since the day he first saw the Adversary. Like the one who could change the course of a battle alone, he, too, wanted to become a hero who would one day save the world. Yet the battle to protect Maple World proves far harsher than he ever imagined. With every battle, Aidan found himself no closer to the Adversary he admired. Instead, he was reminded of just how small he truly was. Alone amid the ashes of Limina, Aidan struggles back to his feet with nothing left to lose. "Let oblivion take my name. All that matters... is seeing this war through to my hero".

In a world going to apocalyptic hell, the last hope might be a grandpa with a special broom and vacuum. Maybe.
