"No matter how far you go, you’re just a chore boy after all!" Fool, an F-ranked adventurer who can only use the single-target recovery spell "Heal," was despised as the guild's errand boy and spent his days in misery. He dreamed of one day being taken on quests as a full-fledged Healer, but was suddenly told he was being exiled by Daren, the Guild Master and leader of an S-ranked party. Fool was at his wit's end, but his encounter with a beastkin girl named Cecilia changed his fate significantly――!? By making full use of his infinite mana, Fool rises to the top alongside reliable companions, aiming to become a first-class Healer!
