Gaia, a gravity mage in an S-rank party, is kicked out by his clueless leader, who thinks his magic is only good for making luggage light. In reality, Gaia was secretly carrying the entire party: increasing enemy gravity to pin them down while adding tons of mass to his allies' weapons at the precise moment of impact to multiply their attack power tenfold, making him the ultimate support caster. After being exiled, Gaia meets a group of rookie female adventurers who form a party with him. They are utterly stunned by his game-breaking gravity support, falling completely for his skills and character. Supported by allies who actually appreciate him, Gaia unleashes the true, world-altering potential of his gravity magic!
