Kashita Maryoku wa [Revo Barai] de Kyousei Choushuu

In RPG-style worlds of swords and magic, magic points are the resource that powers spells, techniques, and standout abilities, and running dry leaves a fighter stuck. Lent belongs to the rising party called the Skypiercers, and his unique Gift lets him lend out enormous quantities of magic, keeping his allies supplied no matter what. Once those companions grow into powerful heroes thanks to his help, however, they begin doubting whether they still need him and force him out. Enraged, Lent then uncovers a hidden facet of his Gift, and together with his mischievous fairy companion he sets about reclaiming every bit of magic he lent his former teammates, plus interest.
