Lent Mana Is Collected by Force via Revolving Credit

This is a world where the "Gifts" bestowed by the Creator God drastically shape one's life. Rent, a kind-hearted boy living in a frontier village, receives an extremely rare support ability called "Mana Vault," which allows him to "lend" his mana to his companions. He forms a party called "Sword of Severing Space" with his childhood friends from the village and embarks on an adventure, driven by his mission as a supporter. However, Rent, who remains perpetually weak, is viewed as a burden and is mercilessly "expelled" from the party! As intense anger and a desire for revenge ignite within Rent, his Gift evolves, awakening his true power. It is a skill that allows him to [forcibly collect] the massive amount of mana he has lent out over the years. The story of Rent's "revenge," as he reclaims his mana from his former comrades who betrayed him and grows stronger using it as fuel, now begins!
