Kashita Maryoku wa "Revo Barai" de Kyousei Choushuu

Lent was essential to the rising Skypiercers because his Gift allowed him to lend enormous amounts of magic to his companions. Once they became powerful with that borrowed strength, they decided he was no longer useful and expelled him, conveniently ignoring that much of the power they relied on was never truly theirs.

His anger leads to the hidden function of his Gift: he can collect the magic he lent out, complete with interest that grows over time. With a small and delightfully devious fairy beside him, Lent begins repossessing what his former companions took for granted. Every collection weakens the people who used him and strengthens Lent, turning the dismissal meant to end his career into the beginning of his rise.
