Tensai Majo no Maryoku Kare

Nayu, a one-in-10,000 magic prodigy, has run out of mana! Now all the antics she got away with because of her magical skill are coming back to hit her like a boomerang… Until she runs into her old student Komugi, the only one who treats Nayu like a normal person. This is a boomerang love-comedy of karmic retribution about a witch who has become painfully useless after exhausting her magical powers.
