Giant Ojou-sama

Fujido Oriko, the young and well-endowed leader of the Fujido Zaibatsu, controls Japan's vending machine industry. Her personal butler, the peculiar Dr. Sebastion, is always by her side. Their lives take a dramatic turn when a monstrous creature attacks the city. In a moment of crisis, Dr. Sebastion provides Oriko with an experimental energy drink developed by his R&D team. The drink's unexpected effect causes Oriko to rapidly grow, matching the kaiju's immense size. Now a giantess, Oriko must confront the rampaging monster. The anime explores her struggle to protect the city while attempting to retain her dignity amidst the chaos and her newfound size.
