To defeat the strongest Magical Princess Ai, a demon devises a plan to control her butler and force her to eat the "Demon's Bud," a substance that transforms pain into pleasure. Following the demon's orders, a classmate-controlled man launches an attack. Under repeated assaults, Ai falls under the influence of the "Demon's Bud" and unintentionally urinates. Further ambushed by her own butler, her psychological distress is also converted into pleasure, leaving her unable to fight or even move. Is this the moment Ai begins walking the path of the demon's domination?! [BAD END]
