Summary

Official Details
After suffering a severe blow to the head, Seigo Hasegawa awakens to find his life completely upended. What initially seems like a standard injury quickly reveals a bizarre and overwhelming side effect: his libido has inexplicably surged by four thousand times its normal capacity. This sudden transformation grants him an extraordinary level of sexual prowess, turning his everyday existence into an unmanageable struggle as he attempts to navigate the world with desires that far exceed human limits. Caught in the middle of this chaotic new reality is Anzu Yagami, Seigo’s devoted childhood friend. Because she feels directly responsible for the accident that caused his head injury, Anzu is burdened with a deep sense of guilt over his drastic condition. Determined to make amends and support him through the intense physical changes he is enduring, she resolves to take matters into her own hands. Driven by a mix of personal obligation and lingering affection, Anzu makes the bold decision to assist Seigo intimately, offering herself as the solution to his overwhelming dilemma.
