Dokka Ichatta!?

Kei-chan wakes up one morning and realizes that something is missing. In a world where high school students can swap genders every day on a whim, he finds himself in an unexpected situation. The ability to change from male to female and back again at will seems like a dream come true, but it quickly becomes a source of confusion and desire.

As Kei-chan explores this new power, he discovers that the transformations come with their own set of challenges. His relationships with classmates and friends become complicated as he navigates the blurred lines between identities. The daily shifts lead to intimate encounters and awkward moments, forcing him to confront his own feelings and the reactions of those around him.

With each change, Kei-chan learns more about himself and the people in his life. But the freedom to swap genders also brings hidden dangers and temptations that he never anticipated. As he delves deeper into this strange ability, he must decide how far he is willing to go and what he is willing to lose.
