I Will Return Again α

When Yoshina Tsutomu (♂) wakes up one morning, he found out that he had became a silver-haired vampire (♀) with heterochromia. According to his foster parent Tilura, he was turned from a girl into a boy when he was young because of certain reasons. Now that the effect has ran out, he had returned to his original form.

Outraged at the fact that he became a girl, Tsutomu begs Tilura to change him back, but was told that this will require some preparation time.

And so, Tsutomu changes his name to Tsukasa and enrolls as a transfer student in the high school he previously attended.
