When lazy, erotic-game loving Mahiro Oyama is transformed into a girl by his younger scientist sister's experiments, he becomes determined to change back, only to recognize that with his new opportunity, he may want to turn his life around.

Wisteria is an orphan girl living in a corner of the British Empire at the end of the 19th century. Her life is desolate and bleak–until she encounters Malbus, a powerful but equally lonely immortal being with a furry appearance, hounded by hunters. Together, Wisteria and Malbus roam the Empire–populated by humans and human-like beasts–in search of a place where they can live together in peace.
