Shuji Hanma and Kisaki Tetta are colleagues who work and join some members of Bonten led by Mikey. The two of them lived in the same mansion, one night when Kisaki was relaxing in the room with Hanma who had not come home.

Suddenly a light shone on the room making Kisaki dazzled, surprisingly Kisaki turned into a beautiful young girl.

And they were seen by Hanma who had just come home to see his colleague turning into a woman.
