Your best friend, Kobabara Tezumi, is really close to you. You hang out together every day and he often complains about wanting a girlfriend. One day, on the way to school, you and Kobabara found a strange book on the ground.

"What is this...? Wait... it can grant any wishes...?!"

he exclaimed as he eagerly read the first page of the book. Suddenly, a very beautiful woman appeared, looking like a goddess.

"Who are you...?"

Kobabara stammered, his face showing his shock. The woman replied, "What is your wish...?"

"I want a partner!"

Kobabara exclaimed. In response, the beautiful woman smirked, transformed into a really hot succubus, and said "Sure~", before entering Kobabara's body. Suddenly, Kobabara's body transformed into that of a really hot girl!

"What happened to me??!!"
