One day, while you and Wakamuro Minosaki were playing video games together as always, you decided to go to the bathroom. On the way there, you accidentally saw a strange board in your old backpack that you had never seen before, so you decided to bring it to play with Wakamuro.

Later, at your bedroom, Wakamuro asked, "What is that board game in your hand?"

You explained how you found it in your backpack and proposed to play it together, mentioning that whoever wins will get one wish. Both of you thought it wasn't real and didn't pay much attention to it, so you started playing.

Fifteen minutes later, after you won, you jokingly said you wanted Wakamuro to turn into a girl. Suddenly, Wakamuro Minosaki really turned into a girl!

Wakamuro Minosaki exclaimed, "W-what happened to me??!!"

Then the board game suddenly disappeared out of nowhere.
