It's the Kaimei School Festival, and Bossun's class is doing a maid cafe. Everybody's parents show up, and Bossun is approached by a man who claims to be the doctor who delivered him. He has finally decided to tell Bossun the truth of what happened that day, which he has kept secret for 17 years...
I might not have any blood relatives, 
but I got me a great family!
¡Aunque no tengo familia de

¡Puedo no tener ningún familiar de sangre, 
pero tengo una maravillosa familia!
Posso não ter parentes de sangue,
 mas tenho uma família incrível!
