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...
Two years ago, I realized the truth, 
and decided to become stronger.
Hace dos años,
Hace dos años, me enteré de la verdad,
y decidí hacerme más fuerte.
Há dois anos, eu percebi
 a verdade e fiquei mais forte.
