2 years ago, the genius surgeon "Dr. Chocolate" suddenly appeared in Singapore. No matter the patient or the surgery, he always succeeds. However, he has 3 conditions, 100 million yen in cash, a non-disclosure agreement and chocolate. No one will talk about his identity, but he is rumored to have a prosthetic hand. On a flight from Singapore to Japan, a captain suddenly loses consciousness, and Noda Tetsuya and Terashima Yui jump into action. Okuzumi Nagisa, a reporter, notices Noda's prosthetic hand as he passes her. However, it's not Noda that tends to the patient but Yui, the 10-year-old Dr. Chocolate.
