Manga/Anime Differences Edit
- In the anime, she has glaucoma and Dr. Black Jack performs the operation. In the manga, however, it was a different patient.
- In the anime, the person she continues to see through her new cornea turns out to be the fiancee of the deceased woman whose cornea was donated to Kumiko. However, in the manga, the person the patient sees turns out to be a murderer/assaulter who Black Jack stops. In both the anime and manga, the women had their hearts broken as they had fallen in love with the man they saw and Black Jack consoled them, stating spring would arise for them.
- In the manga, her name was Kumi Yamashita and she was the 18 year old fiancee of Shoichi Maruguri who dumped her after she developed Cushing's syndrome. When Black Jack cured her, he tried to take her back but Black Jack defended her from him.
