A Teacher and a Pupil

Synopsis

Hisao tries to fake illness to skip school, but his mother sees through it. His real reason: he can't do math and fears being scolded by his teacher Muramasa. Hisao daydreams that if he had a disease or injury, he wouldn't have to go to school. While lost in thought on his way to school, he's hit by a motorcycle. He's in critical condition with both legs possibly requiring amputation. Muramasa learns that Black Jack might be able to save them and desperately calls for his help.
