Black Jack - Season 1 Episode 2 Funeral, the Procession Game

Six months ago while in S-city, Black Jack saves Rei Fujinami, one of four girls who is injured while ice skating. Now, during a stop-over in S-city, he encounters the same girl who asks him to treat Yumiko Inoue (Rei's friend) who is in a coma after an 80m fall. Of her other friends, Yuki was killed by a speeding car and Kaori committed suicide 10 days later. Jack examines Yumiko in the wealthy private hospital inherited by Tokio Umetani, although Umetani is more interested in car racing. Jack operates on Yumiko to remove the hematoma on her brain, assisted by the hospital surgical team. Jack discovers that the girls became addicted to mescaline from a small, spiny cactus after finding them growing on Mt. Senin and informs his friend, Police Lt. Takasugi. He accuses Umetani of cultivating the plants and attempting to kill the girls to hide his secret, however they are suddenly interrupted by syndicate operatives who abduct them. They are left on Mt. Senin with the plants ablaze and a ticking time bomb, however Jack just manages to drag himself and Umetani free before the explosion. Later, he bids a fond farewell to Rei and Takasugi.
