Black Jack 21 - episode 7 - 28 May, 2006

Black Jack and Pinoco arrive in a middle eastern town after leaving the damaged Sky Hospital. While there, they befriend a Japanese man named Aritani who is there on business. Later that night Black Jack is arrested and accused of murder, but Pinoko finds Aritani who provides an alibi for him. Jack offers to repay the favor with a free treatment if ever required. Later, Aritani returns to his office in Germany where he is pressured to take the fall for his company which was redirecting money illegally to an unknown organization. However, after taking responsibility for the missing funds, Aritani is thrown in front of a train and ends up in a critical condition. Desperate to save Aritani's life, Jack races to Germany but is unable to operate on Aritani without a licence. After he inspires the owner of the hospital with his determination, Jack temporarily buys the hospital and saves Aritani. After he recovers, Aritani says the redirected money was used to fund the Noir Project. (Source: Wikipedia)
