Tenma is the third son of a director of a prestigious hospital and a former editor of a medical publisher. Both of his parents had previous divorces, and his father had two sons from his previous marriage, who are seven and two years older than Tenma. Tenma stood out for being a bright boy who's always the top of his class; this allowed him to attend the best schools in the city which made his father proud. Throughout his life in Japan he made very few friends and didn't forge strong bonds even with his own family, which is one of the reasons given by Dr. Takahashi to explain why Tenma came to Germany and never went back. During his teenage years, Tenma loved music. He learned how to play guitar but didn't join a band, maybe because he didn't want to be in a group. His talent for music eventually became dormant as he got very busy with his studies. He also participated in the school's track and field club. He entered one of the best schools in Kanagawa prefecture. His path was pretty much set in stone by his father at this time: he would inherit the Hospital and become its new director. Despite being his younger son, his father found his brilliant scores far superior to his older brothers'. This upset Tenma in some way, thus, he refused to accept his father's request. His eldest brother opted for a career in Economy, so appointing him as a hospital director was out of question. His second-eldest brother, however, was following in his father's footsteps, but it took him two years to enter a medical school and his university was much less prestigious than Tenma's. Still, Tenma wanted his middle brother to be the new director. Tenma's mother agreed with his choice because it benefited her less talented stepson (the novel mentions she favored her stepchildren over her own biological son with no given reason), but Tenma's father didn't change his mind. Tenma was going to be forced to inherit the hospital whether he wanted it or not. What ended up changing the course of Tenma's life was an outstanding thesis by a German medical professor at Dusseldorf University named Udo Heinemann. The thesis, printed in a medical journal, was a paper on the care of Alzheimer's disease victims. Tenma made up his mind on a whim that he would leave Japan and study under Heinemann, forcing his father to give the hospital to his brother. Using his scholarship fund, he went to Düsseldorf University in Germany and spent a year in a language school to clear the requirements to enter into med school. Then, he graduated and now he is specializing himself in neurosurgery, and finally, he found a job at Eisler Memorial Hospital whose director was Dr. Heinemann. But he doesn’t work at the hospital right now because he has a project that he wants to do, which is combining human brain with ai and for that he should work with a computer engineer.
