|Japanese name:||島 鉄雄|
Tetsuo Shima is Kaneda's best friend since preschool and the second principal subject of the story's theme. Tetsuo is shown as a black sheep in the gang he and Kaneda are part of, and quietly suffers from a deeply rooted inferiority complex. He admires his friend yet at the same time strongly resents his own reliance upon him.
Spoiler!After his psychokinetic abilities manifest, Tetsuo quickly becomes Kaneda's nemesis; he desires Kaneda's motorcycle (a symbol of status and power) and seeks to prove himself supremely powerful, without need of protection. Eventually, his power overwhelms him.
