Sachio (サチオ) was the information gatherer and chief mechanic of Team Nowhere. He first appears as a troublesome child who stole mechanical parts with his friends and gave them to a mechanic in exchange for candy and/or small change.
Sachio's father was originally a brilliant engineer who worked for Shirato Group and later died, making Sachio an orphan with a grudge against Shirato. He then grew up in the forbidden district with the other street children (Bonjiri, Santa, Oicho) making a living off selling stolen goods and buying red "candy".
Season 2: Nomad
After the events of Season 1, Sachio lives at Gym Nowhere with Joe and Nanbu. When the tsunami hits the river, Sachio moves to an orphanage run by Yukiko Shirato. 5 years later, he becomes a Megaloboxer in Fujimaki's underground ring.
- Sachio's appearance is heavily based on Kinoko from the original Ashita no Joe manga, but his name and role in the story are derived from Sachi, who also had elements incorporated in Oicho. His appearance in Nomad is reminiscent of Joe Yabuki from the manga as well.
