Life
Ochiai began his life as the youngest of three sons to Shigeru and Asuka Ochiai. He has two older brothers, being Hotaru and Masaru. At the age of six, he was introduced to a device that would eventually change his life forever: a computer.

During his adolescence, he extensively used computers and played arcade games. He attended King Kishou Elementary and Junior High School, where he made many friends who loved computers and arcade games and met his first girlfriend in 6th grade, Kagami. He and Kagami eventually attended Minecraftia High School after graduating, but broke up after Kagami flunked out at the end of her freshman year. Shortly thereafter, Masaru, his elder brother, left home for college and was left alone with his parents.

Unfortunately, due to his breakup with Kagami, he developed depression. Right after he graduated from high school, his brother gave him the opportunity to attend Minecraftia University. He learned to code and became a game designer. To relieve his depression, he played games on a Nintendo Famicom and made many friends who played the console and met his second girlfriend Kisumi Torisawa.

In 1987, Ochiai graduated with a degree in computer science, and a few months after his graduation, he was engaged to Torisawa. They married the following year and became a father to two daughters: the oldest being Kagami Ochiai (born 1989), named after his first girlfriend, and the youngest being named Yumi Ochiai (born 1992), named after Torisawa's great-grandmother.
