Kintaro Oe is a 25-year-old freeter, pervert, and "travelling student". Despite having met the requirements for a degree, left Tokyo University without graduating. Golden Boy depicts him living the life of a free spirit, roaming Japan from town to town, job to job. During his travels, Kintaro meets several women whose lives he dramatically changes, despite poor first impressions. He constantly observes and studies the people and events around him, recording his findings in a notebook he carries on his belt.
