Also known as: 大江錦太郎
The titular Golden Boy from the Sex comedy manga and anime of the same name.
Ooe Kintarou is a 25-year-old freeter "travelling student", who despite having met the requirements for a law degree, left Tokyo University without graduating.
Kintaro is living freely, 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.
