Manabe was born in Chigasaki, Kanagawa, where he was inspired to become a mangaka by reading Doraemon in primary school.[1]
His one-shot Smuggler (2000) was about an illegal transporter of dead bodies getting in trouble with the yakuza and the triad killers. It was adapted into a live action film in 2011.[2]
Manabe launched Ushijima the Loan Shark in Weekly Big Comic Spirits in 2004 and ended it in March 2019, after 46 volumes. The manga depicts the life and activities of a yamikin, a Japanese loan shark, in a detailed and realistic way. During the 2010s, it was adapted into a live-action TV series, which ran for three seasons, and four live-action films.[4]
His Kujō no Taizai series has been serialized since October 2020.[5]
