Hasegawa Taizo a.k.a MADAO
MADAO means (ma)ru de (da)me na (o)ssan: good-for-nothing old man
He's an unlucky character from the manga/anime Gintama. Time ago he worked by the government, but Gintoki crossed in his life and...now he hasn't a job T.T. His wife leaf him, he hasn't a home, he's under a unlucky star.
According to Kitaooji Daigorou school report, Madao is the master of the park. A creature with a beard and sunglasses. It sits in the park all day without work. But his teacher corrected him saying Madao is an unemployed middle-aged man living the park.
Btw, i love him, because he's so miserable and unfortunate that you MUST feel love and sympathy for him.
ALL WE HAVE A MADAO INSIDE US
