It was officially announced in the web PV for its upcoming fourth tankobon volume to be released next Tuesday that an anime adaptation of Gaku Kuze’s comedy manga Uramichi Oniisan is now in the works.
The manga has been serialized in a web manga magazine comic POOL since May 2017 and has printed more than one million copies.
While he looks a very pleasant man, he is mentally unstable and often shows his off-putting adult dark side to children.
