Master Keaton, Vol. 5

The series is primarily episodic, with most chapters functioning as self-contained stories that resolve within one or two installments. While there is no grand, continuous narrative, the series does feature recurring character development regarding Keaton's relationships with his father, his daughter, and his ex-wife.

Yes, a 39-episode anime adaptation produced by Studio Madhouse exists, which originally aired between 1998 and 2000. It covers a selection of stories from the manga rather than adapting the entire series.

A sequel titled Master Keaton Remaster was serialized between 2012 and 2014, set twenty years after the events of the original series and collected into a single volume.
