Ball

Ball (ボール, Bōru) is a strange kid with dreadlocks who loves round things and joins up with Ruby and Jio after the events in Entotsu City, where he lived with his parents and younger sister. At first, Ball loved to pretend to be an OPT and to show off. He was greatly surprised when Kirin revealed to him that he was indeed a true OPT. He then received his O-Part, called Cool Ball (C rank), and its effect is Magnet (Magnetism). Post time-skip, he wields a new O-part, called Tricky (B rank), which are smaller versions of Cool Ball that seem to resemble marbles. Ball is revealed to have a very good sensitive ear, and is able to distinguish different notes just by hearing them, although he can't play any instruments. He sometimes serves a comedic role in the group, as his occasionally perverted ways get him into trouble.
