About"HUSTLE HUSTLE MUSCLE MUSCLE!"
Jyushimatsu is the slightly strange one and the most child-like of the Matsuno brothers. He is generally happy and over-excited almost all the time, and is rarely seen in a serious state. According to Ichimatsu, Jyushimatsu also has trouble blending in with other people due to his extreme child-like personality.
Despite this, Jyushimatsu is seen as the kindest among the sextuplets, as evidenced when he worked the hardest to look for Ichimatsu's lost cat, and has a closer relationship with Ichimatsu than his other brothers.
Unknown to many, he can be serious when need be and show some serious concern for his brothers. Though he isn't one to be left out of things and still participates in the group activities.
