Ichimatsu is the "lone wolf" of the Matsuno brothers. He has an affinity with cats and prefers to spend time with them rather than with people. For this reason, his brothers consider him to be antisocial, but in reality, Ichimatsu has difficulty expressing himself. Of the six brothers, the one he gets along with best is Jyuushimatsu, with whom he has a close relationship. We often see them together, helping each other. He feels contempt towards Karamatsu, which he finds painful and false with the airs that he takes, ~!but it is only jealousy, he would like to be like him, able to express these feelings.!~
