The fourth brother. Known as the "joker" of the Matsus, Ichimatsu tend to act antisocial and solemn but rather friendly to Jyushimatsu. He is deeply fond of cats, and loathes Karamatsu just as much (canonically due to jealousy toward Karamatsu's self-confidence and esteem).
The Animate Cafe Ikebukuro No. 3 was newly opened on Jan. 27 and as its first collaboration, the cafe is decked out with all kinds of content themed after the popular anime Osomatsu-san.
