Zu-chan

Zu-chan (ズゥちゃん, Zuu-chan), or just Zu, is another avian mascot for the Chiba Lotte Marines, the youngest of the 3 mascots. He is Mar-kun's younger brother as well. He's pretty sure that he knows a little more about baseball than you do, pal, cause his brother invented it (or so he says)! Not known to anyone, he secretly has a crush on Buffalo Bell.

Appearance
Zu-chan is a seagull and he is very similar to his brother, except he is shorter, wears his cap backwards, and wears a gray Marines hoodie. Just like Rine-chan, occasionally, he would wear a baseball jersey.
