Mutsuzou (六二三) is a character in Sengoku Ran in the Warrior Kero series. Unlike most of the characters, he dosen't live on Sengoku. He looks just like Mutsumi but with a timid personality. He loves to draw manga art (which he is not good at), but later Kururu influenced him to try poems, and he agrees. He is also one of the guardians who saved the planet and remembered just as he was about to leave the planet and when his weapon came to him.
Mutsuzou's name, 六二三, is composed of the Chinese characters for six, two and three, respectively.
