Shigure is the dog of the zodiac and the owner of the house where he, Tohru, Yuki and Kyo live. He is a writer who writes both academic books and romance novels under many pen names. His most common and celebrated is "Karitani Noa" from his erotic "Summer-Colored Sky" novel.

He loves to drink tea, eat takoyaki, drive his editor, whom he affectionately calls "Miichan", to tears by feigning the non-completion of his work, sleep late, and smoke cigarettes.

He's a jokester who occasionally gives advice or purposely stirs up controversy for the good of everyone in the end.
