(From wiki)
He transforms into the Dog of the Chinese zodiac whenever he is hugged by the opposite gender or his body comes under a great deal of stress. Shigure is one of the oldest members of the zodiac. According to the anime, when he turns into a Dog, he's revealed to have black fur.
Shigure is laid-back and anything but solemn and according to the first episode, he says that he's a nonviolent peacemaker. He is a flirt, a tease, and often acts like a pervert. Akito once remarked, "I thought you'd sleep with any woman." He likes to tease Tohru by asking her for dates and often says he likes high school girls. Shigure is a writer of both romance novels and academic books. He loves to drive his editor insane by disappearing whenever she comes to pick up his draft or pretending to not have written anything. His most famous and well-known pen name is Kiritani Noa which he usually uses for his romance novels such as Summer-Colored Sigh. Tohru thinks it's amazing that she knows an author.
Shigure's best friends are Hatori Sohma and Ayame Sohma. The trio, nicknamed the Mabudachi Trio, have been friends since their childhood. While Ayame and Shigure get along very well, it's less certain how Hatori, who is always exasperated with them, became their friend. On the other hand, Shigure appears to have a close friendship with Hatori as it is always Hatori Shigure confides the inner workings of his mind.
It is revealed in the manga that, although he does feel brotherly affection for her, Shigure is actually using Tohru Honda to break the Sohma curse. This is not true in the anime, which deviates from the original manga's plot after a certain point. Shigure is normally seen in a traditional kimono. Occasionally, when he does business, he wears western style clothing (suits).
Occasionally, Shigure shows another side of his character. He can be surprisingly mature and thoughtful, giving rather insightful advice to Tohru, Kyo, Yuki, and other characters. In the manga, and less noticeably in the anime, he is also shown to be dark-humored and manipulative; he claims that he would (and does) use anyone and anything in order to reach his goal.
In the manga, Shigure's relationship with Akito is twisted and complicated. The day Akito was conceived, the already born Sohmas had a dream heralding her arrival and perhaps imparting knowledge of their reincarnations and new roles. While the dream left sad, bittersweet memories for the other Juunichi, Shigure felt only love. This love for Akito stays with him for the rest of his life and is the main driving force of all of his actions. Shigure speculates that, in a way, he is the most affected by the Sohma curse as his obsessive love for Akito is a direct result of the bond between them. There is a constant push and pull between the two throughout the manga. While Shigure tries to break the curse in part to stand on equal ground with Akito and in part to break her ties with the other Juunishi, Akito hangs on by her fingernails to the bond. When, in an act of desperation, Akito slept with Kureno (bird member of Sohma family), Shigure bit back by sleeping with Akito's mother, causing him to be thrown out of the main house.
Although Shigure readily admits his love, he is often very cold towards Akito. He confesses to Hatori that the reason he acts this way is because he "doesn't want to be her father", which implies that Shigure felt that Akito was projecting her late father on to him, as Shigure was initially very gentle and kind with her (Yuki remembers witnessing Shigure comforting a crying Akito as a child). There is also a moment much later in the series during a conversation with Kureno where Shigure states that he loves Akito to the point he wants to crush her.
Shigure lives on the "outside" of the Sohma house in a large home with Kyo, Yuki, and Tohru. In the house, he normally walks around bare-footed while everyone else wears socks. His reason for doing so is that it's his house.
