He came to Konoha with his siblings Temari and Kankuro, and with his mentor Baki, to participate in Chuunin exams. From the first look, he was shown as merciless and violent individual. Due to his hard childhood, and lack of love, Gaara grew up hating everybody around him, loving only himself. In fateful incident about 6 years before the main story time, he made himself a tattoo of Japanese Kanji letter "Ai," which stands for "Love."

Howl is a mysterious, reclusive wizard who is known for being very flamboyant and wicked. His notorious moving castle has recently been spotted near Market Chipping and rumors have begun to spread that he is searching for beautiful young women whose hearts he may steal. He comes from Wales, a country unknown to most in the book, where his family still remain unaware of his activities in Sophie's world or of its existence. Despite his reputation, Howl is in reality an endearing, charming man who is intelligent and considerate, if somewhat self-appreciative and stubborn at times. He enjoys "slithering out" of uncomfortable situations, often in comical ways. Howl is described as being tall and suave, fond of dyeing his hair and wearing impressive suits. However, he is described by Calcifer as "very vain for a plain man with mud-colored hair."
