Gin is fairly ordinary in terms of clothing, and he doesn't wear any unique items. His overall appearance, however, is not as normal. He keeps his eyes constantly narrowed to slits, rarely ever opening his eyes enough to visibly reveal their bright sky blue-color.[2] Although he appears to be an early to mid twenty-year-old person, he is unusually thin and tall with very sharp features giving him a skeletal appearance. He bears unusual silver hair (his name refers to his hair color; gin [銀] is Japanese for silver).[2] He also keeps his face set in a wide mocking smile, which he only wipes off on rare occasions of annoyance, surprise, confusion, or even sadness.
In Hueco Mundo, his outfit, like Aizen and Tōsen's, has been modified since the three abandoned the Soul Society. He now wears a long, white robe over his normal Shinigami hakama. The hilt of his Zanpakutō is visible sticking out from under the robe through the opening down to his waist. Later Gin is seen wearing a white hakama like the Arrancar, instead of the black ones he was last seen in. Gin wears his robe open in a narrow 'V' down to his waist, closed to below the hips, and then open again to the hem, which falls about mid-calf. His robe has long bell sleeves, into which he hides his hands like some do with kimono sleeves. The lining of the robe and edges or layers of the under-robe(s) appear to be black. From other examples, it is likely he is also wearing black tabi with white waraji. HisZanpakutō is not visible with this outfit.
Personality :
Gin is one of the most mysterious Shinigami in the series, since his almost constant smile and slitted eyes, combined with his heavy use of sarcasm and mocking politeness, make it very difficult to discern his thoughts. Many find his demeanor and appearance rather unsettling and there are very few who were willing to trust him even before he was revealed as a traitor. Gin seems to be fully aware of the effect he has on others and more than once has been seen toying with people's emotional states for his own amusement. Both Rukia Kuchiki and Wonderweiss Margela have shown to be rather frightened of him; Rukia noted to herself that she felt like she was being strangled by snakes whenever he spoke, even if he was not speaking to her directly. Gin speaks with a distinct Kyoto dialect, which is polite but indirect.
Ever since he was a child, dried persimmons had been his favorite food. Planting and raising many persimmon trees around the Third Division offices, Gin would make the dried persimmons himself before distributing them to other divisions. Due to mistaking a dried sweet potato for a dried persimmon he developed a dislike for the former. During his free time, while still a captain, Gin would often go out for walks around Seireitei. Despite his hobby supposedly being people-watching, it would seem as though he also enjoyed hunting around and searching for an opportunity to create mischief with some poor victim.[3]
History :
While living in Rukongai as a child, Gin found Rangiku Matsumoto, a child herself, collapsed on the ground. He offered her some dried persimmon, which he was carrying at the time, telling her that if she could collapse due to hunger, she must have spiritual energy. Rangiku recognized that he must have spiritual energy as well. Following, Gin introduced himself to Rangiku, Rangiku commented on the strangeness of his first name.[4] Gin and Rangiku's shared love of dried persimmon can be traced to that day.[5] Following their meeting, Gin and Rangiku started to live together and it was during their time together that Gin asked Rangiku when her birthday was and she replied she didn't know, as she never really counted the days until she met him. Gin then told her that from then on, the day they met would be her birthday.
Gin also encountered Aizen while he and Rangiku still lived in Rukongai. While gathering firewood in a forest, when he spotted Aizen and three other Shinigami (who were kneeling on the ground before him), through a clearing in the brush. Spying on them, he saw Aizen take a ball of pink energy from one of the Shinigami's hands and put it in a glass that contained the Hōgyoku.[7] It was then revealed that earlier, Gin had seen those three Shinigami leaving the area where Rangiku was collapsed, carrying said ball of pink energy that he saw earlier.[8] Realizing that Aizen must be the leader, Gin resolved to kill him.[9]
Gin had a habit of leaving Rangiku most of the time and not telling her where he was going.[10] During one such incident, Rangiku found Gin draped in a Shinigami's Shihakushō with blood on his face. When Rangiku asked him what he was up to, he replied that he had decided to become a Shinigami and change things so they would end without Rangiku having to cry.[11] Gin and Rangiku joined the Shin'ō Academy together.[5] Since then, Rangiku has been one of the few people Gin seems to truly care for
Approximately 110 years ago Gin graduated from the Academy after just one year, and was given a seated position in the 5th Division. One night, Aizen found Gin after the latter had killed the then 3rd Seat of the 5th Division. Aizen praised Gin's efforts and asked his opinion of the 3rd Seat, to which Gin replied that the 3rd Seat was worthless. Aizen immediately gave Gin the now vacant 3rd seat of the 5th Division and covered-up the fact that Gin had killed the 3rd Seat
