Kirigaya Suguha, known as Leafa in «ALfheim Online» (ALO), as well as «Project Alicization», where she had temporarily used the Terraria account, is the deuteragonist of the Fairy Dance Arc, one of the main characters of the Girls Ops spinoff, and a reoccurring character throughout the Sword Art Online series. Suguha is the cousin and adoptive sister of Kirigaya Kazuto, but was raised along with him as his sister. In order to protect Kazuto from the wrath of their grandfather when he decided to quit kendo, Suguha became an accomplished kendo practitioner in his stead. While Kazuto was trapped in Sword Art Online, she became interested in seeing the virtual world that he loved, thus she began playing a Virtual Reality Massively Multiplayer Online Role-Playing Game (VRMMORPG) called ALfheim Online as a Sylph warrior, after consulting Nagata Shinichi (Recon), the person with the most experience on games in her class. Her obsession with flight in the game has earned her the nickname «Speedaholic» from Recon. Suguha has short black hair and dark grey eyes, almost blackish. Her breasts are very large, compared to other members of the female cast, although she has grown a lot recently. She also has a cute childish look and is often seen with an embarrassed expression, especially when around her cousin. Due to her kendo training, Suguha has strong and defined muscles that show up even when she makes small movements. Kazuto has described her as monstrously muscular and although he claims to be exaggerating, he does state that she is heavier than she looks. In ALfheim Online, Suguha appears more like an adult than a child. She has bright green eyes and wears white and green clothes. She also has a white and green collar on her neck. She has long blond hair, often tied up with a flower-like hairband. Her hair bangs, however, are not tied up with her hair. Like all of the other players in ALO, her ears are quite long and pointy. Suguha's avatar maintains her long blond hair and green eyes from ALfheim Online, and her skin is pure white. She wears a grassy-colored outfit and shiny silver armor. Unlike her cousin Kazuto, Suguha is upbeat and outgoing. She is much more social and converses easily with others. Even when Kazuto began to push her away after finding out they were not really siblings, she still treated him with good spirit and tried to get back in his life. She can be very aggressive towards those that annoy her or cross her and can easily lose her temper. This is demonstrated in one case when Recon attempted to kiss her after confessing his love to her and she punched him. Despite her positive outlook and slightly aggressive behavior, Suguha can be somewhat fragile and delicate due to her young age, especially when her cousin, Kazuto is involved. After seeing Kazuto in a comatose state due to being locked in SAO, she broke down crying for the first time in years. In addition to this, once she found out that Kirito and Kazuto were the same person, she locked herself in her room away from her cousin and went into a slight depression. Most of the time she is quick to rebound from these moments and return to being the same upbeat girl.
