Suguha Kirigaya is Kirito's cousin.
Suguha Kirigaya is created by Reki Kawahara who has no information regarding any inspiration used to create her.
Suguha has black eyes and short black hair that has long bangs at the side. For her virtual persona (Leafa), she has long blonde hair tied into a ponytail and green eyes. Her outfit has a green and white scheme, and she has white pants under her green warrior skirt. Her bust is more revealing than her real self.
Suguha is confident when she is doing kendo and when she gets flustered with Kirito, she loses composure.
