Kiriko is cheeky and full of life. She has tongue-in-cheek style humor, and is not afraid of teasing others, regardless of how intimidating they might seem. She exudes youthful energy and intelligence; a combination that makes her extremely personable.[2] She loves to kid around with her teammates,[1] and any disrespect or sass sent her way is simply redirected,[9] Like the Fox Spirit that aids her, Kiriko is a trickster,[10] but while a trickster and light-hearted, Kiriko has a strong moral compass, and believes in taking care of those around her.[1]
Kiriko has a sweet tooth, enjoying doughnuts.[11]
For generations, the Yamagami family served and protected Kanezaka by following traditional paths. Kiriko, however, forged her own path by mixing the old and the new.[12] While she respects tradition, Kiriko believes that traditions must change to reflect modern thinking.[2] The influences of her grandmother and mother have shaped Kiriko into a hybrid of healer and warrior;[13] a bridge of the traditional and the modern. She will do anything to protect her family and community, even if she has to bend a few rules.[10]
Kiriko is cunning and agile. Through her training, Kiriko is proficient in the ways of both Miko and Kunoichi.[1] She is a skilled martial artist, and has demonstrated seemingly supernatural abilities, such as teleportation and healing; in the case of the latter, she utilizes ofuda, but can heal minor injuries without them. She is also proficient in Japanese Sign Language.[11] She is good at basketball, and claims to have never lost a game, and to have never played without stakes.
