Hikari Yagami is one of the main characters from the original Digimon anime and manga.
Taichi's younger sister, and the Eighth Child, not that anyone knows it at first. Very kind and innocent, but also often wise beyond her years. She has the Crest of Light, which is only fitting.
In Digimon Adventure 02, even though she has grown up, Hikari remains sweet and gentle, having tempered her innocence with wisdom. However, she still has issues that come back to haunt her, usually when she least expects it.
In the XP4 fics, Hikari debuted in XP4 Heroes Coalition - Kick-Off!.
In the AWA fics, Hikari is a student at the AWA Academy.
Hikari has a short brown hair and has brown eyes. She wears a sleeveless white and pink turtlenecked shirt, pink fingerless opera gloves with an oval cut from the top of the palms, yellow shorts with a brown belt, white stockings, and pink and gray boots with black soles.
Kari is kind and sweet by nature, always looking for the best in people, and avoids fighting them whenever possible. Still, she can be serious, especially in drastic situations. As she grows older, Kari is more outgoing and has a playful and whimsical personality, but remains a sensible and grounded person. She tends to consider her own safety as secondary to the safety of others, and thus has tendency to hold any forms of worry or trouble to herself, not wanting to trouble anyone, showing her self-sacrificing nature. Her relationship with Yolei allows Kari to be more expressive, true to her heart, and overcomes the power of Darkness as her friends are always there for her. As a young child, she is prone to illness, but grows out of it.
Kari is shown to have a unique connection to light and darkness, which seems to be related to her associated trait of Light. She is empowered by the powers of light on one hand, but very susceptible to the powers of darkness on the other, leading her to be empowered by light and weakened by overwhelming darkness. Her stronger willpower after forming friendship with Yolei allows her to overcome this negative aspect.
Kari's older brother, Taichi "Tai" Kamiya, is the leader of the DigiDestined. Kari is very close to Tai and hero-worships him for his kindness and strength well into adolescence. Tai and Kari used to share a room, but sometime between Digimon Adventure and Digimon Adventure 02, Tai has moved to another room.
Hikari is a member of the Heroes Coalitions and is part of the Multiverse's Cutest Team as it's second-in-command. She also attends the Vanguard Academy as a student.
