Kari Kamiya (八神 ヒカリ Yagami Hikari?) is a character in the anime and manga series Digimon Adventure and Digimon Adventure 02. Kari is a DigiDestined, partnered with Gatomon, and embodies the trait of Crest of Light. She is the younger sister of Taichi "Tai" Kamiya.
Kari and Tai's English dub surname is a mistranslation of the original name "Yagami". Kari's Japanese name, "Hikari" (ヒカリ?) means "light", a unique parallel with her crest's name. Also, her original full name "Hikari Yagami" translates to "light of the 8 gods", a possible reference to the number of the DigiDestined in the first season.
During Adventure, Kari and T.K. Takaishi begin to work as their own microcosm-type team, oblivious to several of the problems of the rest of the group. T.K grows very protective of her, as shown in My Sister's Keeper and Piedmon's Last Jest.
In Adventure 02 Kari once again hangs around (and often teams up with) T.K. during several occasions. She also uses him sometimes as a source of experience to discuss with, as the two have dealt with Digimon far longer than the others. In the "Present Day" segment of Digimon: The Movie, Digimon Adventure 02: Digimon Hurricane Landing!!/Transcendent Evolution!! The Golden Digimentals, she said that part of the reason she brought TK with her to visit Mimi was to make Davis jealous.
Kari is aware that Davis has a crush on her, and sometimes exploits that to get him to behave. However, she does see him as a good friend and valuable ally.
Kari was asked out to the beach by Davis, but turned him down
In Kari's Digimon Girls Festival song "Reflection", the person Kari addresses is most likely T.K., as he fits all of her descriptions. In the song, Kari acknowledges that he has been protecting her and has known her for very long, since their youth. She describes their relationship as "too cute to be called romance".
The three Degidestined kids from Hong Kong also called the Poi Brothers, also have a crush on her when she and Izzy arrive to their town.
