Hikari Yagami

Hikari Yagami is a character in the anime and manga series Digimon Adventure, Digimon Adventure 02 and Digimon Adventure tri.. Hikari is a DigiDestined, partnered with Gatomon, and embodies the trait of Crest of Light. She is the younger sister of Taichi Yagami.

Kari is the sweet, innocent and cheerful younger sibling of a Digidestined. She always looking for the best side of people and doesn't fight but can be serious in drastic situations. Kari is also selfless, as she would put the safety of others before her own and doesn't want to trouble others. 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. As a teenager, Kari is whimsical, but is still a down-to-earth person.

Kari is shown to have a unique connection to light and darkness, which seems to be related to her associated trait of her crest. 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 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. Dark Gennai noted that Kari's connection to Tai and her 'sensitive' nature made her easier to 'break', and the shock from Tai's apparent death caused her negative emotions to influence the creation of Ordinemon.
