Kai Hwang

Kai, who has long black hair and brown eyes, is human. He lived in South Korea with the Light*Dark Guardians.

Kai was called upon by the Light*Dark Guardians to help an American witch named Irisa Feywin locate an littler girl that Khlyen is chasing, and they must ensure her safety. They succeed in finding her, and he vowed to protect her.

After falling in love with Irisa, they got married and had two children: a daughter named Miao and a son named Lu Si. They resided in Seoul, South Korea, until Amaranthine turned 8 years old. At that time, they relocated to Hilo, Hawaii, because Khlyen discovered where they were living.

By moving to Hilo, Hawaii, they aim to ensure Khlyen cannot locate her. Their intention is to remain there until she completes her schooling. Amaranthine plans to pursue a movie with Miao and Lu Si, allowing them to attend the University of Hawaii at Hilo. During her college years, while dating Dylan Hale, Amaranthine was proposed to, and they planned to marry. However, before the wedding, Khlyen discovered her location and killed Irisa and Kai.
