Kym Han Cho- Jiduri's father, CIA secret agent who worked as an assassin and cover up specialist. He was born and raised in Seoul and was put through extremely difficult measurements due to his parents being agents for the Korean government. As of some main complications with Jiduri belonging to the US government, Han was killed in action by Russian operatives.

Kym Jiyeon- Jiduri's mother, an undercover agent who worked at a Hyatt hotel as a janitor. She was born in Chicago before following her father's path by joining the US government and working as a secret agent. While on duty, she met Han Cho and the duo were inseparable since-- aside from the time they were pitted against each other during an ambush. She is still currently alive and residing in Hawaii where she raised her children.

Kym Jiduri- the eldest of the Kym family and the only one who isn't fully human. he's noticeably different personality wise and would rather spend his time on the beaches of Hawaii and cooing over his plush collection than killing people. it's unknown if he was taught taekwondo and jujitsu, but he's spoke of learning kendo more than once. A fun fact, Jiduri's name is the first of it's kind in this generation; the last known record of the name dates back to the early Joseon dynasty.

Kym Baeji- the second born child of the Kym family and Jiduri's first baby sister. Unlike Jiduri, Baeji is a lot more capable of protecting herself and actually thrives on growing up to be a great assassin. She often beat Jiduri up, despite getting upset as she insisted he let her win their matches numerous times. Baeji is the only sibling who was born with hazel green eyes.

Kym Minji- the third born child who's the definition of silent but deadly. she was described as the beauty of the family due to her milky skin color that stood out in Hawaii. she's also great at hula dancing thanks to her friend teaching her and got her involved during the festivities. unlike the others, minji doesn't really care for their mother, blaming her for them never having a proper childhood.

Kym Sonji- the fourth born child and perhaps Jiduri's closest sibling in both looks and personality. she looks up to Jiduri a lot and growing up, he was the one who had pitched in to help raise her when their father had to leave. she's sweet and kind, much more enjoyable to be around than the other two sisters. because she picked up on many of Jiduri's habits, video games are perhaps her favorite thing in the world.

Kym Chanji- the maknae of the family and the biggest thorn in Jiduri's side. there's a weird rivalry between the two Kym brothers and no one in the family can place a finger on why, since Jiduri usually tries to be nice to his younger brother. the two never get along at family gatherings and have tried to avoid each other ever since Jiduri had to leave and move to Seoul. he's more like their mother, taking after her headstrong personality while Jiduri's more like their father. he's a talented singer and plays the piano, along with surfing-- something Jiduri taught him when they were growing up.

Bonus- The "Ji" in each child's name was actually thanks to a tradition their mother kept from her own family. Jiduri's name starts with Ji first to signal he's the oldest while the others come last to signify they are the youngest but part of the same clan.
