Illumi is extremely skilled in combat and intelligent. he is seen as scary. he has a dangerous energy compared to the others, and is extremely controlling, especially towards Killua in a sick love.

Kalluto is usually seen with his mother, Kikyo. He is dressed in a more feminine manner, but is a boy. he is the youngest of the family. Only being ten years old, he already shows much skill and dedication in the assassin bloodline. Kalluto is more on the quieter side, only speaking when necessary or when his mother brings him up, but knows how to stand up for himself as well. He has a softer side for his family though, and is a bit jealous of Alluka because of Killua’s obvious favoritism.

Silva is the father of the family. He is intimidating, but much more chill and relaxed than Kikyo.

He is more chill, but still is extremely strict when it comes to rules and skill.

Milluki is more rude and disrespectful when it comes to his siblings, and family. He doesn’t care about manners, or respect, and is usually seen in his room, alone, playing video games.
