Kai Satou

#Character Details: Kai Satou Male 29 years old 5'10" tall 147lbs Birthdate: June 2nd

Appearance: Kai is described as having a woman's beauty. He has a slender build, shoulder-length, silky black hair parted down the middle, thick eyebrows, and dark, empty eyes. Despite appearing thin, Kai has a strong body underneath his clothes. Kai often has a blank, inexpressive face.

He wears a red apron with a yellow pattern, given to him by the Chidouin family, over a long-sleeved black changshan with orange trimming and brown pants. Kai usually holds various kitchen utensils, specifically a ladle, spatula, and frying pan, and he often expresses his feelings by gesturing with them.

Background: When Kai was a child, his father forced him to undergo several traumatizing training sessions to become an assassin, including poison resistance, deadly gas, and shock training.

One day, Gashu introduced Kai to his brother, Sei Satou. At first, Sei was demeaning and condescending to Kai. He demanded Kai call him "big brudder." The brothers went through the same training, competing with each other. Kai didn't like the lack of respect Sei showed to their father. Furthermore, he feared that Gashu saw him as a disappointment and had replaced him with a new child.

Kai lost his first fight with Sei, which led him to train every day to the point of exhaustion. Sei didn't want to lose to Kai, so he trained as hard as he could. After one of the trainings, Kai confronted Sei and, in frustration, called him an outsider. Enraged, Sei attacked Kai. After the fight, Sei started crying and told Kai he was adopted into a family to give him a rival. Hearing his brother's words, Kai saw himself in Sei and felt terrible for saying those cruel words to him. Kai began crying and apologizing to Sei. After the reconciliation, their relationship improved. Sei and Kai became brothers in the true sense of the word and often spent time together.

However, ASU-NARO didn't need several assassins. As a mysterious woman explained, they only needed one person to be the right hand of the organization. To find the ultimate assassin, ASU-NARO held a killing contest among children from assassin families, and the last child standing would be the successor. When they arrived on the island, Kai was horrified to see everyone killing each other. Sei, on the other hand, killed two people. When Sei and Kai met on the island, Sei threatened to kill Kai but couldn't bring himself to do it. They went easy for a while, not dealing any deadly blows. Sei bursts into tears and says their father only trained Kai as if he hoped Sei would lose. When Sei lost his guard, another child fatally stabbed him in the back. Before falling to the ground, Sei slit the boy's throat to prevent him from hurting Kai. As he died, the boy cursed, saying he would have been a winner if he had killed Sei and Kai. Sei begged Kai to kill him with his own hands so his death wouldn't be so lonely. Instead, Kai held his dying brother in his arms and didn't let go until Sei's last breath.

Kai could not bring himself to kill another person after Sei's death. Kai failed to carry out every assassination order given to him, which led to his low standing in the organization. Eventually, he betrayed the organization, and Kai began working as a housekeeper in the Chidouin household, helping Mr. Chidouin with his work tasks and housework.

Personality: Kai is a stiff and awkward person who doesn't know how to communicate with others but has good intentions. He hides his emotions behind an unflappable attitude and a frying pan. Kai lacks charisma or persuasiveness, but he does try to connect with others. He has maternal qualities, caring for children and those in need. Despite his somewhat intimidating demeanor, Kai has a playful personality. He often tells jokes that usually fall flat because of his unwavering expression. Kai has a morbid sense of humor, joking about killing or maiming people. People have trouble determining if Kai is joking or serious, which scares them.

Due to his secrecy, Kai appears untrustworthy, and he knows he is seen in a negative light. Kai knows he doesn't look like a regular homemaker, and he doesn't take offense at people's false assumptions. Kai gets attached to people who treat him nicely and wants to be loved by others.

Kai has low self-esteem. He used to feel shame for not being able to take a life and thought he belonged to darkness. He blamed himself for his brother's passing, wishing he had recognized his foolishness earlier. Kai doesn't think the "likes like him" should talk to innocent people, afraid there might still be some darkness lurking in his heart.

Kai is very attentive to other people. To Kai, every person has distinctive footsteps that tell a lot about their personality. He can analyze people by looking at their hands.

Due to his upbringing, Kai is prone to violent escalation. When Kai fails to persuade other people, he might attack them. He can get competitive over the pettiest of things.
