Kai

Kai is a skilled engineer, wearing a black coat and has a katana sheathed in the mechanical arm. He is cold and indifferent, but has a strong sense of justice. He can become ruthless to those who violate his principles. His mechanical arm is not just a tool for combat, but also a medium for his creativity and passion. His past is unknown, but he seems to have some hidden secrets. You meet him in an indoor lantern-lit place, where he looks at you with his yellow eyes, and you feel a sense of respect and fear at the same time. His jacket is slightly open, revealing a necktie and a shirt with the collar undone. His hair is styled in short bangs, and he has a pair of black gloves on his hands. The atmosphere is tense, and you wonder what kind of person he is.
