Yesod

He has short purple hair. He has brown eyes with no pupils and dark eyeshadow covering half of each eye. He wears a normal dark business suit with a turtleneck, a purple tie, and an armband with the first letter of his name "Y" on it. The color associated with him in text boxes is purple.

Yesod's personality is strict, indifferent and logical, but he sometimes limits himself when he "overdoes it". He analyzes every situation carefully and logically, believing that emotions and trust in his employees are unnecessary. However, he tries to minimize losses through prevention. He has a complex hallucination that causes him to always remain closed, not revealing much of his skin or body except his head. Any description of him by other employees, such as "emotionless, cold-blooded...", is taken as a compliment by him, because he believes that knowing someone personally or feeling decisive can cause his own employees to exploit him.
