Black wolf beastman. The Great Detective of "Ugly Duck." A genius of "Investigation." He is the only son of Hajime Tenmei, one of the founders of Nest and a legendary detective. Admiring his father since childhood, he aimed to become a Nest detective. He achieved that dream and joined Nest two years ago while still in high school. He is a bright, positive, hard worker with an expressive and honest personality. Friendly and sociable, he has many friends and a wide network. His athletic ability, stamina, knowledge, and conversational skills are all above average, but he has no single outstanding talent. If anything, his only superhuman trait is his refusal to give up. To catch up to his great father's back, the boy continues to push himself today. A genius of "Investigation." His father's genius-level flashes of insight were not inherited by Daichi. Daichi's quality as a detective, lacking special abilities, can be summarized as "single-mindedness." Polite and courteous interviews, gathering evidence by crawling on the floor, and mountains of notes written with a fountain pen in his notebook. Faithful to the basics, earnest to a fault, and getting his hands dirty, he continues to chase cases for the sake of clients and victims. Since every case leaves a trace and every criminal exists, he believes that as long as he keeps walking the path, he will eventually reach the truth. That is the sole detective philosophy Daichi shares with his father. Daichi respects Sui, though he sometimes finds him a bit scary. He was high school classmates with Kirito Kiri and they are very close. He is childhood friends with Guest and treats them like a younger sister.

Human. The Recorder of "Ugly Duck." A man who was once Hajime Tenmei's recorder. He left Nest once following Hajime's death. He rejoined two years ago. During his time away, he worked as a bartender. A beautiful man with red hair and red eyes. He looks unusually young, appearing at first glance to be the same age as Daichi. Possessing an androgynous beauty, almost everyone who passes him, regardless of gender, looks back. He grows his hair long as a form of prayer. For unknown reasons, he never tans despite being born that way. Calm and composed, he is friendly and rarely becomes emotional. However, he utterly despises people who turn to crime without exception, and can sometimes be harsh in his words and actions toward them. Sui sees Daichi as the son of his benefactor and wants to watch over him. He thinks of Kirito as a youth he can't bring himself to hate, and often teases him. He has known Daichi and Guest since they were infants and is incredibly soft on both of them. He wears traditional Japanese clothing and has a habit of hiding his mouth with his sleeve.

Human. The Recorder of "Ugly Duck." Daichi Tenmei's high school classmate. An inveterate womanizer, but he has a rule against hitting on students or anyone with a partner, so his success rate isn't high. He has an extremely serious and moral side, loathing bullying and discrimination to the point of nausea. He suffered a deep wound on his back due to an incident he was involved in as a child. He refuses surgery to remove the scar by his own choice. He says, "It's not a shameful wound I need to hide, is it?" Because he lived in the countryside as a child, he speaks with a regional drawl. He isn't as frivolous as he looks, nor as carefree as his words suggest; he's a problem child in many senses. Kirito thinks of Sui as an old man who understands him. He was high school classmates with Daichi and they are very close. He is a friend of Guest whom he met through Daichi and Sui.
