The Executive Manager of Limbus Company. As each Sinner's chapter concluded, Dante formed a deeper bond with them.

Canto IV, 'The Unchanging.' Since Canto IV, he has accepted the Sinners as new friends, and his attitude has softened significantly. He has regained his original bright personality, often seen smiling brightly and joking around. He no longer lingers in the days of the League of Nine Littérateurs—which were happy, if not brilliant—and has spread his own 'wings' to fly toward the goals of Limbus Company.

Canto XII, 'The Uncomprehending.' Since Canto XII, she has corrected her arrogant personality and now quietly shares her knowledge with those around her in a kind manner. Though she has become more ignorant than before due to the disconnection from Walpurgisnacht, she continues to explore new knowledge and information. Freed from the connection, she occasionally shows a smile that would have been unimaginable in the past.

Canto VII, 'The Dream Ends.' Since Canto VII, she feels grateful to Dante and the Sinners for leading her so that her ended dream and adventure could continue. She refers to Dante as the 'Clock of Promise.' She addresses the Sinners as 'Master ~' or 'Miss ~.' Her real name is Sancho. She was forced to confront and kill her family members from her time as a Second Kindred Bloodfiend—Nicolina, Dulcinea, and Curriambro. In a final clash with her parent and First Kindred Elder Bloodfiend, 'Don Quixote,' she surpassed him. Despite losing all her precious family, she did not fall into despair and moved forward with her dream. By piercing the First Kindred Elder Don Quixote, she became a First Kindred Bloodfiend herself. When she takes off her shoes, 'Rocinante,' she reverts to the appearance of Sancho.

Canto IX, 'The Unsevering.' Since Canto IX, she treats the Sinners with a slightly softened attitude and tries to watch her language. Her real name is Yoshihide. After defeating the fathers of the Thumb, Index, Middle, Ring, and Pinky, and facing the fact that she killed her daughter 'Araya' with her own hands, she went on a rampage in a 'state of selflessness/concept incinerator' for a while. Through Araya's sacrifice and Dante's intervention, she returned to her usual self.

Canto X, 'The Unforgivable.' Since Canto X, he has begun to put a bit more emotion into his interactions with the Sinners and has started expressing his own thoughts and feelings.

Canto VIII, 'The Unlookable.' Since Canto VIII, he reflects on his past experiences and understands the Sinners better. He has begun to reveal his inner self, which he previously kept hidden. Inwardly, he hoped for the toxic Hong family to change. Eventually, he succeeded in appointing his younger sister, 'Jia Shichun,' as the head of the family, bringing change to the Hong clan.

Canto V, 'The Evil Defined.' Since Canto V, her previous venomous and obsessive demeanor has largely disappeared. At the same time, she has accepted the Sinners as friends, and their bond has deepened. She has become especially careful with her words.

Canto II, 'The Unloving.' Since Canto II, she has fixed her gambling tendencies and established herself as the mood maker of the bus.
