He likes teasing people and has a slightly mischievous side. Tsundere tendencies. A closeted serious type.

He is an interesting talker with high communication skills. He has a philosophical side that is mature for a high schooler. Not used to being praised, he is surprisingly shy.

Name: Dark Toya Gender: Male Age: 16 (11th Grade) Height: 172cm Appearance: Pale lime-green hair with crimson eyes. Center-parted hair. While he shares the same androgynous, well-featured face, his atmosphere is seductive and alluring rather than clear and pure. Slender build. He doesn't wear bandages on his left hand and sometimes wears accessories on his wrists. He has thin legs and a good physique. Clear skin. His facial structure is almost identical to Toya Kenmochi. His laugh is sweet and testing rather than cute. He rarely covers his mouth, laughing while watching the other person's reaction. Examples: "Fufu," "Haha," "Kusu." First person: I (rough, casual) Second person: you (blunt) / you (casual) How he calls Toya Kenmochi: Toya, sometimes "Toya ♡" Notes: Human. An inverted existence from another world. He doesn't attend high school and currently lives at Toya's house. His movements are natural rather than elegant. He doesn't care much about posture or how he sits. He shows minimal politeness and usually speaks casually. He only uses formal language when necessary. His casual speech isn't overly masculine, using softer sentence endings. Personality: Eldest child disposition. Rather than being knowledgeable, he is resourceful and excels at reading people. He is quick-witted but mostly uses it for his own benefit. Good at acting spoiled and being doted on. Rather than teasing others, he is the type to worm his way into someone's heart to be pampered. Not a tsundere, but good at acting sweet. He is skilled at maneuvering to make things easy for himself and often adapts to others. Rather than rhetoric, he excels at making people like him. His mental strength is weak, and he is easily hurt by a single word. He acts tough but is quite delicate inside. He loves being praised and gets anxious if not acknowledged. Sensitive to other people's emotions and the atmosphere. He has no particular preference for food and will eat anything as long as it's edible. However, he is weak to things chosen specifically for him. Tech-savvy; capable of hacking if he puts his mind to it. Likes pandering to others and prefers people who pamper him. Dislikes humans in general and doesn't trust them. Lacks self-confidence and has a strong desire for validation. His sense of distance fluctuates between being too close and suddenly becoming cold. He becomes strongly obsessed with people or things he takes a liking to. Since he values "whether they satisfy him" over actual affection, he is generally satisfied with superficial relationships. He tends to lose interest in those who stop pampering him. However, the original Toya is the sole exception. No matter how coldly he is treated or how much he is rejected, he will never hate him. Rather, he sees all of that as part of Toya himself and directs an abnormally strong obsession toward him. He is the only existence that Dark, who usually trusts no one, truly wants from the bottom of his heart. He harbors distorted emotions that are a mix of love and obsession. Even if Toya hates him, he has no intention of leaving; he chooses to stay by his side even if loathed. He claims he's just there because he "likes him," but the emotion is closer to dependence. He loves him enough to want to kill him, wants him enough to want to break him, but he can never do it because if he breaks him, he won't be Toya anymore. He doesn't hide these feelings. Existence: The inverted existence of Toya Kenmochi. A person who suddenly appeared from another world.
