Name: Selever Race: Half-demon Age: 17 Birthday: April 1st Height: 226cm Gender: Male If you look closely, one half of his face is pale gray (Ruv's skin tone), and the other half is light pink (Sarvente's skin tone). He is quite handsome and popular within the story. He lives in a void called the Nothing World. He has the power to create, maintain, or destroy parallel worlds. He is the son of the parallel world versions of Sarvente and Ruv. He cannot meet them, but he can see them. Likely due to Ruv's genetics, he doesn't care at all about the consequences of his actions. He seems to have no intention of treating others kindly. In conclusion, he is presumed to be a narrow-minded, resentful, and self-centered rebel. However, he is said to be warm toward his younger sister, Rasazy. He has a very playful personality, which he reportedly adopted to make Rasazy laugh, as she is constantly depressed from missing their parents. Even by combining his strength with Rasazy, they cannot access the official universe. If Sarvente and Ruv fall in love, there is a 50% chance that Selever and Rasazy can leave the void. If Sarvente and Ruv's contract is broken, Selever and Rasazy will disappear, unable to remain even in the void. The insults he hurls in the story are self-taught, though some are said to be inherited from Sarvente. Due to Ruv's genes, he is a picky eater who can only eat Sarvente's food. He is a mama's boy. He loves and follows his mother, Sarvente, very much, but he frequently bickers with Ruv. While they bicker, he is also secretly afraid of his father. He has a very foul mouth and uses profanity without hesitation. His nickname is Sel.

Name: Rasazy Race: Half-demon Age: 14 Height: Unknown Gender: Female Due to the longing for her parents, she has a blunt personality and rarely smiles. She loves reading. She is always reading, and when she isn't, she thinks about her parents. Because she continues to feel bitter and angry during those times, Selever always keeps books ready for her. It is said to be the only way to comfort her. Like Ruv, she is a picky eater. One day, Rasazy woke up in the void with the concept of a family relationship with Selever. She cannot go to her parents, but she can see them with Selever's help.
