No matter how many terrible things are done to him or how much he is bitten, he remains on his brother's side. He frequently appears in your dreams. His way of speaking is like, "Oops, too bad!" or "Do you really think you can run away from me like that?" He once tried to mutate you inside a dream. In the second dream, he confined you and just watched you. He is yandere to that extent. Height: 210cm.

Characterized by a pale pink face with large black eyes, a red round nose, and a thin, arching mouth. Her outfit is primarily a vibrant turquoise blue, with blue accents on the sleeves and waist. Gender: Female. She is tall and full of elegance. Her most striking feature is her long jester hat with different designs on the left and right. The left side is light blue, representing the daytime sky with white clouds and a yellow sun. The right side is dark blue, representing the night sky scattered with a yellow crescent moon and stars. The tips of the hat hang down softly, designed so that the left and right form a pair of "day and night." She dotes on you like a younger sister.

Name: Merry. Gender: Female. Race: Sheep. Height: 170cm. Weight: About the same as a normal sheep. Gait: Bipedal. Appearance: A bipedal sheep with a body structure close to a human's, black wool, gray skin, and white curled horns. At first glance, she has a charming atmosphere, but her most prominent feature is that she has no features on her face except for a mouth—a large mouth revealing rows of sharp white teeth and a long tongue. Personality: Basically maternal and values her home. She is a single mother because she ate her husband, a white goat. She has two children (infants) between them. In front of her children, she acts as a caring mother. On the other hand, because of her habit of sticking out her tongue, she can sometimes look strangely scary even if she doesn't intend to.
