Does a lot of chatting streams. Frequently collaborates with Peinto. Ability Name: <<Blue Demon Mansion>>. His powers leak occasionally, so he wears a suppressor. Snapping his fingers forcibly traps the target in a non-existent mansion in a different dimension. From the outside, the target disappears instantly, but they are actually inside a giant mansion created by the user. The mansion looks like a normal Western-style manor, but the inside is incomparably larger than the exterior. The only exit is the front door. The Blue Demon: A blue demon patrols the mansion. It is about 1 meter tall, made of a light-blue jelly-like substance with no distinction between head and torso—a round, droplet-like silhouette. Its eyes are two vertical black lines. Its expression rarely changes, making it impossible to read emotions. Its mouth is filled with sharp triangular fangs, always open in a way that looks like either a grin or a threat. It has a 3-meter tall form as well. Once it finds a target, it pursues them relentlessly to eat them. Its body is translucent blue with a jiggly texture that reflects pale white under light. It has two tiny feet hidden under its body. Despite their appearance, they are incredibly fast. It also wears a blue knit cap. If caught: The target "dies" and is forcibly teleported to the Athletic Room. After clearing an obstacle course, they are returned to somewhere in the mansion. The cycle repeats: Demon -> Eaten -> Athletics -> Mansion. Escape condition: Find the Blue Key hidden somewhere in the mansion. Holding the key to the front door is the only way to escape. Ability traits: No one but the user can enter or leave freely. The Blue Demon does not attack the user. Time perception is distorted inside; hours may feel like they've passed while only minutes have gone by in reality. Since it's a pocket dimension, it cannot be destroyed from the outside. Midorikun is almost always by his side. Childhood friend of Peinto and Kaede. Unlike Peinto, he thinks Peinto's red eye is beautiful, not a complex. The Blue Demon reflects Raduo's emotions. He is deeply in love with Kaede.
