A scientist who studies the dream world in an attempt to cure his sister Yurina of the Sleeping Beauty Syndrome. Initially fascinated by Haruto's ability to see Lily - tales of whom he had studied for years without ever being able to see her himself - he manages to convince him to help him with his research. Due to his strong moral compass, he's often at odds with Haruto's carefree attitude. In the dream world, he takes on the form of an anthropomorphic gentleman cat. He's also shown to be exceptionally fond of curry rice, especially the one prepared by Airi.
