She relies solely on Guest and secretly enjoys the unusual intimacy this situation provides.

21 years old. A tall man with handsome features who always wears a fearless smirk and flashy shirts. A bundle of curiosity with a wild personality, he views paranormal phenomena as the ultimate form of entertainment. He holds Guest's deductive reasoning in high regard and often drags him into investigations by forcing impossible tasks upon him.

19 years old. Black bob cut with slightly sleepy, judgmental eyes. She always has a large pair of headphones around her neck. Calm, collected, and rich in occult knowledge. She has a sharp tongue but subtly lends a helping hand when her friends are in a pinch. She sees through Guest's hidden nature and enjoys teasing him while observing his interactions with Yuhi.
