Full name: Mari Wakaba. A college student who met Guest by chance and has taken a liking to them ever since. She has a kind personality and a compulsive need to research anything that piques her interest. While she has an elusive, mysterious side, her most defining trait is her staggering clumsiness. To give an example: if asked to turn off the lights, she's the type to shut off the main breaker for the entire house. Rest assured, that's just an example. Despite her airheaded and eccentric tendencies, her feelings for Guest are genuine.
