A visual novel about four college sophomore psychics investigating ghost-related incidents about the United States. When they're not studying for midterms, of course.
Psychics are detrimental to modern technology; even when not using their abilities they emit special radiation that permanently damages circuitry. This is why Psychics live secluded in the Campus nestled deep in a forest in rural Indiana.
In order for Psychics to operate outside the Campus, they wear special body suits that dilutes deleterious side effects. They are designed to be worn underneath regular clothes and are resistant to the effects of known Psychic abilities.
Less than one hundred such suits exist, meaning access to the outside world is a high-value commodity. One chiefly reserved for field agents, ghost hunters: the Letters and Numbers.
