Y/n E. Gadd, grandson of Luigi's professor friend is his grandfather's greatest lab assistant. They study the behavior of various ghosts at various haunted locations. Although, Y/n stopped when some ghosts attacked his grandfather. After that, with the professor's permission, he started collecting any and all of the bothersome spirits that intend to do harm, and let his grandpa observe the aggressive spooks in a more... contained environment. After many years of ghost hunting, Y/n comes across an unusual haunted mansion... (I don't own anything! Except for my own drawing.)
