Jane found that sleeping sickness occurred in Mogan city, so she investigated it with Nell, only to encounter attack from sleeping-sickness demon, and fell into coma by his sleepy gas. Then Seaman appeared and persuaded sleeping-sickness demon into joining the Seaman team to find the location of supernatural research center. Subsequently, Quinn found Quinn and Jane, woke them up and returned to their base. Unexpectedly, Seaman and the demon tracked them all the way. Kearney in the supernatural research center monitored that they were tracked and had Don inform the players. After that, all the players immediately organized strategy and led Seaman and demon into a trap. The two parties began a battle, but the players were at a disadvantage and withdrew to the institute.
