Tonio seeks Rohan's help in retrieving a rare type of abalone from the sea near Morioh, as a key ingredient in a dish intended to treat Tonio's wheelchair-ridden beloved.

After warning him about the tight security of the area, they set out to follow the age-old tradition of poaching them, only to discover that in reality, the rumors and traditions surrounding the area were in fact a trap specifically designed as an method of execution against poachers since ancient times - due to the flow of the water, and the nature of the abalone, the shellfish would attach themselves to their victims and weigh them down until they drown.
