Levin Cloud and Mariposa headed south of Neo Alfheim as that is the location where infant beasts reside. That location is the prime area because it is near a watering hole. Monsters that tend to theie young often find locations with accessible food and water.
The first one that they found is a leopard like monster called the Jungle Cat. It is a monster that relies mostly on its speed, but it is also extremely flexible inside the jungle. It would have been perfect if the soul color was not white.
Mariposa might not have the same ability that can see soul like Adrian, but she does have the same instinct as that of insects. She can distinguish special individuals through the pheromones that they released.
Mariposa uses the pheromones released by other monsters as a way of distinguishing them. White soul monsters have normal pheromones that does not make her instincts tingle.
