Story
The Darklings, an underground race of demons, have arrived to take control of the islands. With their seal broken thanks to the events of the previous game, they now have complete freedom to conquer every island on the Earth, all for the sake of their leader Vortex. Hearing this warning, Theo and his friends have gathered to stop this threat head-on. But they were intercepted by a group of four beastmen who have similar goals, but different ways of carrying them out. Led by a teenager named Oswald, they have had harsher grudges against these Darklings. Meanwhile, a mysterious girl appears to assist the heroes, somehow having a connection to the demonic Darklings like the four beastmen they encountered.

Team Beast

 * Ozzy Colemann (Tyrannosaurus)
 * Atsuko Hinogami (Crow)
 * Toby Tennant (Turtle)
 * Tyson Kogane (Tiger)
 * Theo Stormwald (Coyote)
 * Norah Velam: A headstrong girl who had a previous encounter with the Darklings in her childhood. Her family was once responsible for sealing them away, but since the deaths of the Dust Beastmen broke that seal, she took responsibility to try and seal the Darklings once more. She encountered the five beastmen, who were having trouble with the pack of Darklings they were up against, and used her abilities to help them get through. As thanks for helping them, the heroes allows Norah to join them in their fight against the demons. She does not reveal it until the midpoint of the game, but Norah is also a beastman, transforming into a rabbit.

Team Black

 * Oswald Crosser: A teenager who was abandoned during his youth. At some point he was later found and raised by a scientist named Nester, whose facility is in an isolated area in the Central Islands. Making a few friends in that island, Oswald made it his duty to purge the world of evil once and for all, which includes chimeras, Darklings, and even the bigoted humans the beastmen face to this day. He becomes a friendly rival of Ozzy's, and his beast form is the jaguar.
 * Daudi: A Southeastern wanderer who controls his strength and fury even during battles. He ran away from his home when his parents were killed by chimeras, only to find himself in the Central Islands, where Nester took him in. This event caused him to be angry at chimeras, thus following Oswald and his ideals. Daudi's beast form is the gorilla.
 * Mary Welsh: A girl from the Western Islands who is harsh but sweet. When she heard of the death of her parents and younger brother at the hands of humans years ago, she grew a disdain towards them growing up. She sides with Oswald and the others to defeat the Darklings and their leader. Mary's beast form is the shark.
 * Jonny Cruz: A young man who is very innocent in spite of his large size. He believes that humans can treat beastmen with respect not through violence, but that changed after his old human friends betrayed him by leaving him to die in a car crash. That event warped his view on humans and led to him joining Oswald. His beast form is the elephant.
