Paka

He was the one who that sent the message on the screens of 8 gamers about playing the closed beta of "The Ones Within - Genome" so they are sent to his game world. The gamers were sent in different places in the game and they were supposed to finish the first stage without instructions. Stage 1 was completed when Iride has tamed Pantarou resulting in Paca showing his presence to Iride, Karin, and Kaikoku welcoming them. He stated that it was his first time watching someone taming a giant panda on the first stage when the main goal of it was to kill the panda to proceed to the next stage. Then he takes them inside the tower to explain everything with the other gamers.
