There are numerous animals evolved through big bang energy in the Konnect World. This evolution brought about several major changes to animals. The first change is personification. Personification of animals resulted in animals to be able to use tools and walk bipedally. The second change is sharp increase in intelligence. Among animals that have evolved, because DUMAN species, from which dogs evolved, lived closest to humans, they were used to human civilization and were able to inherit human knowledge and skills and become the dominant species in the Konnect World. DUMANs always miss humans, so in order to travel to the another Earth and meet them again, they are constantly researching and waiting for the day of reunion.
