Phan (판) is Hyuna and Hyun Woo's segyein guardian.

Phan hasn't been shown much, but one piece of information that is released in the official artbook is that Heperu (Luka's guardian) has an attraction to him, in the same way that Luka is attracted to Hyuna.

The most superior race among the species of the world. It is a form of life that cannot be found in space. He has the aura of an aristocrat, but since he is from another world, they don't take him seriously. They are different from other living beings and are not easily authoritarian. The reason he introduced himself as a Guardian in Anakt was instead of showing off his human pet, it is said to be a type of sponsorship. Since they have no interest in their pet, they don't even look at Anakt. He is considered a legend in the academic world, he focuses solely on academic objectives and considers science as art.
