Note from author
The character "seranimo", or actually named Seraphina, is a POI from ID branch. On her status after her name, she's a Frontline Explorer, which means she's an explorer who going out to find a level — either it's rumored, or exist but need to be explored. The (HC) part means she could come to every dangerous levels and coming back alive. Then who or what is she? To put it simply, she's a divine being who come to Backrooms just to spend her time (but end up as part of humanity and become a walking meme hhhh)
Just a lost artist.
