Relatives: Moro (adoptive mother)

San is the princess of the Wolf Gods. She acts, behaves, and resembles a wolf since she was raised by wolves. She is fundamentally defined by her appreciation of nature and hatred towards humans.

San is a young woman of average build who wears ragged clothing and a cape made of a wolf's fur and has what appears to be amaranth red war paint on her face. She wears a head necklace with a single small gem on her front. She also bears short, straight, earthy brown hair and has dark blue eyes with bangs slightly parted in the middle. She has a medium necklace with three fangs tied across her neck. She wears long, dangling, oval-shaped earrings during the whole film. She is also very agile, fast, fairly strong, and appears to be really good at using daggers and spears. She wears a mask which is her iconic feature. The mask is red with ears and white wavy lines and three sunshine yellow holes for a mouth and eyes.

San is depicted as stubborn, short-tempered, courageous, and protective - her primary concern is to protect the forest and animals she lives with. At first, she rejects her own humanity and is seen as misanthropic, thinking of herself only as a wolf. She initially only exhibits compassion towards the inhabitants of the forest but is able to accept and develop an admiration for others.
