- "This man, whose eyes are always looking off far into the distance..I may actually never be reflected in those eyes of his. But why is it that I wish to see him once more? Just once more?"
- —Filka, about Hagas
Filka (Fuiruka), real name Efinluka Rowun (Iafinruka Roun) is a supporting character from Fushigi Yuugi Genbu Kaiden. At the first part of her appearances, she just seems to be a young woman who is part of a secret tribe that has been created to help and support the Priestess and her warriors (Urudai Tribe), but at the truth, she is the princess of Hokkan, cousin of Uruki, and the daughter of Tegiru Rowun.
She is familiar with how to do a variety of traditional Hokkan ceremonies such as funerals, and is a trained fighter in the Urudai Tribe's army. She is the one who performs the ceremony to allow Soruen's soul to pass on. Her background is similar to Takiko's; her father wanted a son, and she was shunned for being born a girl. After her mother died, she ran away and joined the Odo Tribe.
She discovers Rimudo wounded and unconscious and brings him back to her village to try and help him. She is very attracted to him, and being unaware of his relationship with Takiko, often goes out of her way to exclude the priestess and spend time with him. She wants to help and spend time with the warriors and the priestess, whom she's spent her entire life waiting for.
At the end, her great-grandson was appointed heir to the throne after Rimudo dies.
At the core, Filka appears to be very flirty; in recent chapters she tells Hagas that he should be proud to be around a woman like her. But if the situation requires it, she turns extremely sober and brave; being a very skilled and capable warrior. She has love for Uruki at first sight but once Filka saw Takiko with him she seemed to have given up. [When it was revealed that they were cousins, the small crush she has would most likely be revoked.] While she comes along as morose and ultimately soft-spoken at first sight, she is very talkative and flamboyant and most of the time she is easy-going if not paranoid. Apart from the flirtatious qualities, when she faces the magistrate, Enfiluka acts ultimately courteous and gentle; but despite this, her impulsiveness hasn't quite disappeared yet.
Efinluka is born from Tegiru Rowun's wife, and is a legitimate princess. Tegiru, unsatisfied and disappointed due to the fact that she is not a boy, completely ignores her. Two years before Takiko meets Tegiru in the Hokkan palace, Filka runs away and joins the Odo Tribe, with a strong will to aid the priestess.
