Sadeena

Appearance
In her Orca beast-man form Sadina's figure is large in all directions although she is not fat. She is simply part of a giant race of beast-men. She is average sized for her race. In her human form she appears to be like a beautiful traditional Japanese-style woman with long black hair, fair skin, and face that would rival even Raphtalia.

Slave Supremacy Arc (introduction)
Sadina was a slave of the Slave Merchant in Zeltbull. She was purchased along with three others from Raphtalia's village, and although she wasn't from the village, she claimed to be a wanderer who stopped by it occasionally to visit Raphtalia's parents. After the fight with the Zombie Dragon, it was revealed that she maintained her Orca beast-man appearance through magic, but her real appearance was that of a beautiful traditional Japanese-style woman with long black hair, fair skin, and a face that would rival even Raphtalia. Sadina is later identified by Gaelion as a shrine maiden (add more from c185)

Sadina would often tell the people of Raphtalia's village that if someone could beat her in a drinking contest she would marry that person. As it turns out, she is later defeated by Naofumi when he eats a Lucor Fruit. True to her word, Sadina falls for Naofumi, but she waits for Raphtalia to return from her Hengen Musou training before actively trying to peruse him.

World's End Arc
After all the heroes come gather, around chapter 268-269 of the web novel, Sadina reveals her true background as well as her real relationship with Raphtalia and her parents. Sadina says that Raphtalia and Raphtalia's parents are her reason for living. Apparently Raphtalia's father was a high-born child from a certain hidden village within a secluded country in the east. This particular country is even more exclusive than even the most secluded countries and Raphtalia's parents ran away from it to elope. Sadina cautions Naofumi about the country saying that he should be cautious about them for they might send a priestess or unique ability user like herself to come for his or more importantly Raphtalia's life if he if he impregnates Raphtalia or learns too much about that country's internal affairs.

Heroes

 * Iwatani Naofumi: Sadina appreciates Naofumi for saving the children of Raphtalia's village, especially in regards to Raphtalia herself. She attempts to help him, on Raphtalia's request, to keep Atlas out of his bed, which she does vigilently. However, she herself falls for Naofumi after he defeats her in drinking alcohol, and after Raphtalia returns and she's no longer obligated to detain Atlas, she makes a move on him herself. Naofumi considers her a valuable asset, she is very powerful, reliable and experienced, even in regards to the other allies he has around him. At every attempt she makes to flirt with Naofumi however, she is turned down naturally, she's about the only one to call him out for being dense or cowardly with regards to women, at which point he counters by noting Atlas is so forward nobody could not notice it and that he's just pragmatic with the rest because fostering relationships when they're fighting the waves is dangerous for all parties involved.
