Riiya

 was a bear +Anima of the Tooa Tribe, and father of Senri.

History
Riiya took Senri with him and some other Kim-un-kur to hunt down Amurui. Senri wandered off and was attacked by Amurui, so Riiya tried to take him to safety while Upas fought off Amurui. Upas was overpowered and injured, so Riiya turned back and killed Amurui using +Anima Metamorphosis, a power he had never displayed before. A piece of Amurui's Anima had infected him, so Riiya passed on his own Anima to Senri before becoming completely enraged and attacking Senri. Riiya was killed by Senri.

Senri
Riiya's son, who he was very close to.

Upas
Riiya's best friend. They were willing to put their lives on the line for each other.
