Kosyu is a non-player character from Final Fantasy XIV. He is a member of the Nagxian Resistance.
When the invasion of Nagxia reached Bunlai, Kosyu was only eight years old when most of his kin were killed, and together with the other survivors, he fled the village and became a refugee. As the imperials advanced, they were forced farther and farther southward, and they were met with many hardships on their journey. Kosyu's younger sister was claimed by sickness, and he had no choice but to bury her himself. He swore on her grave that he would never shed another tear, and from that day forth, devoted himself to the resistance.
One year before Nagxia finally lost its war with the Garlean Empire. Kosyu was patrolling the jungle when he encountered a mother and daughter, emaciated from hunger and exhaustion. The woman used her dying breaths to speak of the tragedy that had befallen the village of Dagluk. Traumatized by the passing of her mother and the barbaric scenes she had witnessed, the young girl could not utter a single word. Her name was Atori, though it would be some time before Kosyu would learn this. She bore a strange resemblance to his deceased sister, and he soon found himself caring for her as though she were his own flesh and blood.
Eventually, the pair grew to become two of the Nagxia resistance's most valued warriors, and they fought bravely in the battle for Castrum Viride, their achievements earning the acclaim of their comrades. When the Eastern alliance was asked to send reinforcements to aid the Bozjan Resistance, Kosyu and Atori were quick to volunteer, and their requests were immediately accepted.
Raised in a remote village in northern Nagxia, Kosyu is one of the few Roegadyn native to the region. His true name is difficult to pronounce for those not of his clan, so his comrades in the resistance have given him the nickname “Kosyu,” which means “tiger whiskers” in the more commonly used local dialect.
His thick accent paired with his habit of mumbling means he is often misunderstood, and as a result, he does not make friends easily. However, his skill with an axe is without question, and the decision to send him to the Bozjan front line was met with unanimous approval.
Kosyu is an eastern roegadyn with dark skin and white hair, he has a small bushy beard and wears a ao dai dress dyed soot black. he wears white puffy pants underneath along with spiked armored greaves. In battle he wields the axe kintoki.
Kosyu is a hardened soldier, who cares for his family and friends, he is driven to fight the imperials and drive them from overtaken lands. Often quick to volunteer in skirmishes against the empire.
Kosyu appears as an allied npc during the skirmishes Of Beasts and Braggadocio, Sever the Strings, and A Relic Unleashed in Zadnor. He uses the abilities Tiger's Claw, Tiger's Eye, Voracious Swing, and Jungle tempest which is a large circular AoE with colorful flowers.
