Biran Ronso is a non-player character in Final Fantasy X. He is a Ronso, born on Mt. Gagazet.
Biran is a powerful Ronso warrior who respects those with strength to match his own. His victory over Kimahri in a battle left tension between the two, and Biran has behaved antagonistically toward Kimahri thereafter, deriding him for being hornless by breaking Kimahri's horn. Biran is a proud Ronso and is willing to show respect to those whom have earned it in some way, thus leading him to praise the summoner Yuna and eventually even Kimahri.
