Yura is a non-player character in Final Fantasy VI. He is an esper residing in the Esper World, able to use magic naturally. Yura is one of two espers that has a unique field sprite for an esper, but he cannot be obtained as a magicite and so can't be summoned by the player. Yura acts as the spokesperson for the esper race as a whole when dealing with humans.
Like with most espers, Yura's appearance combines humanoid traits with those from mythological beings. He has brown fur with white patterns, green hair and claws on his toes, and appears to have wings.
A similar looking esper guards the gate to the Esper World during a flashback, but it is unknown if these two characters are supposed to be the same. This character doesn't have a name and gets captured by Gestahl's forces when they first arrive in the esper world.
Yura is angry at humans and wants vengeance for the empire's foray into the magical realm, but when the espers' attack gets out of hand, Yuna feels guilty when he realizes innocents got caught up in the raid. During a treaty negotiation, Yura apologizes on the espers' behalf and says they are in no position to ask for forgiveness to demonstrate his sincerity for peace.
Yura and the other young espers wanted to do something for their friends who'd been turned to magicite. They gathered at the gate when Terra comes to plea to the espers for help in defeating the Gestahlian Empire on the other side of the gate. When the gate opens, the moment the young espers step outside of the esper world they lose control of their powers, go berserk, and attack Kefka Palazzo, who was sent to ambush Terra and her group in front of the gate. The espers attack Vector, the imperial capital. As they are trying to leave, they end up attacking the Blackjack.
Yura leads the espers to the Espers' Gathering Place where he is found by Terra, and senses that she has similar abilities to his own. She convinces the espers that the empire is willing to talk peace, and Yura represents the espers in negotiations with General Leo in the nearby village of Thamasa. The peace agreement is a trap set by Kefka and Gestahl to acquire more magicite. Kefka invades Thamasa and crystallizes Yura and the rest of the espers into magicite.
