Yarne is incredibly cowardly, timid and excessively worried, since his "Last Taguel" status makes him scared that if he dies, the Taguel will become extinct. In addition, he constantly fears that if his father cheats on Panne, he'll cease to exist, which he is also afraid of. Yarne also is afraid of anything, ranging from the enemy to insignificant things. He often tries to find a safe place to be in, such as being allied behind strong people or an area with no hazards at all. Like his mother, Panne, Yarne is able to detect friend or foe from a distance, as shown in a support with the female Avatar.
