Eiza

Eiza is a gray and white cat that had to leave his family at a young age, whilst being chased by Iris, his nemesis. Later on, he was found hiding and adopted by Cosmo. Eiza is mute, meaning that he never speaks, and his vocal chords have stopped functioning because of the lack of use. Eiza is anxiety embodied in a cat, and he doesn't like communicating with people because it's confusing and strange to him. Despite this fact, he has several friends, and he likes all of them.

Trivia

 * Despite him being a cat, Eiza doesn't catch and eat birds, rats, or fish, unless he dislikes them for emotional reasons.
 * Eiza's last spear was given to him by his parents before they both had been killed, but that had gotten lost in a battle. He now has a new spear, given to him by his best friend, Zerde, which looks similar to a crow.
 * Eiza likes Zerde, despite knowing that he'll never be with him, or be able to ask.
 * Eiza's only spoken twice in his entire life, both times being during emotional struggles and before his vocal chords wore out.
