Eijiro is a tall and heavily-built Felinoid with light-brown fur on his face and white fur around his mouth, sharp eyes, and he wears Guardian Armor with the symbol of a pink cat's pawprint on the chest.
He wields two shields with blades attached to them, cat face images on the shields themselves.
Eijiro appears to be a no-nonsense sort and takes his job very seriously, as he forcefully pushed an Adventurer down simply for getting too close to his charge Malves. He is protective of his charge, constantly on guard and prepared to fight.
In fact, he appeared to want the adventurers of Akiba to attack or otherwise insult Malves to give him an excuse to attack them in apparent self-defense and further damage the Round Table's reputation.
