|Illerina von Einzbern|
|Also known as:||"Steel Collusus Lily"|
|Character type:||Dorm Head, Master|
Dorm head of the Einzbern Homunculi, and their most powerful member in OLYMPUS. Arguably one of the most powerful homunculi in existence. Pure-battle-type created to wage full-scale war while being against a small-sized army. Has almost no social functions, but makes it up by having body that is harder than tungsten steel and weighs few tons. Has both slain Servants single-handedly and was responsible for the fall of the Poseidon Ward. Extremely dangerous when in battle-mode, and the chance of collateral damage is high.
It is said that, among all the Dorm Heads, Illerina possesses the highest defensive capabilities amoung the dorm heads.
