"Do you not see reality for what it is? You are weak and pathetic in battle! Do you not lament your inability?!"
—Arche-Lucia talking to Fuuka

Arche-Lucia (アルゲー・ルキア, Arugē-Rukia) is the third boss of Persona 3 Em and the Arche form of Fuuka Yamagishi's initial Persona Lucia. It is encountered on the 60th floor of Oneiros.



Arche-Rukia appears in battle without a Persona User, and takes the form of Lucia.


The Arche persona symbolizes a part of a person that they do not fully understand and that is difficult for them to accept, similar to the function of shadows in Persona 4. What that entails for Fuuka is unknown, however the pre-battle dialogue options are "I don’t understand..." and "I won’t believe it!".

Though Lucia does not have any listed affinities or combat stats, Arche-Lucia blocks all Magic attacks and can only be damaged by Physical or Almighty attacks.
