Angelus Sicila

Sicila aka Angelus of Joyness.

Not pure angelus but human get turned into angelus.

On the first encounter she was an enemy that Leandro, Meos, and Daosmon fought against.

After her first encounter with Dania, Sicila didn't expect that the Archetype Of Protection is actually a friendly small girl.

So she gave her address card to Dania and expecting her to come to her hidden bar to see if Archetype of Protection is that dangerous based from what Matra said.

But to her surprise that Dania come only to ask about how the angelus and the false messiah been planning instead making surprise attack.
Dania also promise her that she will find a way to return her back to human and cut the angelus mind control to prevent her from turning into sea monster if she ever try to betray/disobey the angelus.

On that day, Sicila secretly work under Dania as her undercover agent to spy on the angelus and the false messiah.
