Aequali de Roma

Aequali de Roma is a pureblood prince of Evangale and younger brother to Johann de Roma.

Appearance
Aequali has blue eyes and yellow hair. He is often seen wearing blue robes.

Personality
Aequali comes across as very kind and empathetic, and is willing to be generous and helpful to others. He frequently acts as the voice of empathy, desiring more peaceful outcomes, which led him to be labeled as an idealist with unattainable goals. However, he also harbors a darker nature, and his kindness to Deor appears to be a facade. He is willing to kill his own family if they get in the way of Deor's growth, and also harbors a desire to "consume" Deor. He only ever reveals this side of him to people he is about to kill or to witnesses.

It is unknown if Aequali's kind and empathetic personality is genuine or fake. While he tries to hide his darker nature from witnesses, he does not appear to have a malicious goal in mind. He seems to genuinely despise the corrupt, duplicitous tactics his family has used for political gain, and has only eliminated those who stood in the way of that. He also believes his method of killing is more humane since it is painless compared to the usual methods used by the royal guard.

History
Not much is known about Aequali's past. Before Vincent Evangale allowed any of his kin to claim the crown, Aequali wanted to poison Camille Fluenti, Deor's mother. However, he has changed since then.

Plot
Aequali appears when summoned by King Evangale, and later offers a strong hand of support to Deor.

A few days later, Aequali helps fight and arrest assassins sent after Deor. At the Royal Banquet, he converses with his brother Johann and adopted sister Solaris when Lady Fluenti suddenly collapses. He runs to heal her, extracting poison from her body. While the castle occupants are busy investigating, Aequali slips away to confront the perpetrator: Johann. He and Johann argue when Aequalii is suddenly stunned by a demon. This proves useless as Aequali overpowers the demon and kills Johann.

Aequali meets up with his uncle Frey Evangale as they subdue an escaped prisoner, who turns out to be one of the assassins he arrested. Aequali reveals that he is aware of Deor being a demon, terrifying Frey. King Evangale suddenly shows up, destroying a demon in the process. The king has one assassin arrested and attempts to kill Sasha, but Aequali offers to do it instead. Aequali, after ensuring no one is watching, uses his water magius, to presumably disguise his hidden demon abilities, to consume Sasha. As he does this, he contemplates how the other guards would callously bury her alive, while Aequali's method is painless and more humane.

Aequali then confronts Frey as the uncle considers how to best get rid of Deor. Aequali reveals he is the one who killed Johann and kills Frey for his part in the conspiracy as well. He then confronts Solaris, who had witnessed the scene. He reveals Deor's origins and expresses his desire for Solaris to become the ruler to a shocked Solaris. While he is able to calm her down, he is forced to knock her unconscious when she protests leaving Frey to die. Aequali begins consuming Frey's body to hide the evidence while wondering how Deor will taste.

Magius
Aequali is shown to have a powerful water magius, which he uses for different purposes. He is able to use it to extract poisons via the esophagus, as shown in Episode 16 when he saves Camille Fluenti with this method. He also uses it to disguise his demonic powers.

After killing Johann, Aequali took his lightning magius crystal, granting Aequali the ability to use it.

It is unknown how Aequali is able to possess a water magius, as demons are not born with one.

Demonic Powers
Unknown to everyone else, Aequali has demonic powers. It is unknown how and when he acquired this. It is unlikely that Aequali himself is a demon as he also possesses a magius. He has used this power to consume his victims. This ability also gives him the ability to regenerate any damage.
