Skills:
* Affinity to Weapons - Having a knight bloodline, this enables her to to wield any weapons at ease especially Swords. Regardless of the size and complexity of the weapon, she can still maintain her posture and use it towards great lengths.
*Copy - cat : This skill is similar to Punn's skill in the Gifted Thai series. Erin can copy any skill by observing how it is done and executed. For those skills especially the ones done by Sacred Gear and Magic users, she needs to have direct contact with the user either by touching their arm or any form of contact. This ability is made possible due to her being a half deity which involves having great intellect. The downside is that the copied skill can only be maintaned for a limited time and frequent use of the skill can lead to fatigue and extreme headaches to Erin.
* Lightning Ace - With training, she can command the sky for thunders and lightning to appear as well as creating thunderbolts herself. When out of mana or energy, she can seek for recharge in lightning by using the element as a source of energy. Of course, she needs to have at least minimal energy to create and summon lightning.
*Hidden Aura - Erin's aura is undetectable and she would always appear human regardless if she was transformed or not. This was a gift granted by Zeus.
* Animal Shifter: The gift given by Artemis which enables Erin to shape shift into any predatory animals of the wild as well as domestic animals.
*Sweet Lullaby: Being the daughter of Apollo who has a natural talent with music, Erin has the ability to play musical instruments. The tune produced from her instrument can make the listeners lose their focus or fall asleep. Moreover, Erin's singing voice alone can cause others to be in a trance or hypnotic state.
*Weaponized Arm : This was the gift given by Ares. The weaponized arm materializes like a Sacred gear. Kind of similar in Full Metal Alchemist where Erin's arm would transform into a mecha state which can be used as a weapon. Moreover, she can change the tip to any suitable weapon while maintaing the mecha state of the arm. So its kind of like the arm portion is metal while the base or the hands part is transformed into a weapon (can be a captain's hook, razor blades, Rope, Laser shooter, or Machine gun.)
*Natural Speed: Having a knight lineage and being a former Messenger of Zeus grants Erin the speed which can rival the Knight Speed granted to those devils having those ranks in a peerage.
* Geass: Similar to Lelouch's Geass in Code Geass, Erin has the Absolute Obedience power which can command anyone to follow her orders (except surviving when death is near and other impossible tasks) when there is direct eye contact. However, unlike Lelouch's geass, Erin's A.O is enhanced where she can also command Non-humans like the animals and near-by elements. Moreover, the range of her power is also increased so she can still command her Geass as long as the target is in her eyesight range. Erin can cancel the effect of her Geass by the special charms and ofudas she made.
*Fast Healing Powers = Erin's wounds will heal faster than a normal human. This was the gift given by the other deities in line with her Increased strength and endurance.
Weapons:
*Thunder Shield: The unbreakable shield of Erin which was given by Zeus. The shield also requires Specific User Identification so only Erin can use the shield and in some cases, her family members and direct descendants of her household.
- P.S. I do not own any of the Images used here 😅
* Golden Wings: Erin's wings granted by Zeus to perform her messenger duties. The wings is Golden-like in color with silver streaks outlining the shape. It is designed for long flights which enables Erin to fly for hours without fatigue. When transformed as a devil to Rias' peerage, Erin has the choice to use the Devil wings or her original wings. However, she chose the Devil wings at first to keep her identity a secret and to not arouse any suspicions. In the later chaps, she freely preferred her Golden wings to which Erin described as more liberating and refreshing to use.
* Just choose which Wing you prefer and just imagine the wings having a silver streak in its outline*
*Familiars : They are shown in the later chaps. Erin's familiars are portrayed by 2 of the triplets of the Asahina brothers in Brother's Conflict. They are Underworld wolves which coincidentally serve Hades and because of some unfortunate event the two are mindlessly wandering around the Familiar forest; being hostile and agressive to any individuals who dared approach them. They posed a problem to Zatouji but thanks to Erin, they were finally captured and tamed.
The wolves can transform into their human forms. (shown below in the pic.) They can control the elements of Fire and Ice.
* On the left side is Azusa. He controls the element of Ice and on the right side is Tsubaki who controls the element of Fire.
* These are their Wolf Forms. Just ignore the one in the middle.*
