Ais Wallenstein(Blue (lawful good): being lawful good means you only see the world in black and white in terms of good and evil, common for those with the Avenger Development Ability due to not being able to feel any emotions to help guide their actions in the world completely desensitized to it and only know good and evil by what is told to them, whether they listen to reason or morality at all)

Loki Familia (due to being in the Loki familia, Ais has an increase in her Magic's strength and longevity as well as being partially immune to illusions and mental-based attacks)

Magic

Ariel: wind element enchant magic serving as a powerful offensive weapon and a magical shield, able to deflect projectiles solid or liquid, Despite the strength it gives her, due to it draining her Mana quickly, she often times uses it till she's out of Mana and then exhausted and vulnerable, resulting in her needing to be saved by her Familia thousands of times over, meaning if she isn't able to end a fight quickly, she will destroy herself before her enemy does

Skills

Dragon Slayer A: this skill increases damage done, resistance to damage taken, and immunity to a certain type of enemies or enemies with similar features to them along with a resistance to that said enemies attacks, heavily increases all abilities when fighting

as a dragon slayer manifested from Ais's utter hatred of dragons burned into her soul, Ais is able to do more damage and receive less damage from dragon-type enemies

Berserk B: this makes one lose control of themselves and some of their motor skills in exchange for power and strength in a fight, enhancing all physical abilities that are activated from taking on a certain amount of damage or getting to a certain point of rage, however, they are usually unable to control themselves in this state and can attack allies and also lose the ability to use magic, Strength rises every time the user takes damage or gets more enraged with the ability to also ignore pain and blood loss for a time, based on rank, at I rank, it can increase all physical abilities 3 fold, and at B rank, it can enhance your physical abilities 25 fold

with both Avenger and Berserk, Ais cannot be reasoned with nor communicated with, forcing her Familia to have to use the color on her neck to paralyze and incapacitate her once all enemies have been eliminated or once she starts killing her own Familia members just to keep her under control at that point

Swordsman A: increases one's damage, cutting, and precision with a sword or bladed weapon such as a knife or great sword, it also makes their swordsmanship improve with much faster and reactive strikes as well to eliminate most enemies quickly or battle for long periods without weakening sword strikes

combined with her sword training, Ais is one of the best with a blade, however, she has the weakness of a one-trick pony as she is only skilled in sword fighting and doesn't know how to fight with her bare hand nor other weapons

Iron Skin E: increases durability and dexterity to make one able to tank a hit head-on with little damage, how much damage is taken depends on level and rank, it also includes your organs, muscles, and bones, so internal attacks don't affect the person as hard either

due to her losing control of herself far to often, this skill is useful in the fact that is it able to help Ais be more likely to survive an attack when hit

Acrobat D: this increases the acrobatic ability of the user with incredible nimbleness, body movement, flips, and jumps, and also an increase in the user's climbing and maneuvering in tight or limited-spaced areas

with Ais's sleek body and fighting style, she is able to use this to the utmost degree in battle, though, she often times doesn't dodge attacks to get a strike in on an enemy

Mana Trigger C: this is a burst of Mana that drains a large portion of Mana for a powerful attack, this is costly as the amount of Mana used at once can also damage the user if they are not careful, though it's liked by powerful adventurer's in vanguard as it helps them in a pinch

for Ais, Mana Trigger in combination with Ariel at C rank increases her power to be 5 times more powerful, but also drains her Mana 5 times faster as well, meaning if she can't end a fight quickly, she will suffer mind down and need to be saved by her Familia

Blessed ability

Blessing of Inigo Montoya: (for obvious reasons) with the blessing of Inigo Montoya, Ais has a form of Battle Continuation and the ability to completely phase out pain and mental impairments such as fear or doubt when faced with anything related to her seeking revenge, as well as lose compassion, mercy, and self-restraint/control as well

(if Shakespeare can have an influence in official Danmachi Cannon, then I'm adding "The Princess Bride" in this as well to help my case)

Curse: Hated immortality

a curse that was created by Ais's hatred of the beast that killed her family, Ais will go into a comatose state where her body will show no signs of life for 50 years in a coffin sealed into a cave, and will regress into the age in which the curse was placed in (5 years old), and only when her undying hatred of the One Eyed Black Dragon is gone will she be able to properly die

because of the curse, Ais has lived her live in history as more of a natural disaster more than anything, doing anything to get stronger, only stopping upon being placed in the Loki Familia, where her murderous rampage and killing off everything in her path to get stronger is... contained at best and is under constant control, however, each time she dies, all the progress she made will also disappear as well (a level reset), also, she lost her chastity WAY before in her first life, even if it does regenerate upon her death, she doesn't keep it long due to her not caring in the slightest about chastity since it doesn't affect her revenge, especially since she is infertile

Authors notes

a side effect from having Avenger also affects the Skills and Development Abilities Ais can get, aside from skills that provide resistance, she cannot have a skill that gives near complete immunity or healing, so she can't have Battle Continuation or Regeneration, or skills that have reviving abilities such as Restoration since her body isn't allowed to heal, only break till Ais or he enemy dies first, while Avenger can apply a form of each one, it's half backed at best, it also made giving her Skills and Development Abilities thing's tricky since she

I figure making Ais the way she was, her defense and attack would be high, especially with her being more of a hand grenade the Familia can't control but can use if they keep her far enough in the front

I decided to give my version of how Ais lived as long as she did and make it more tragic as well, having her hatred literally be the only thing keeping her alive, she literally lives and died by her hatred, as an embodiment of "While seeking revenge, dig two graves - one for yourself" Douglas Horton

for those who don't know, look up the name with the princess bride for a character I looked up on dedicating their entire life to revenge, as well as SCP 076-2 for the immortality function as well since both seem appropriate for Ais in this instance as well as showing she's just as bad a monster if not worse than the very monster she wishes to slay
