Minerva

Minerva (ミネルヴァ) was the Witch of Wrath. She formally debuted in Arc 4 as a supporting character.

Following her death 400 years ago, Echidna collected her soul and brought it to the Sanctuary along with the other witches. Throughout Arc 4, she and the other witches helped Subaru accept himself and change his views on Return by Death. After the arc, her soul was transferred into a crystal and she is currently travelling with Omega.

Appearance
Minerva was a beautiful young woman who stood at exactly five feet tall. She has been noted to have been in her late teens years and had vivid slightly-slanted sky-blue eyes that were almost transparent. Her long gleaming golden hair was tied into a messy ponytail on the left side of her head that rubbed against her face. A pretty pink and blue love heart pin was also fastened to the left side of her head. She had bountiful breasts and a shapely bottom that lent her a fair deal of sex appeal in the eyes of Natsuki Subaru.

Her primary outfit consisted of an extremely short sleeveless form-fitting one-piece purple dress with a cleavage-displaying cut-out, a translucent sleeveless light purple bodysuit worn under all of her clothes, a pair of thigh-high white boots with purple interior, a pair of long white gloves with purple interior, and a long white sleeveless coat with a cleavage-displaying cut-out that allowed a part of her dress-covered breasts to spill out.

Personality
Minerva doesn't like conflict as she always lamented it while healing people. She also only cares about what's in front of her, stating that she didn't care about what she can't see, such as the side effects of her ability, though she will immediately head off to address it once her current problem is dealt with as long as there are injured people. She is seen being prideful of her work. She often acts very hostile by punching people out of nowhere or scolding them for putting their "lives in danger", however her adorable way of doing so and the notion of helping, makes it impossible for people to get offended by her actions. She often mistakes her sadness for anger and/or wrath, using it as an excuse for crying. Her outbursts of anger are described as being very adorable. She hates the world for making people do despicable things and hurting other living beings. Due to her naive personality, Minerva is said to be extremely easy to fool.

History
In the past, people in the world around Minerva were constantly fighting, causing her to cry. Eventually, she realized that crying wouldn't solve anything and decided to train herself in order to gain enough power to be a deterrent to fighting, though that still didn't change anything. As she fought, she came to understand that she'd been crying out of rage and not sorrow, causing her to start punching people, resulting in their wounds being healed. From that moment on, she traveled the world to heal people wherever she found people in need. Many nations sent troops after her, trying to capture and/or defeat her, but no one was able to successfully catch her.

Minerva also has some kind of history with elves as she cared deeply about Emilia and the other elves.

It is claimed that over 400 years ago, someone used a larger group of elves as collateral damage in on order to get Minerva trapped. The elves were sent as a suicide squad, and in order to save them, Minerva ran to their rescue and fell under the influence of said trap, where she eventually went mad and subsequently died by the hands of the Witch of Envy. Echidna later located and collected her soul, allowing Minerva to manifest in Echidna's castle of dreams, alongside the other Witches of Sin that had perished 400 years ago.

Abilities
Authority of Wrath (憤怒の権能 Fundo no Ken'nō): Minerva is able to use the Authority of Wrath.
 * After absorbing the Wrath Witch Factor during her life, Minerva gained access to the Authority of Wrath. Due to the nature of the power that made Minerva incapable of directly harming another person, the Witch of Wrath was by far the weakest wielder of a Witch Factor among the Witches of Sin and Sin Archbishops.
 * Healing: Minerva's Authority allowed her to heal the wounds of organic lifeforms, although her power was only able to affect physical wounds and not mental wounds. To activate the power, Minerva had to strike (e.g. punching or headbutting) the target with a part of her body. She could also use projectiles to administer her striking aid. Although she was never able to demonstrate it, Minerva's Authority was capably of overcoming the blessing of the grim reaper used by Theresia van Astrea. Her power was able to undo the damage done by Typhon's Authority. On the down side Minerva was unable to deactivate her healing properties, meaning any form of attack she made would heal a person even if she didn't want it to. Even projectiles thrown by her were unable to harm another person. The properties of her power meant she couldn't even kill an insect by stepping on it, meaning she literally couldn't hurt a fly. She was still able to harm others indirectly by causing environmental damage (e.g. using her strength to cause a rockslide to fall on top of enemies) however, the author has stated that as long as it was an action taken by Minerva it would have the same outcome. This ability had the side effect of taking mana from random places in the world causing natural disasters to occur effectively making it so she killed many more people than she saved

Trivia

 * According to the author, Minerva's birthday is July 20.
 * Like the other Witches of Sin (with the exception of Satella), Minerva received her namesake from a celestial body. 93 Minerva is the name of a large asteroid located in the solar system's asteroid belt. Her name, like the celestial body, may also be a reference to Minerva, a Goddess of wisdom and strategic warfare appearing in Roman mythology.
 * With her Authority of Wrath, Minerva would be able to heal the wounds caused by Theresia's Divine Protection of the Reaper.
 * Excluding Satella, Minerva was the most dangerous Witch due to the side effects of her Authority. She was often hunted cause of the sheer level of damage she was indirectly responsible for, but ultimately always managed to escape unscathed.
 * She was physically unable to harm anyone directly, even if she wanted to.
