Keyaru

Keyaru (ケヤル), also known as Keyaruga (ケヤルガ), is the main protagonist of Redo of Healer. On his 15th birthday, he was chosen as one of the Heroes, the Hero of Healing.

After years of torture at the hands of his "allies", he manages to break free and get the Philosopher's Stone. He then uses the item to go back four years time to exact revenge against the people who tortured him. After killing the former king, Keyaru became the new king of the Jioral kingdom, to transform it into a genuinely peaceful kingdom.

Appearance
Keyaru is a young boy of medium height with brown hair and red eyes. Initially, he is dressed in simple clothes he used in the village, then after the start of his revenge he uses a set of armor he stole from the Captain of the Guards. When he uses his Heal skill, his eyes turn green. His new appearance as Keyaruga is just an older version of himself. In his "Keara" disguise, he gives off a more feminine appearance - a buxom maiden with waist-long brown hair with a red ribbon on the back of the head, except leaving the male genital intact.

Pre-Betrayal
Initially, Keyaru was a very kind and gentle boy with dreams. When he discovered that he was one of the Heroes who would save the world, he was very excited but he was afraid to use his power when he found out that by healing people, he absorbed their memories and pain.

Post-Betrayal
After being betrayed, imprisoned, drugged, tortured, beaten and raped by several people who wanted to break their level limits for a long period of time, Keyaru's kind personality changed completely to that of a man vindictive, cruel, brutal, unstable, psychopathic, relentless, bloody and sadistic. Because his naive personality was what allowed him to be exploited, Keyaru replaced his old personality with that of a manipulative and cunning misanthrope.

He completely discarded almost all of his old, kind and generous personality in order to become a sadistic, violent and cold-blooded killer so that he could have his revenge.

Revenge is Keyaru's primary concern, although at least once he has mentioned the possibility of "living happily" once he has taken vengeance on his abusers. When Setsuna asked him why he seeks revenge so much, Keyaru explains that the idea that those who tortured him can just live their lives without suffering the consequences makes you want to vomit. Another example of his sadistic personality is when Keyaru thoroughly takes pleasure upon taking vengeance, as seen by his happy laughter after having raped Flare and erasing her memories. The only exception shown so far is the Knight Captain as even after Keyaru turned him into a woman and make them raped by his soldiers as revenge for having raped and tired Anna's death, he displays nor happiness nor satisfaction during it and afterwards, presumably because the Knight Captain's actions resulted in the death of many of Keyaru's loved ones. When his first love, Anna and all the villagers in her village were killed by Renard, Keyaru becomes completely cold and suffers extreme levels of despair and anguish after losing his last sheds of humanity by becoming the sole survivor of his now deserted village.

Keyaru also explains to Setsuna that just seeing the suffering of those who made him suffer, Keyaru feels a stimulating feeling and fills his heart with pleasure and satisfaction. Keyaru also laughed madly in glee, delight and satisfaction after having Blade raped and eaten alive by three angry thugs under the influence of an aphrodisiac.

One of Keyaru's redeeming factors is that he has no desire to harm those who have done him no harm, and in fact makes it a personal rule not to drag them into his revenge; this applies even to people who are otherwise cruel like Princess Norn (until he discovers that she had a hand in executing the captured members of his village). Keyaru also has some sympathy for people who strive for justified revenge the same way he does, and will do his best to help grant them their desire with the condition that they also help him with his.

It is quite difficult to interpret how he really feels about the girls in his party,as he refers to them only as yours ´toys´,in his inner thoughts,this implies that he does not really love them and only sees them as simple tools.

However,apart from that and some relatively minor things,like making Freia carry his luggage as a form of revenge for having used him as a pack mule,he treats them only with kindness,in total contrast to his own treatment at the hands of the Flare's party.

Keyaru has also shown himself to be genuinely enraged whenever any of them are injured,this could be seen when Kureha knocked out Freia,before that,when two bandits tried to kidnap Freia,Keyaru ordered them not to touch her,being even willing to kill them. But it is not clear that it means that he is more protective of them than he can realize himself,or if he is just simply possessive.

Keyaru has also confessed once that during his travels with his party,even if only sometimes,his thirst for revenge vanishes,but he disregards this when he remembers that she still has people to get revenge on. But this may be an unconscious way for him to refuse to acknowledge that he is starting to care about other people,out of fear of losing them too.

Previous Timeline
As he was one of the chosen heroes, Flare Arlgrande Jioral took Keyaru from Alban Village to Jioral Kingdom, where he identified himself as the Healing Hero. Unfortunately for Keyaru, prejudice against the healer class resulted in Flare, the Heroes and Jioral Kingdom abusing and torturing Keyaru to the point where he was addicted to a healing drug Flare fed him to keep him in line. While Traveling with Flare, Blade, and Bullet, he was often sexually and physically abused by all three. Developing an immense hatred towards them, he eventually develops a resistance to the drug and is able to maintain his sanity. However, as he was aware that he would be unable to take any of the heros in a fight, he kept quite and pretended to still be dependent on the drug. At some point the group met up with Norn, with her discerning that he wasn't broken. Intrigued by him, she decided not to tell the others on the condition the Keyaru entertains her.

When the heroes are incapacitated by the current Demon King, Keyaru is able to defeat and reveals him to be a silver-haired woman. Using the Philosopher's Stone he obtained from her, Keyaru declares vengeance on Flare before reversing time by four years.

Current Timeline
After waking up in his village, Keyaru goes into the woods and obtains the ability to read the statuses of others from the spirit of the stars. This process takes 5 days. Over the next 7 days, he eats numerous toxic mushrooms every day to develop his poison resistance. Eventually, Flare comes to his village and Keyaru reveals himself as the Healing Hero. She then takes him to the royal capital of the Jioral Kingdom.

After arriving at the capital, Keyaru notes that he is too weak to challenge any of the soldiers. That night, a maid seduces and has sex with him in his room to increase her level cap so he takes the opportunity to steal some of her experience. Over the next week, he would have sex with all of the maids in the castle.

When he is finally called to restore Kureha Clyret's arm, Keyaru takes some of her experience and pretends to faint to get a look at Flare's reaction. Upon seeing that she gave up on him the first time he used his Heal ability, Keyaru takes delight in how he won't feel guilty taking revenge. Later, Keyaru is given a cup of drugged tea by Flare and after he drinks it, he falls unconscious. He later wakes up chained in a prison cell. In confinement, Keyaru is raped by soldiers who want to increase their level cap nearly every day while the drug is repeatedly used on him. He keeps enough sense to steal experience from soldiers raping him, and after several weeks he acquires drug resistance to prevent him from succumbing to Flare's drug anymore.

Overhearing from the guards that the king is away, Keyaru escapes his prison cell after one month of captivity as well as 2 weeks of having his consciousness back. After evading the guards under the guise of a knight, he exacts vengeance on the knight captain by besting him in combat and transforming his appearance to look like Keyaru's, before transforming himself to look like the captain. As the knight captain, he turns "Keyaru" in and asked to speak to Flare in her chamber. Utilizing his disguise, Keyaru is able to isolate himself, Flare, and her attendants in Flare's chambers. Killing her attendants with a technique stolen from Kureha, he then proceeds to torture Flare, breaking each of her fingers until she can no longer hold back her screams. He then makes her submit to rape by making her choose between his manhood and being burned by a metal rod. To complete his revenge, he transforms her appearance to suit his taste and erases her memories. He transforms one of the dead attendant's bodies to look like Flare's before taking her and leaving the castle. After arriving at an inn with Flare, he changes his appearance and adopts the name Keyaruga. He then convinces the amnesiac Flare that she is his slave and lover, Freia, before the two have passionate sex.

Keyaruga and Freia make their way to a village ravaged by a plague. Realizing that the illness is originating from the water, Keyaruga creates an antidote which he sells to a merchant. He then proceeds to use the money to buy an ice wolf slave, Setsuna, who agrees to serve him in exchange for his help to get revenge on the people who attacked her village. Keyaruga has sex with Setsuna to increase her level cap on and the next night, the two of them, along with Freia, stop the attack of the Jioral soldiers on her village. Keyaru kills multiple soldiers with techniques stolen from Kureha. Following the battle, Keyaruga and Setsuna discover the source of the village's illness, a monster corpse thrown in the water as retaliation for the actions of the Jioral soldiers. He gives Setsuna the choice of what to do, and she chooses to heal the humans, as most of them are innocent and she seeks to kill the guilty ones herself.

The next day Keyaruga's group is confronted by Kureha, who heard that someone used her family's swordsman ship to kill soldiers. Keyaruga manages to hold her off with the help of an aphrodisiac, but she is still able to cut his arm off. Catching her off guard by healing his arm, he proceeds to show her the memories of the ice wolf tribe as the soldiers attacked them, and the shock of the revelations cause her to fall unconscious. When she wakes up, Keyaruga and Freia, as Keyaru and Flare, both explain that they see the evil in the Jioral Kingdom, claiming that they faked Flare's death and are working to save the kingdom. Kureha is initially shocked by the revelation but comes to accept their reasoning. Under the effect of another aphrodisiac set up by Keyaru, the two proceed to have sex.

Keyaru soon finds out that nearly everyone in his village was rounded up for execution as a way to draw him out. Upon learning that Anna died at the hands of the knight captain, Keyaru exacted his revenge on the captain by turning him into a woman and brainwashing the captain's men to rape him to death, before setting the house they are in on fire. He goes to the coliseum to try and save the rest of the villagers, but learns they were poisoned to ensure that wouldn't be possible. Despite this, he is able to turn the spectators against the authorities by having Freia adopt Flare's appearance and inform them of the kingdom's atrocities.

Powers & Abilities
Heal: By healing things and concepts, Keyaru performs various abilities from the Healer Class: Jade Eyes: Also known as "The Eyes of the Spirits" and "The eyes that can see through all things in the universe", is a pair of powerful magic eyes that Keyaru obtained by making a pact with the spirit of the stars. It allows him to perceive the mana floating in the atmosphere, the leylines, information about the target's true name and their stats, such as Magical defense, Physical defense, Level, Mana, Health, Class, Abilities, Passives, and Speed. After the events in Volume 4 of the light novel, one of the jade eyes gets turned into a different magic eye.
 * Recovery: By manipulating time and matter, Keyaru can return things to their original states and heal deep injuries from himself or others. Initially, using it to heal someone would cause him great pain, but later on he learns how to use this skill without showing any signs of pain at all.
 * Imitation: Every time Keyaru heals someone, he gains the fighting skills and experience from that person. He already used this skill many times before, retaining all the knowledge from different fighters, soldiers and mages.
 * Predator: Can either absorb or copy some of the levels of a person, allowing Keyaru to level up. The same ability can also be used to absorb all the mana from someone, or just a portion if he wants. If the target is a mage or fully dependent on mana, that person gets incapacitated and weakened.
 * Corruption: Destroys the target from inside by corrupting them. Keyaru usually refers to this ability as a One-Hit KO skill.
 * Upgrade: Ability that allows Keyaru to modify things by "upgrading" them to a desired state.
 * Superhuman Augmentation: By upgrading himself, he can change his stat spread by enhancing some stats (such as strength, speed, magical defense, physical defense, and magical attack) at the cost of reducing others. He cannot, however, change his stat total.
 * Transmutation: This allows him to change an individual's appearance, physical stats and mind.
 * Memory Erasure: While touching someone's head, Keyaru can change the memories of an individual and can also erase them at will. He can also force the target to experience memories, as shown with Kureha Clyret.
 * Shapeshift: By using Upgrade on himself, Keyaru can change his appearance.
 * Rewrite: Keyaru can use Upgrade on enchanted/magical objects, changing their functions.

Eye of Precognition: Also known as the "The Eye of the Divine Bird", is a powerful magic eye that Keyaru obtained as a reward for passing the divine bird Caladorius' trial. It allows him to see few seconds into the future, enabling him to evade and counter enemy attacks.

Drug Resistance: Thanks to having trained his body extensively by consuming massive amounts of toxic mushrooms and having subsequently shaken off the effect of Flare's drug, Keyaru is immune or incredibly resistant to the effect of most poisons and drugs. This is what allows him to use his alchemical grenades to great effect, as the fumes that are debilitating to others have absolutely no effect on Keyaru.

Level Cap Break: Being one of the heroes allows him to level up as much as he wants without having a level limit, and as a male hero, he can also increase the level cap of others. Keyaru does the latter for his party members by having sex with them.

Increased EXP Gain: Being one of the heroes allows him and his party members to gain double the EXP, stacking multiplicatively with the other heroes if they are in the same party.

Intelligence: Keyaru is extremely intelligent and cunning. He is shown to have an impressive knowledge of magical theory, being able to develop many unconventional uses for his own Heal spell, teach Freia how to best use her magic to her advantage, and rig an enchantment to his own benefit. He is skilled at developing strategies and tactics to ensure that any battle he partakes in swings to his advantage as much as possible. This is best illustrated during his assault on the Arena, wherein he not only infiltrates the place several weeks in advance to stealthily tamper with its defenses, but also develops a plan to swing the hearts of Jioral Kingdom's residents in favor of his cause. Keyaru is manipulative and knows exactly which buttons to press to turn a person into a loyal follower, as shown with Setsuna and Eve Reese.

Alchemy: Keyaru is a skilled alchemist due to having copied the skill from Watilda, a master alchemist, while regrowing both of his arms in the Rai Nara room. He is able to magically "transmute" matter into other forms, as seen for example when he turns a lead pipe into a key. He is also a capable creator of airborne poisons, such as an aphrodisiac that makes the target too sexually excited to fight, or a deadly paralytic agent. He keeps them in flasks that he shatters against the ground when needed, letting the deadly vapors spread. He also has needles to inject the poisons directly into a target for added effect.

Holy Sword: Keyaru is a skilled swordsman due to having copied the skill from Kureha Clyret while regrowing her arm in the current timeline. While the skill is not on Kureha's level and Keyaru does not have the ability to defeat her in an honest sword fight, his skill is sufficient enough to defeat nearly anyone else with a sword, especially when he reallocates his stats before a fight.

Elemental Magic: Keyaru copied Flare's ability to cast magic of all elements.

Equipment

 * Divine Armor Georugius: A gauntlet (ring in the manga) Keyaru formed after obtaining Blade's Holy Armament and forming a contract with it. As long as his mana has not been exhausted, Keyaru can use the armor to automatically heal injuries. The armor also allows him to send spells up to a meter away that would otherwise require physical contact; shown when he used the armor to cast Corruption on Hawk Eye from a short distance.

Etymology
His real name Keyaru (ケヤル), fake name Keyaruga (ケヤルガ), and his feminine name he used while disguising as a girl Keara (ケアーラ), are all similar to healing magics from the Final Fantasy video game series (Cure, Curaga and Cura, respectively), as opposed to Flare's name associating with an offensive magic.

Quotes

 * "The weaker Keyaru no longer exists. I have been reborn. My name is Keyaruga. I will redo my life how I want it. I am strongest healer." - Episode 2.
 * I am a pacifist; as long as you don't do harm, I won't come at you first. However, the moment you've become my enemy, there's no forgiveness. Light novel volume 2
