Demonic Abilities were weird by Anfang's standards.
Most of them were so volatile that they defied the norms. Some Sin Series Abilities could even upset the balance of power in favor of their users.
This was usually the case because the demonic Abilities took users' emotions, wills, and intents into account. Since the emotions were unpredictable, the same unpredictability would manifest in the respective demonic Abilities as well.
Reva Rain's Ability allowed her to cast a wide debuff AoE on her opponents drenched in Reverse Rain. It also allowed her to heal from severe injuries. The rate of the healing was dependent upon the emotions of pain and suffering the opponents felt while being affected by the AoE Ability.
Reva could also heal her allies using Reverse Rain. It was she would have to cause equal amounts of suffering, if it could be quantified, that is, to make up for healing multiple rankers from her team.
The Reverse Rain was a rare and potent Ability. Reva had become a title holder in Edinburgh because of her signature power. She was named Paladin of Pain because of the ill effects her Ability had on her opponents.
Reva would first target her opponents with the Rain of Pestilence followed by other forms of rain. In the end, she would let them get drenched in the Rain of Death, allowing them to find a cure for their suffering in death.
Most of Reva's opponents died with expressions of pain and suffering painted on their faces. Almost nobody could manage to keep their consciousness separated from the amount of suffering they were feeling at the time after all.
Reva Rain activated her Ability to its full potential when she saw Eren's conviction. It was as if he knew about her Ability all along. As if he knew what he was signing up for by confronting the Paladin of Pain head-on.
Eren's main receptors were overloaded when he was affected by Reverse Rain. It was just like getting drenched in illusory rainwater except there was no water involved in the equation. Instead of water, it was as if ethereal emotions had been liquidated and turned into droplets of rain. These illusory droplets would then affect those who came into contact with them.
Eren had already experienced Reva Rain's Ability multiple times on his past timeline. He had also suffered from her hand so that she could practice various facets of her Ability on live test subjects.
So he had already come prepared to get drenched in the Reverse Rain. He managed not to give in to psychological and physical symptoms caused by her Ability. The butcher charged his daggers with compound elemental fusion before attacking the Paladin of Pain.
Eren cut Reva's abdomen vertically before inserting his hand into the newly opened cavity. He grabbed onto something before yanking it out of Reva's body. By this time, he had reached the threshold of handling pain.
Eren couldn't afford to get drenched by the Reverse Rain for longer. So he used his movement spell to step out of her demonic Ability zone.
Reva Rain's consciousness stepped out of the illusory world Eren's Ability had pulled her into. The pain she was subjected to was enough for her to do that. When she did, she screamed.
"Aaaaaaaargh!"
The Paladin of Pain couldn't even use her Ability to heal herself. That's because the Reverse Rain didn't invoke the required emotions and sufferings in Eren. All she could do was try to close the wound with her hands in vain, turning them bloody and making the situation deteriorate.
"Heh! Organ harvesting is no fun when it's done to you, right?"
Eren smiled gracefully at Reva before showing her what was in his left hand. It was a meaty organ that was dark red. Since it was a fresh organ from an Expert ranker, it radiated exceptional amounts of vitality and life force.
Reva Rain lost a large chunk of her liver in the butcher's first attack.
The Paladin of Pain had never felt so much pain in her entire life as she did at this point. However, there was another emotion trying to take over the psyche which was almost equally strong– surprise.
"How… aaaaargh… how do you know about organ harvesting?"
Reva looked at Eren with a fearful expression on her face. It was as if she stood naked in front of the butcher. It was as if all her secrets were laid bare before him.
Eren entered the Expert rank recently. And he overpowered a demonic ranker like her who was close to breaking into the Master rank. It spoke volumes about the butcher's ranker potential.
Reva Rain's liver disappeared from Eren's hands. In its place appeared the katar that the butcher had used to hurt Reva. The butcher's emerald green eyes shone with determination as he asked his rhetorical question to his opponent.
"Ready for round 2? Which organ should I harvest this time?
Eyes? Lungs? Pancreas?
So many snacks… so little time.
*Sigh. The tragedy of being good at one's craft, I guess."
The butcher sighed as he looked at Reva's body as if it was a living and breathing organ dispensing machine. Reva felt threatened by his gaze. Still, she mustered courage and clenched her fists before replying to him.
"You… you will not be spared, Eren Idril. Do you hear me?
I and… aaargh… I and Demonmir will ruin you.
Back off… back the fuck off. NOW!"
Eren chuckled at Reva's empty threats. He looked at her intently before saying the same thing she was used to saying in a mocking tone.
"Tch. Tch. Tch. Don't you know, Paladin of Pain? Those who inflict pain must have the courage to bear it as well.
Are you telling me you don't practice what you preach? We can't sully your image like that? Otherwise, people will call you a hypocrite.
Let me protect your image. Let me stifle the flames of infamy trying to get to you.
Ready or not… here I come."
