Red: I've been really into this anime for a while now, and I have to say, I'm a bit disappointed by the lack of crossover fanfics despite how popular One Punch Man is. As a result, I decided to write my own story. Hopefully you guys will like it.
I really haven't decided on the pairings yet. Maybe another Genos/Kagome, but that's already been done a few times. Maybe Saitama/Kagome since I would love to see Saitama have a nice lady friend by his side who he could care about. Or maybe, for the grand slam, it'll be a lovely love triangle between Saitama/Kagome/Genos. I think this would be cute because both of the guys wouldn't care they would have to share with each other. xD
Anyway, I'll just see what people think about this. Tell me your opinion in the reviews.
Edit to authors note (7/7/17): This story is currently rated T but is subject to change in the future.
Summary: She thought the only way to save everyone from the Jewel was to not make the final wish, and instead, consume it into her body so that she could remain the protector of it forever. But by consuming its limitless power, the Jewel turns her into a monster that controls her and makes her kill the innocent and destroy the world. Now in order to save everyone from what she had become, she must seek out the one person who has the power to kill her—Saitama.

Chapter 1: The Girl Shrouded in Darkness
"Stop! Get out of my head!" a girl screamed out in the darkness. "I don't want to kill for you anymore!" The girl gripped her head in frustration as a harrowing voice consumed her mind.
A low chuckle rang out in the dark abyss. "Silly girl, did you really think consuming me would make me stop causing pain and torment?" The voice grew more sinister. "But I guess in a sense, you were correct with making your choice. You have prevented me from harming others, but by consuming me, you have allowed me into your body and mind, so now, you will do my bidding. I no longer have to cause torment if I have you to do it for me." The chuckle grew louder with every distant scream from an innocent.
"No…" The girl curled up into a ball as she continued to float in the darkness. "I never meant for this to happen…" Children and women continued to scream. "I never meant to cause such destruction."
"How does it feel, little Miko? The people you have protected over the years, all dying from your hands," the voice spoke to her. "How does it feel to have so much power, to have so much of my power, but only to use it to kill the innocent?"
The girl covered her ears with her hands to try to get the invading voice from her head, but she knew there was no way to stop the voice from speaking in her mind. "Please…. Stop this…" Tears streamed down her face. "Please…" she weakly pleaded to the unyielding force.
"You brought this upon yourself, Miko. By not making a wish and just consuming me, you have allowed me to continue to exist and live through your mind and soul."
Kagome watched behind tear-filled eyes as she saw villages of people dying from the wrath of the monster she had become. "N-no." She watched as the strongest demons tried to stop her power, but compared to her, they were mere ants to the might she wielded.
She saw her friends try to save anyone they could before they died from the fires caused by her. She saw how others disintegrated from touching the tendrils of darkness coming from her monster. The darkness swept through the village like a horrible plague, killing everyone in its wake. "S-stop!" Kagome began to cry even more. "I said stop!" A young boy disintegrated into ash as the body of the monster consumed him.
The voice let out a menacing laugh. "Fighting is futile. There is nothing you can do to stop this."
Kagome continued to cry. 'There has to be a way to stop it. There just has to be!' After thinking about every possible solution to stop this horrible power, she finally came up with one that might work.
Kagome looked straight ahead at the darkness in front of her with fire in her eyes. "Yes, there is… I believe there is!" Kagome closed her eyes and tried to calm her emotions down. The darkness grew with her negative emotions; the more she fought it the stronger it grew.
'All my life I have been called weak.' Kagome began to meditate and relax her mind. 'There has always been someone stronger than me. Out of all my friends, I was always the one to drag them down...but this time, it will be me who will save everyone.' A bright light began to glow from within her chest.
The monster began to slow down its movement. No longer fueled by the negative emotions of the girl within.
'I was never incredibly strong, or brave, or smart, but with the jewel, I have finally gained power like no other. I am strong now, but at what price?' The bright light began to completely consume her body. 'I know what I must do.'
"Jewel," Kagome said with a commanding voice.
"Hm? Have you finally come to terms of what a monster you have become? Are you going to let me completely take over your very being?" the voice asked with an eager tone, thinking it was finally going to get its way.
Kagome opened her eyes and watched as the fire of the village grew. "I now know a way to get rid of you."
"Get rid of me? But, Miko, we are one now." She could clearly hear the amusement in his voice. "To get rid of me would mean you would have to be destroyed as well, but how are you possibly going to do that if you are now the strongest."
Kagome closed her eyes. "I already thought of that issue. That's why I'll give you the thing you want the most." Kagome opened her eyes again to show the determination in them. "I'll make a wish!"
The voice began to laugh. The laughter grew louder with every passing second. "Yes! Perfect! Once you make the wish, I'll only grow even stronger!"
"That may be so, but it will also make you more vulnerable. With the cost of strength, you'll lose something else."
"There is nothing that is better than being the strongest. Hurry, girl. Make your wish, so that I may rule all!"
Kagome took a deep breath. "I wish for you to take me to the person who has the power to kill us! The person who can finally dispose of the monster that I had become!"
The villagers watched as a void appeared above the monster and began swallowing it up into the darkness of the void. Little by little, the monster disappeared, taking the kind girl they once knew with it.
~In Another Universe~
Two males, a bald man and a cyborg, were fighting in a flat, rocky area far away from the cities to not cause any damage to the buildings and people living there. The cyborg was frustrated with his sensei for not fighting with his full effort, so the bald man quickly showed his naive student why he doesn't use his full strength to fight by destroying a huge chunk of the ridge behind his student.
After throwing his student a powerful punch, but not making contact with him so that he wouldn't completely destroy the cyborg, the bald man went up to him and tapped the stunned cyborg on the forehead. "I'm hungry. It's time for lunch," Saitama said before turning to walk away. "Let's go get some udon."
"OK…" As the man walked away and the cyborg turned to inspect his sensei's handiwork, the ground began to shake violently.
Saitama stood his ground without a care in the world. "Are we having an earthquake?" he asked in a casual tone.
Genos ran up to his mentor. "No, sensei. Look." The cyborg pointed to a black vortex opening up in the air in front of them.
A horrible looking monster made of what looked like shadows came out of the vortex and fell onto the rocky ground with a loud crash, scattering dirt and rocks everywhere. Saitama continued to watch what was going on with a poker face despite the debris hitting him on the head. Genos watched passively as well since he couldn't feel the rocks hitting him anyway due to his body being made of metal.
Once the cloud of dust and dirt had cleared, it was revealed that the monster had created a huge crater in the rocky terrain due to the force of it hitting the earth. With a horrible eardrum-shattering screech, the monster began to get up from its crater and began wreaking havoc to the surrounding area, appearing to not care if any living things were in its way or not.
'My power has finally been released!' a voice said in their heads. 'With the wish made, I am now all-powerful! Ha ha ha ha!'
"Looks like dinner is going to have to wait, Genos," Saitama told his student, still looking at the monster with a passive face.
"It appears so." Genos began charging up his cannons. "Let me take care of it for you, sensei," he said, before quickly shooting himself at the creature, breaking the ground in the process.
Saitama stood there bored as he watched his student fly at the creature and blast at it from all angles. Saitama was sad to say that no matter what Genos did, the monster did not appear to have a single scratch on it. The monster stood its ground, not even bothered by Genos' fire cannons at max level.
"Please…" a female voice spoke in Saitama's mind. "Please stop it. You're the only one who can kill me." Saitama was confused. This woman wanted him to stop the monster, but why would she want him to kill her? And where was she anyway?
Saitama looked closer at the shadow monster and focused in on it. After squinting his eyes, he could finally make out a small glowing shape in the middle of the monster. 'Is she the one controlling the monster?' he thought.
"Please, you're my only hope. If you don't stop it by killing me, it will end up destroying this world. You're the only one who has the power to destroy it."
The woman inside did not seem like she wanted to hurt anyone, but something had turned her into that thing and now she tells him that the only way to get rid of it is to kill her?
Saitama sighed. 'What have I just gotten myself into today?' He shook his head. "Well, better do something about this." Saitama bent his legs to prepare to jump at the monster. With a little of his effort, he propelled himself at the monster at extreme speed, but before he could make contact, the monster easily swatted him away, causing Saitama to crash into the side of the ridge wall.
Saitama quickly plucked himself out of the wall and looked around at the damage that was caused by both the monster and Genos. The whole ridge was practically destroyed around him. "It seems I will have to put in slightly more effort," he said to himself before using the rock wall to push against and shoot at the monster's face.
The second time the hand came up, he was expecting it so he used its hand as something to push off of and reach the face. Saitama pulled his arm back and punched the monster in the face. The punch had left a dent on the monster's cheek, but instead of looking like he was in pain, it just grinned and used one of its tendrils to wrap around Saitama's body and throw him on the ground.
'Fool! You really think a puny human like you can destroy a being like me?' The monster laughed. 'After that stupid girl released my power, I am the most powerful being in the universe! No, in every universe! Ha ha ha ha!' The monster slammed his hand on the ground and began destroying everything around it. 'There is no one who can stop me!'
Saitama picked himself off the ground and sat up in the crater he was in. "Where the hell is Genos?" He looks around and finds Genos in a broken pile a mile away from him. "Huh? Genos! Are you still alive?" Saitama asked his student.
Genos tried to look up despite how broken he was. "I'm alive…but I don't think I can fight anymore."
Saitama stood up. "Just leave it up to me." After standing up, Saitama realized something odd. There was a sudden breeze on his skin. He looked down and saw that his favorite outfit had been disintegrated around the waist and chest area. "My outfit! Don't tell me those tentacle things were made of acid or something." Saitama reached for his torn and destroyed cape and looked at it with upset eyes, before they were suddenly filled with determination and power. "That's it." He let go of his cape and turned back to the monster. "You're going down. No one messes with my outfit."
Saitama bent his legs. "Serious series…" He pushed off the ground with all his might. "Serious jump." He blasted at the monster at what seemed even faster than the speed of sound, if that was even possible. 'I didn't want to do this, but this monster has got to go.' Once he reached the monster, he pulled back his fist again. "Serious punch," he said before punching at the monster. The strength of the punch caused the air from the force of his fist to blast the surrounding area and completely destroy everything. The power behind his punch even forced all of the clouds to blow away from the area, clearing the sky until nothing was left.
Before the punch could make contact with the monster, the creature used its tendrils to wrap around the man's forearm and redirected the punch to the side and away from the monster's body, causing Saitama's punch to destroy the environment for miles in the direction his fist was pointed.
Thousands of miles away from the fight, the force of Saitama's punch had caused the sea to part into two walls of water, revealing the peaks of many mountains that used to be hidden under the sea. The water continued to be pushed up by the force until eventually falling back down with a great force, causing many waves to spread out in every direction.
After Saitama was done releasing his punch, he was shocked that the monster was able to evade his attack and was even able to redirect the powerful punch. Before he could really think about the situation, the monster lifted up his hand and smacked Saitama out of the way, causing the human to fly off at high speeds.
As Saitama sailed through the air and crash into yet another rock wall, he continued to think about what had just happened, not even caring he was being forced through many layers of rock. The force behind the slap was so great that Saitama pushed miles deep into the rock wall, passed miles of tree roots and rock before he finally stopped moving.
Instead of getting up right away, Saitama decided to lay in that hole and think about the past events. 'I have never met someone who could evade my serious punch before. Well, I guess no one actually had to experience that punch in the first place. I never had to use that punch on an enemy so far… But that thing was able to act quickly and handle it like it was nothing…' A smile formed on Saitama's face. 'Have I finally found my match?'
The monster continued to destroy the area and surround forests when a boom was heard from where it had smacked that weird human. 'It seems this human doesn't know when to die,' it mentally said as Saitama jumped at it again and began punching, his fists blurring from the speed of each hit.
No matter how many punches Saitama did, the monster would just reform its body and come at him again, knocking him back yet again. Despite being hit like a fly, the smile never left Saitama's face. 'It seems this was the foe I've been looking for.' He went and hit the monster again. 'What is this feeling?' After he punched, the monster shot it's tendrils to grab the bald man, but before it could, Saitama used its head to jump to its back and punch it there.
When he pulled back his fist to release another punch, he saw a woman with long black hair and a beautiful face lying inside. Her eyes closed and body limp from the monster using her energy. 'So that must be her,' he thought as he dodged another swing from the arm.
"You must kill me. If you destroy my body, he will no longer be able to use me. It is through me that he is able to exist."
He jumped at the monster again and punched multiple times, making sure to avoid where the women was.
"You can't stop him like this."
Saitama was getting a bit annoyed by this girl now. 'Look, lady, I'm not going to kill you if there's another way.'
"But there isn't!" She sounded distressed. "What other way is there? I have tried everything…"
Saitama continued to fight vigorously, no matter how tough the fight was becoming as time went on, he couldn't deny the rush of excitement that went through him. 'Isn't there anything you could do? Does it have any weak points?'
"I don't know… The monster is fueled by my negative emotions and the wish I made. Maybe if I can meditate hard enough and get my emotions to calm down, it'll weaken the monster enough for you to destroy it."
The woman's voice grew quiet. Saitama looked at the place he had seen her body before the shadows covered her yet again. 'It's fueled by her, so that's why she wants me to kill her to stop it.'
Saitama landed on a branch in a tree on the ridge furthest from the monster. 'Hm...Maybe that could work…' Saitama thought back of how he had punched the hole in the monster and revealed the body of the girl lying limp within it. "Hey, girl."
"Yes? I'm trying to meditate."
"That's good. If you can weaken it by doing that, I think I have a solution that doesn't involve killing you," he replied back.
"B-but you must. If you don't, he'll just come back again one day. The two of us are linked."
"Well, I'm not going to take no for an answer. I'm not killing you and that's final." Saitama jumped from the tree with so much force the whole area was destroyed in his wake. "Seal it away or something. If it's part of you, then you just have to be the stronger person and overpower it," he said as he flew toward the shadow creature again.
There was a long pause before he got a soft, "OK" reply from the girl.
With a punch to the face, the creature's head completely blasted off. "It's definitely weaker. She must be doing something right."
The monster was shocked by the impact. 'W-what's going on? What are you doing, stupid girl?' it screamed at her, trying its hardest to use her energy to reform.
"I'm destroying you, Jewel. Without my negative emotions, you have nothing to fuel your darkness!"
As the two of them quarreled, Saitama punched the area where he had seen the girl before. He tried not to put too much force into it just to make sure he wouldn't hurt her. His punch caused the shadows to part and reveal the unconscious girl once more.
After the girl was revealed, Saitama jumped into the stomach but was then quickly encased in darkness from the shadows reforming around them.
With the bald human consumed by the monster, the area was filled with silence.
The monster laughed. 'Fool. Did you suddenly want to get rid of your life so easily you would join me so willingly? Now you will be part of this body and fuel it like the idiotic girl I hold in my grasp.'
Genos was watching the whole thing from the ground. "Sensei…" he said softly, a bit worried for the bald man. He wasn't about to believe his sensei was actually gone and was easily taken out like that. He could still sense his life energy from within the monster.
While the monster continued to laugh and bask in his self-proclaimed win, its stomach began to bulge before it exploded and Saitama jumped out with a figure in his arms.
Once the girl was removed, the creature cried out with what sounded like pain before quickly dissolving into black particles. 'What did you do to me?' the monster mentally shouted, trying to reform again, but with nothing to fuel and facilitate its power, it could not create new body parts.
The floating particles eventually joined together to form a black jewel on the forehead of the girl in Saitama's arms. "Well, that seems to be taken care of," he said calmly. The fight might have been cut short, but that was the most fun Saitama had had in a long time. He had forgotten what it felt like to fight an enemy who could resist his attacks.
Saitama carried the girl bridal style to his broken student on the ground. "Genos, you all right?"
Genos tried to sit up, but he no longer had his arms or legs to lift himself up. "I'm still alive." Saitama set the girl down on the ground as he helped his student sit up. Genos looked down at the girl. "Who is she?" he asked.
Saitama shrugged. "Not sure. She was talking to me from the monster, so I assume she was the one that fueled the monster's power."
"Then why did you not kill her?" Genos questioned.
Saitama gave his student a blank look. "Genos, you don't just kill every monster or person you encounter." Saitama looked down at the girl. "Plus, she didn't seem bad when she talked to me. She kept telling me to kill her, but I told her I wouldn't. She wasn't controlling the monster, it was more like the monster was sucking her energy and using her negative emotions against her."
"So what are you going to do with her?"
Saitama picked up his student with one arm and the girl in the other. "I guess we'll just have to wait for her to wake up so she can explain to us what that creature was." Saitama began to walk off while letting out a sigh. 'Looks like we're not going out for udon tonight.'
Red: Well, that was the first chapter. I hope it has got some of you interested in the story. :P I'm still unsure what the rating of this story should be, but I'll make it M to be safe.
