Arc 1: The Strongest Highschooler- Prologue.


Kuoh Highschool, Japan.

"There they are, catch them!!!" A loud shriek echoed in the corridor of one if the most prestigious institutions in all of Japan as a group of girls, sone barely dressed were chasing two boys with kendo sticks in their hands.

"Motohama, Matsuda, stop running and face punishment for your crimes like men." One of the chasing girls yelled out.

" No way! Last time you caught us, you beat us within an inch of our lives." Matsuda yelled back. As one of the two members of Kuoh's infamous Perverted duo, Matsuda was a well known individual in the school. He was a rather tall fellow with a shaved head.

"Hey! Move out of the way!" Matsuda's partner in crime who was a lanky fellow with medium length black hair and black rimmed glasses yelled out as he was about to crash into someone.

"Ouch!" First Motohama and then Matsuda yelled as their momentum came to a complete halt after a collision. Under normal circumstances, the one they collided with would fall down as well but he showed no sign of having been in a collision.

"Hey man, can't you look where you are walking?" The shock of the collision had temporarily made Motohama forget why he was running in the first place as he stood up the face the obstacle that stood in front of him.

The first thing both of them noticed was the other party's hair, or a distinct lack of hair. His head was almost shining from how bald it was. Both of them could swear that they saw a halo behind his head for a second.

"Get ready for your punishment." The momentary distraction had been more than enough for the Kendo club girls to catch up. As they were being dragged off towards the backyard to serve their punishment, the only thing in the Perverted duo's mind was that perfect egg shaped head.


"Man, there's a lot of weirdos in this school." Seventeen year old Issei Hyoudou mused as he walked through the hallways of Kuoh Highschool. The incident with the Perverted duo was quite a common occurrence although it was the first time Issei had been personally involved in it.

As a second year student in the highschool division of Kuoh, he was well aware of the student populace's love for giving out nicknames. He had heard about the Two Great Ladies, The Academy's Prince, The school mascot etc.. from his classmates. He was even referred to as chrome dome by a few of his male acquaintances. It wasn't a particularly pleasant name but he tolerated it since his hair loss was partially his own fault as well.

You see, it all started when Issei was twelve. While playing at the park with his friends, he had ran into an old man who asked if he wanted strength. Being the simple minded fellow that he was, he agreed immediately and was given a training schedule which in hindsight should not have worked now that he thought about it.

It consisted of 100 push ups, 100 sit-ups, 100 squats and a 10km run everyday. He had struggled really hard to complete it at first since he hadn't worked out before but for some reason he managed to push through the pain and the problems and continue his training. By the fourth month, his body had completely become used to the training and he didn't struggle at all. However, his master had asked him specifically not to increase the number of exercises so he stuck to the routine. Everything was going normally but by the end of the first year, he had started to notice anomalies in his body. His hairline was starting to become thin and he lost a lot of volume in his hair. However, he continued on with his training and so, at the tender age if fourteen, he lost his hair completely.

His parents were worried that he had some disease and took him to a check-up in a nearby hospital which ended up in complete failure when the needle required to check his blood sample failed to pierce his skin. This was one of the indicators that he was becoming strong although he was nowhere near as strong as his master.

By the end of the third year, his master had left claiming that Issei had become strong. Although he didn't have the opportunity to fight most of the time, the few fights he had ended up in ended with one punch even though he was holding back quite a lot. Now, Issei was no battle maniac but he still wanted to enjoy fighting once in a while.

When he was in the third year of Junior highschool, Kuoh Academy, a prestigious all-girls school made the decision to become a co-ed school due to the declining admission rates. As someone who lived ten minutes away from the Academy, he naturally applied for admission and to his and his parents' surprise, he ended up passing the admission test. He was one among the first male students to step foot inside the prestigious school.


As a former girls only school, Issei had a lot of expectations about Kuoh from some of the shoujo anime he used to watch as a kid but he wasn't really prepared for what was about to come.

Kuoh's student populace, for the lack of a better word was weird. Now, he wasn't the paragon of normality himself given his abnormal physical prowess but even si the sheer number of open and closeted perverts around him was staggering. This wasn't to say that there weren't any normal people around but he estimated that at least eighty percent of student population were pervs. The third year girls were openly gay for the two great ladies of Kuoh which wasn't their fault since the ladies in question was beautiful beyond words. If it wasn't for his distinct lack of strong emotions recently, he might very well have ran after them.

The second year and first year girls were mostly divided between the straight faction that idolised Yuuto Kiba, the so called Knight of Kuoh and the Yuri faction which worshipped the Two Great Ladies as well but both sides were equally depraved.


"Good morning Issei."

"Good morning Ms Katase. I presume you have dealt with those guys. "

As he entered the classroom, he greeted his desk neighbour. Katase, whose first name was still unknown to him was a member of the Kendo club who was involved in the beating that witnessed in the morning. She had short pinkish brown hair and was relatively well endowed for a high school girl, a pattern he noticed was quite common in Kuoh.

"Those guys are simply the worst." Katase complained. "If they put in half the effort they put into peeping for studying, they might become the top students in our year." She sighed.

"I see. My condolences. It must be troublesome to deal with that everytime after practice." Issei wasn't a Kendo practitioner by any means as he had almost murdered someone accidentally while wielding a stick before. Although he was well versed in controlling his body, weapons in his hand was impossible to control.

Katase sighed in response before turning her attention to her friends which was his cue to end the conversation. Since Matase was one of the very few people he talked with, all he could do was stare out the window before the teacher came.


The day passed by uneventfully and soon it was time to head home. Although he could reach there in seconds if he really wanted to, he was starting to like the slow walk home. Perhaps his hair loss was making him think like an old man.

As he walked out of the classroom, he greeted a few classmates whose names he didn't know. His journey however came to an abrupt end when he came face to face with a girl who was blocking his path.

The girl in question was quite cute with black hair, violet eyes and a well endowed chest which looked unrealistic for her age as she barely looked over sixteen. She was wearing a uniform that didn't belong to Kuoh so he guessed that she studied somewhere else.

"Can I help you miss?" He asked politely.

"Please go out with me Issei-senpai!" Out of nowhere, he was hit with a confession.

"I'm sorry but have we met before?" He was genuinely confused as he hadn't seen this girl before at all.

"My name's Amano Yuuma. I fell in love with senpai at first sight. Please go out with me." The girl practically begged.

Now, if he was a normal person, there was two possible ways this would have gone, either he goes over the moon due to being confessed to by a beautiful girl or be skeptical about the whole thing. However, he had nothing to lose accepting the confession and so he said. " Fine, I'll go out with you. Let's go on a date this Saturday." Although something felt off about the whole thing, he agreed. It wasn't like she could hurt him even if she wanted to.


"Thank you senpai." The girl practically bounced off.

And so, Issei Hyoudou, at the tender age of Seventeen got his first girlfriend.


The week passed by like normal and soon it was the day of the promised date. His mother was ecstatic when she heard that her son managed to find a date so much so that she went ahead and bought new clothes for the date. He soon dressed up in the casual dress which his mother had bought for him and reached the place of appointment. He was ten minutes early which his mother was adamant that he be, something he found to be tedious but went with the flow anyway.

"Here, take this. It can make any of your wishes come true." As he was standing waiting for his date, he was approached by a rather shady looking girl who was handing out something that looked like a pamphlet with weird symbols on it. Given his history of dealing with shady individuals, he took one from her after which the girl went away leaving him to his devices. There wasn't ay explanation on how it worked or anything, she just left.

After about ten minutes of waiting, Yuuma arrived wearing a white one piece dress and a black beach hat. "Sorry I'm late senpai. Did you wait long?" She asked.

"Don't worry about it, I just got here." Was supposedly the standard reply according to his mother. "Let's just get on with it." He said. And so, their first date officially began.


To be fair to Yuuma, their date wasn't half bad. Although his struggle with the ability to feel strong emotions held him back from enjoying it to the fullest, she did look like she was having good fun. The entire day passed by quickly and as evening cane, they walked into a rather secluded part of the park in the centre of the City.

"The date was wonderful senpai. I had a lot of fun." The girl beamed. "Could you do me a favour senpai?" She asked.

"Depends on what the favour is."

" Could you please die for me? " She murmured in a low voice with her head down which his hearing picked up regardless.

" I think I heard it wrong, could you please repeat that again? "

" I said, could you please die for me. " As she said it, Yuuma raised her head. The cute looking young girl was gone and in her place stood a deranged girl with a sadistic glint in her eyes.

Before he could ask her what was going on a light flashed in his field of vision and the girl poked him with a stick made of light which to his complete and utter horror, tore a hole in his newly acquired shirt.

"What the?! " The girl exclaimed as she looked dumbfounded by the sequence of events that took place. However, she didn't have much time to contemplate her decisions as she was hit with a blast of pure killing intent that made her hair stand on end.

"You're gonna pay for that you know." Issei was calm as he said this.

"Who the fuck are you?! How did you survive that?!" The well mannered girl was completely gone. Before he could reply, the girl was covered in some sort of light which looked awfully similiar to a magical girl transformation. And true to his word, the girl really did transform after the light disappeared. He normal attire was gone and in its place she now wore a dress that looked like it came from some sort of hardcore sadomasochist porn. Also, she now had wings for some reason which looked like it belonged to a crow.

"Might I ask what exactly you are? Cause you certainly don't look like a human." He asked the girl who was still weary of him.

"I am a fallen angel you dumb human and I was tasked with your extermination." At least she was cooperative.

"Fallen angel? Like in the Christian mythology?" He wasn't particularly well versed in mythology but he still knew a little. However the girl or rather the fallen angel didn't seem like she was in a mood for further conversation as she she attacked him with her light stick. After a few failed attempts at poking a hole in his stomach, she relented and fell back while holding the light stick up.

" What are you?! " The girl was on the verge of despair.

" What I am doesn't matter. What matters is the fact that you are not human. Di you know what that means? " He asked as his facial features suddenly sharpened.

" No... " The fallen gulped her saliva audibly.

" It means that I can punch you without issue. " Before the girl could reply Issei was in front of her face almost as if he teleported. Before she could beg for mercy, a punch landed in her abdomen after which two events took place. The fallen splattered into chunks of meat and the shockwave generated by the punch decimated a few trees in the line of fire.

"That was way too easy. And I even held back too." Issei mused as he looked at his creation. He had punched the now deceased fallen angel harder than he would a human but he still had held back a lot. However, he didn't feel any particular remorse over the death as she had tried to kill him. Leaving the problem of the clean-up to somebody else, ge left the park not knowing that his life was never going to be the same.

Will he ever find someone who could fight him? Who knows .


Hello. This is my pretty sad attempt at writing a different Issei with elements from one punch man mixed into it. I might continue this later depending on the response.

PS: It's been almost a year and a half since I wrote something in this site and with fanfiction reverting the notification settings, I completely forgot about it. Not that I was good at writing before but it was at least better than this.
