A/N: This is my first attempt at writing anything featuring male/female pairing. And not even that, it is my very first harem fic. As such, you shouldn't think too deeply about the plot and just enjoy the story. No M rated content here so far but future chapters will contain some yuri and some lemon. Please review after reading.

The Day It All Changed

It was a completely normal day for Kinji. Nothing was out of order and everything was just as it's supposed to be. Kinji had no way of knowing that before the day ends, his life will be changed forever. Or maybe he knew but was powerless to change his fate. It all happened quite coincidentally. The odds were surely close to zero but it happened. On that one fateful day, the life of Kinji Tohyama was irreversibly changed along with three different lives. Three innocent souls trapped in the wheel of fate, revolving around the one single existence. The change was a great one yet not a single being except those four was able to notice it. On that day, everything changed. On that day, nothing changed. On that day, their fate was sealed. On that day, Tohyama Kinji ceased to exist.

"Oh man! I'm going to be late again!" Kinji screamed once he saw the time at the clock.
For some strange reason, the alarm didn't ring and as a result, Kinji slept in. He cursed his bad luck as he leapt out of his bed and started dressing up frantically. At that time, a thought crossed Kinji's mind.
Why didn't Aria wake me up? She always gets up on time even without the alarm.
He glanced at Aria's bed and froze. Aria was lying in her bed with a peaceful expression on her face.
Oh crap. She's going to be mad. I better wake her up.
Kinji quickly jumped to Aria and shook her tiny little body. He shouted: "Aria! Wake up! Aria! We're going to be late!"
However, to Kinji's surprise, Aria only tossed around and mumbled: "Let me sleep."
Determined to wake her up, Kinji continued: "What are you saying? This is no time to be sleeping! Do you want your perfect record to be broken?"
And then, without thinking, Kinji grabbed Aria's blanket and yanked. Before he could realize what has he done, Aria was awake. Kinji now had complete view on Aria's body, covered only by thin nightshirt. Kinji felt his hysteria mode kicking in. He hated entering hysteria mode. It cleared his head and made him capable of super-human feats but also made him act suave and play hero for the girls. Not to mention that the only way to activate it is by being turned on. He quickly averted his gaze and tried to throw the blanket back at Aria but it was too late.
"You idiot! Pervert! Scum! Trash! Die!" Aria was spewing one insult after another while desperately trying to cover herself.
Kinji tried to defend himself: "No! Wait! It's not how it seems! You see, the alarm didn't ring and—"
Aria made no effort to let Kinji explain himself and lunged at him. Unfortunately for her, it was at exactly the same time that Kinji tried to cover her with the blanket. She got caught up in the sheet and fell back to her bed. Kinji, who was holding the blanket the whole time had no time to react as the falling blanket dragged him along. His legs slipped and he felt himself falling uncontrollably towards Aria. As a last resort, he waved his arms in desperate attempt to grab something but all he managed to do was speed up his fall.

Kinji felt his face sink into something warm and soft. It smelled nice. It was only then that he realized he fell on Aria's chest. The feeling was too great and Kinji entered Hysteria mode. His head calm and calculating, he rose from Aria in a slow and calm motion. Aria's face was red with embarrassment and it looked like she has trouble finding the right words. Without saying another word, Kinji went to the dresser and carefully grabbed Aria's clothes. He then turned around to the girl and spoke: "I had to wake you up. The alarm didn't ring and we overslept. It would be a shame if your perfect record got tarnished, don't you think?"
Aria blinked in surprise. She opened her mouth before closing her again. Kinji calmly set the clothes next to her and urged her to get dressed. Finally, it seemed like Aria got a grip on the situation because her face contorted into an angry grimace and she shouted as loud as she could: "W-W-Wha… You IDIOT! It's Saturday!"

Later on, Kinji and Aria decided to spend the day going to a nearby amusement park. Fortunately for Kinji, accidents like the one in the morning weren't all that uncommon for them so they quickly forgot about it. However, what Kinji couldn't have known was that the morning accident was only the beginning.

Kinji and Aria paid for the tickets at the entrance and went in. Aria was like a little kid, looking around at all the booths and rides around them. She turned to Kinji with glistening eyes and yelled joyously: "I want to try them all!"
Kinji shrugged his shoulders and responded: "Do as you wish. I won't stop you."
"What are you talking about? You're going to try it all as well!"
"Wait! Wha—" But before Kinji could ask his question, Aria already dashed off. Kinji hurried after her. Fortunately, her small stature made it quite easy for Kinji to keep track of Aria. She ran from booth to booth, obviously enjoying herself. Although she said he was going to participate as well, in the end all Kinji could do was watch over her from the distance. She was way too fast for him to catch up and try his hand at a booth or go on a ride with her. It was after her third ride that it happened.

Aria was running around a fountain when Kinji saw a kid on roller-skates speeding uncontrollably towards her position. He saw that crash was imminent and started to run. However, he was too far from Aria and before he could shout and warn her, the kid rammed into Aria. The impact lifted the girl off her feet and sent her flying straight into the fountain. Several people gasped in surprise at the unexpected commotion and the culprit himself skated away as fast as he could. Kinji screamed and doubled his speed. When he got to the fountain, Aria already lifted her torso up and was now sitting in the fountain. She looked dizzy and it seemed like she doesn't fully understand what happened. However, the first thing that caught Kinji's eye was Aria's clothes. They were now completely drenched and clung to Aria's skin tightly. He could clearly see Aria's skin and her bra through the clothes. Kinji thought of only one thing as his Hysteria mode started. Oh crap.

Ignoring the many bystanders who were now whispering amongst themselves and pointing towards Aria, Kinji closed the remaining distance and leaned over the edge of the fountain. It seemed that Aria finally realized what happened and she looked like she could cry at any minute. In one fast smooth move, Kinji gently grabbed Aria's tiny body in his arms and lifted her off the fountain. Unsurprisingly, Aria struggled and protested: "What are you doing? P-Put me down! Idiot! What will the people think?"
However, Kinji held Aria tightly and started walking away without a word. Aria beat her fists on his chest but it had no effect. After a short while, she calmed down a bit and resigned her futile effort to get free.
"Just do whatever you wish. Idiot." Aria mumbled and blushed slightly.
Kinji didn't let go of her even when they reached the door to the dormitory. Only after he opened the door to the bathroom did he let go of Aria and said: "Take a shower. I'll bring you some spare clothes in the meantime."
Aria nodded slightly and started undressing. Kinji closed the door and wiped his forehead.
Damn, that was close. My hysteria mode ran out long ago already but I had to keep up the façade or she would have killed me. Now, to bring her the clothes.

Kinji waited patiently for Aria to come out, so he could explain his actions. However when the doors to the bathroom opened, Aria dashed to the main doors and said: "I'm going out." She slipped past the door and slammed them closed. Kinji was left with his mouth half opened as his brain tried to understand what just happened. Suddenly, Kinji heard a ringing noise. He jumped a bit in surprise and ran to the door before realizing it wasn't the doorbell he heard but an SMS notice. He reached to his picked and pulled out his cellphone. Kinji's fingers quickly browsed through the menu and to the message. He quickly read it and typed a short response before leaving the house as well.

"So, why did you call me here?" Kinji growled discontentedly as he entered the room. It was a small room inside a karaoke building. According to the receptionist, the room he was in was known for being the most favorite among lovers. It didn't really surprise Kinji to learn that. In fact, he was expecting something similar. It's always the same with her. He sighed deeply and repeated his question: "Why did you call me here, Riko?"
The blonde-haired girl giggled and rolled over the sofa she was lying on. "You don't know Ki-kun? It was you who asked me for that information, right?"
"Of course I know about that. I mean why do we have to meet here of all places." Kinji sat on the other end of the sofa, effectively maximizing the possible distance between him and Riko. However, Riko quickly scuttled over and sat right next to him, much to Kinji's dismay. She pressed herself tightly on Kinji's side and announced without a care: "That's because Ki-kun and Riko are going out together, right?"
Kinji could feel his face heat red as he blurted out: "Wha- Don't be stupid! No way in hell is that true!"
Riko giggled again, apparently amused by Kinji's reaction. She lifted herself from Kinji and smiled brightly. "Just kidding, I was just kidding."
Kinji exhaled deeply and pierced Riko with a fiery glare: "I would appreciate it if you let me know beforehand before making tasteless jokes. Now, where's that info?"
Riko waved her finger in front of Kinji's head like she was scolding a child and said: "Non, non, Ki-kun. Nothing is ever free and information can be quite expensive."
Kinji made a disgusted face. He knew this was going to happen. She's probably going to want some ridiculous or embarrassing stuff again. It was like this all the time and so Kinji wasn't surprised when Riko told him her price: "Sing some karaoke with me!"
"Huh?"
"Ka-ra-o-ke! Let's sing, Ki-kun!"
Kinji looked at Riko suspiciously but he knew better than to argue with her. He picked up the microphone and picked a random song from the list. He and Riko sung alternately for several minutes when Kinji announced: "All right, I think that's enough."
Riko's face darkened for a second but she quickly brightened up again. "All right. Let me just sing one more song."
Kinji shrugged his shoulders and said: "Whatever. But it's the last one."
Riko nodded happily and picked her song. A slow, sensual melody started playing from the speakers. Kinji expected Riko to sing while looking at the TV but she suddenly climbed on the table in the middle of the room and turned towards Kinji. She slowly started to move her hips in rhythm while singing. As the song progressed, her dance grew more wild and bold with each second. Kinji watched in amazement as Riko danced in more and more exposing ways. He felt Hysteria mode starting. Kinji desperately closed his eyes to try and prevent entering Hysteria mode. Suddenly, he felt something land on his lap. He opened his eyes and saw that Riko was now sitting on his lap with her legs wide apart. Kinji opened his mouth to say something but before he could do so, Riko leaned towards him and kissed him. That was the last straw and Kinji entered Hysteria mode. He grabbed Riko's wrist and gently pushed her off him. She fell on her knees and looked up on him like a sad puppy. When Kinji spoke, his voice was calm and showed no sign of his previous frustration: "I think that's enough fooling around. Give me the info please."
Kinji's gaze made it clear he won't accept any more delays. Riko stuck out her tongue in a cute way and reached into her cleavage. She picked up a thin paper she stashed there and pulled it out. Kinji took the paper and placed it into his pocket. He opened the door and stepped out. Before closing the doors, he turned around and smiled at Riko: "It was a fun karaoke. You were amazing."

Kinji cursed his stupid behavior all the way to the dormitory. He was looking forward to lying on the bed and relaxing for a while. He opened the door and went in. Kinji noticed that Aria's shoes on the ground so he moved around quietly. Bumping into Aria was the last thing he wanted right now. If everything goes right, he will be able to slip into his bed and sleep before she notices his arrival. That's what Kinji hoped for. He carefully threaded, taking care not to make any single sound. He reached the bedroom door and slowly opened them. Then time froze. Kinji's gaze was met by Aria's. She was standing in the center of the bedroom, looking right into Kinji's eyes. She was dressed only in her bra and panties. Just that sight alone almost triggered Kinji's Hysteria mode. For a while, those two stared at each other before their faces reddened in embarrassment. Kinji tried to quickly slam the door but Aria was quicker.
"You pervert! I'm going to kill you!" She screamed as she run to Kinji. Before he could do anything, Aria jumped on him, locked his neck in between her legs and crashed him down to the ground while still sitting on him. Unfortunately for Kinji, Aria's crotch was now directly in front of him. Before his brain took up all the recent events, he was already in Hysteria mode. Aria lifter her fists and tried to smack Kinji in his face but he effortlessly caught her arms. She struggled to get free but Kinji was much bigger and stronger than she was. He had no trouble raising Aria off himself and setting her down on the bed. He quickly threw a blanket over her and switched off the lights. Aria shouted and kicked but Kinji didn't pay any attention as he swiftly made his escape. He ran out of the dormitory and onto the street. He waited for several seconds and then carefully looked behind himself. Nobody was there. Kinji turned his head back and let out a surprised scream when he saw a girl's face in front of him. Fortunately, it was not Aria. Kinji wiped his forehead in relief and asked the girl: "S-Shirayuki… What are you doing here?"
The girl blushed slightly and tilted her head toward the ground. "I-I'm just going back to my dorm from some shopping. How about you, Kin-chan?"
"Ah… N-Nothing. I just got in a little fight with Aria so I'm taking a walk, that's all."
Shirayuki fidgeted nervously and asked with a shaking voice: "Ummm… K-Kin-chan… D-D-Do you want to come to my place for a while?"
Kinji started to refuse the offer but when he saw Shirayuki's expression, he could only nod and add: "Okay. I'll go."
Shirayuki's face lightened up immediately and she led him enthusiastically to her dormitory.

Kinji and Shirayuki were kneeling on a pillow next to a short table. They each had a cup of warm tea on the table. After some time of rather awkward silence, Shirayuki finally asked the question she wanted to ask for a long time: "Kin-chan. You and Aria… what is the relationship between you two?"
Kinji stiffened at the sudden question and laughed nervously. He forced his face into an uninterested expression and said: "We're just… partners. Partners. Nothing more, nothing less."
The girl didn't seem convinced as she glared at Kinji suspiciously. Her gaze seemed almost threatening. Shirayuki continued in her questioning mercilessly: "Partners? But didn't she call you her slave?"
Shirayuki's voice was menacing and Kinji could feel dark aura rise around her. He was sure that if jealousy ever had a form, it would be Shirayuki. He tried to think up some way to explain but he was too slow. The beauty before him already interpreted his silence as an acknowledgement. Her eyes burned with a fiery rage but that rage wasn't directed at Kinji. She talked with increasingly louder voice: "So it's true... Kin-chan, do you like this kind of play?"
"W-What? No, I—" Kinji managed to form some kind of defense but Shirayuki ignored him completely and resumed her assault.
"You know, I wouldn't mind being your slave, if that is your thing. I would be happy to do so. You don't have to suffer from that girl's oppression." Shirayuki crawled closer and closer to Kinji until she was right before him. She placed her hands on his shoulders and looked directly into his eyes. Kinji gulped and tried to crawl away but she held him in place firmly. He looked down on Shirayuki and noticed he can see her bra from the angle. Before he could reprimand himself, Kinji felt Hysteria mode starting. He averted his gaze and frantically thought about various unrelated things to lower his arousal. It was then that Shirayuki said those words that started all the events to come: "Kin-chan. I'd gladly give you my soul and my body. You can do whatever you wish with me."
The last thing Kinji thought about before his vision blackened were the words his brother said to him once: "Kinji. No matter what happens, you must never enter Hysteria mode five times in the same day. The strain it would put on your brain is too great. You will forever lose yourself. Remember this clearly. Never enter Hysteria mode five times in one day."
Kinji thought about the words of his brother as he entered the Hysteria mode for the fifth time that day.
