Hi everyone! After a long time, I finally write a new chapter for this story! But I've to warn you first. This story is no longer a remake, but a reboot. The first 3 chapters were meant to be remake of the beginning of The bully and the bullied (the first 6 chapters) since I wasn't satisfy with it when I reread the story. But I don't want to redo all of the story since I like the plot. It's more the evolution of the relationship between Shiena and Otoya that I feel wasn't enough developped (I was younger when I wrote this story, and kind of immature). So from now, this story will serve as a reboot focus on the OtoShie pairing rather than a elaborate plot storyline like the original story. I hope you'll like it!

Warning: I made reference to some mental conditions in this chapter. If you are a specialist in those, you may be triggered by the fact that I might be wrong about them.

"Psychopathy…" Shiena mumbled while typing this word on her keyboard.

It was early in the morning. The brunette woke up recently and before she had to go to school, she decided to do a research on the Internet. Otoya was currently still asleep in her bed. No, it wasn't because they had sex last night. There didn't have anything sexual between Shiena and Otoya since the day the serial killer assaulted her. The reason why she was sleeping there was because Otoya had become accustomed to go slip inside of Shiena's bed after the brunette fell asleep. Strangely, the serial killer never tried to do something wrong or inappropriate when they were both sleeping in the same bed, but she cuddled a lot when she was asleep. Shiena would be lying if she said that she fully disliked this.

Shiena developed a desire to understand more Otoya. Not because she really cared about her, but for her own safety. It was quite obvious that Otoya had some kind of mental problem. Someone who was able to commit such atrocities like cruelly murdering people and enjoyed it was certainly not a sane person. If the brunette managed to understand how Otoya's mind was working, she should be able to protect herself more adequately. When you are living with a serial killer, you needed to be cautious. If she had to be stuck with Otoya, she had to take her precaution.

The hacker checked some websites about psychopathy. She highly suspected Otoya to be a psychopath. From what she knew about this condition, the serial killer could be one.

"Let's see what this website says about this." Shiena said before reading. "The major traits of psychopaths are the lack of empathy, their manipulations skills and their ability to present a fake personality. They are also often quite intelligent, charismatic and are fearless."

Until now, it was fitting Otoya's personality and behavior.

"Unlike how they are represented in the media, psychopaths aren't necessarily emotionless or sadistic." Shiena continued to read. "Psychopaths are often portrayed as evil criminals in TV shows, such as murderers and serial killers. The majority of the people in reality who are psychopathic aren't dangerous and do not commit murder. They are also way more psychopaths who are men than women."

Well, in Otoya's case, she was sadistic and a serial killer who had committed multiple murders, and she was certainly dangerous. But she didn't seem to be emotionless. And if this statistic was true, Otoya was among the rare case of psychopathic women.

Shiena sighed. It seemed that Otoya was most likely a psychopath. She looked at other websites to be sure and they pretty much said the same stuff. The only other information she found was the fact that the term psychopath, as well as sociopath, weren't actual medical terms and that the real term for those conditions was antisocial personality disorder. The brunette wasn't sure if she should be relieved or worried about this.

"I'm…living with a psychopath. A psychopath who had sexually assaulted me and hurt me, who's currently sleeping in my bed…a psychopath who claimed to be in love with me…uh?"

Shiena suddenly thought about something and she quickly typed another researched.

"Can psychopaths feel love?"

Shiena found multiple different answers to her question. Some websites said that psychopaths can't understand human emotions but they are still able to have feelings, so they could feel love but they wouldn't express it normally. Other websites said that they can feel love, but with their lack of empathy, they'll be most likely abusive or manipulative toward their romantic partners, and she also read that couples where one of the partners is psychopathic often don't last long and that psychopaths usually had short relationships since they got bored of their partner easily. On a brighter note, she also found a website that claimed that psychopaths could fall in love and developed a strong bond with their partner, especially if their lover is aware of their condition and accepted them for who they are.

Even if Shiena would want to have hope about the last information she found, she doubted that it could the case for Otoya. The purple haired girl wasn't in the majority of psychopaths who were harmless. She was a serial killer who displayed sadism and cruelty, she actually felt sexual pleasure into killing painfully others. But at least, all the information she found seemed to confirm that psychopaths could love, so Otoya might be honest about her feelings for her. But still, even if she was currently in love with Shiena, it didn't mean that it was necessarily a good thing. The serial killer might get bored of her and eventually kill her.

The brunette hoped to reassure herself with her researched, but it had the opposite effect. She was now more afraid of the unpredictable potential psychopath Otoya could be. She didn't have the time to think about it more since it was now time for her to go to school. Shiena put her uniform and left her apartment, still worried about how her relationship with Otoya.

When she was at school, Shiena had used her free time during lunch time to continue her researched at the library. She wanted to know more about psychopaths like Otoya, those who felt sexual pleasure into killing. She found out a rather disturbing paraphilia that a lot of psychopathic serial killer had.

"Ero…to…phonophilia…?"

This paraphilia name was erotophonophilia, also known as lust murder. It was a sexual disorder that consisted of feeling sexual arousal when killing. It seemed to fit Otoya perfectly. According to what she read, this paraphilia could be treated, but with therapies.

Shiena couldn't search more since lunch time was now over. So she planned to continue her researches when she'll be back to her home.

But she couldn't.

When she went inside her apartment, the brunette had only the time to remove her shoes and walked few steps before being slammed against the wall.

"Why are you coming home so late?"

It took few seconds for Shiena to realise what was happening. Otoya had shoved her against the wall while gazing at her with a cold expression. She was restraining the brunette by holding both her wrists with one hand against the wall above her head.

"Uh? Coming home…so late?"

"Yes! It's 20h! Aren't you supposed to finish school at 15h? What take you so long!?" Otoya asked.

"My part-time job…I had to work this evening…"

"Where?"

"In a…manga café."

Shiena didn't like how Otoya was gazing at her. The serial killer had a predatory gaze, which made the brunette uncomfortable.

"You weren't there when I woke up this morning." Otoya complained.

"You were still asleep when I had to go to school."

"You left me alone for such a long time…"

"Like I said, I had to work this evening."

"…I had a lot of time to think about what I'm going to do to do."

"Uh…?"

Shiena suddenly felt something between her legs. She realised that it was Otoya's knee that was pressed against the wall, dangerously near the brunette's crotch.

"Takechi, what are you doing…?!"

The serial killer didn't answer and with her valid hand she began to stroke Shiena's belly and ribs through her shirt, must to the hacker's annoyance.

"Takechi, I'm serious, cut this out!"

But of course, Otoya didn't listen. A smirk appeared on the serial killer's lips and her eyes were only expressing lust. Her hand slipped under Shiena's shirt. The brunette could feel her fingers slightly touching her bare skin and dangerously aiming to her skirt.

Shiena knew that words would probably not made Otoya changed her mind. The serial killer was beyond reasoning in her current state. The brunette could thought of only one way that could possibly made her stop from her own will.

"Takechi, no." Shiena said firmly.

The brunette did her best to gaze Otoya right in the eyes the most austere she could. The serial killer seemed confuse, before she looked at her with displease. She then grabbed Shiena's chin and approached her face from her while grinning.

"Did you say something?" Otoya taunted.

"I said no." Shiena replied with the same tone of voice than earlier.

This time, the serial killer looked pissed. She suddenly raised her knee and began to stroke it against Shiena's crotch. The brunette had to bite her tongue to refrain herself from moaning. She didn't want to utter the slightest sound that could please Otoya.

Shiena viewed her fundamentally as a bully. The hacker had known enough bullies to know what they are after; reactions. And not any reaction, the one they are expecting from you due to their bullying. Usually it was anger, fear, and even sadness, but certainly not indifference. Shiena was asking her to stop not with anger or fear, but with a lack of concern about her. She knew that causing anger to someone amused Otoya, fear gave her joy and the pain of others was arousing.

According to what she had read, psychopaths don't felt emotions normally, it's in fact usually the opposite of how a normal people should feel them. When you are hurting someone, you're supposed to feel guilty, while when you are helping others you usually felt good. Well, it seemed to be the opposite for psychopaths, which could explained Otoya's lack of remorse and even pleasure into killing and hurting others.

"Shiena-chan…don't try to act tough. I know you like it."

This time, the brunette didn't even bother to reply, which seemed to annoy greatly Otoya. Shiena continued to look at her with a cold stare. She grabbed the hacker's tie and pulled her closer to her with a threatening look.

"Why do you keep silent!? Why are looking at me with those eyes!? Would you prefer that I touch you with the blade of my scissors?!" Otoya shouted.

That's it, Shiena managed to get her mad, which wasn't a bad thing. She had notice that when Otoya was annoyed and pissed, she was more likely to be verbally aggressive rather than physically aggressive, and it seemed to be a huge turned off for her. Considering that Otoya's motivation to hurt others was to gain sexual pleasure, to make her in a state she couldn't be sexually aroused was a good way to avoid being attacked.

"I'm going to fuck you with my scissors…!"

"Is it really how you should act with someone you claim to love?" Shiena replied with contempt.

Otoya looked shock for a moment. She then released Shiena and recoiled. Judging by her confused expression, the serial killer didn't know what to reply.

"Do you seriously think that it's right to treat others like that?" Shiena questioned.

"Uh…treat others like…what?"

"I mean hurting others. Do you seriously think it was ok for you to kill all those girls? Can you at least understand how wrong it is?"

"Well I liked it so how could it be wrong if it brought me pleasure?"

"Because you had to kill for that! You caused pain to your victims but also to their relatives! Don't you feel bad for them?!"

"Meh, not really. It's not like I knew or cared about them."

"What about the value of life!?"

"It's bullshit. Life has no value. People choose which lives matter to them, this is the proof that it's subjective. At least their death had a meaning for me. I do find value into death though. But I do value your life, because you matter to me."

Shiena felt her heart racing. She didn't want to feel that way, but with this sudden confession she could not help but be moved. She still managed to keep her composure and didn't show it to Otoya.

"How would you feel if someone hurt you?" The brunette asked.

"I would kill that bastard, why?"

"I'll say it in another way. If a serial killer attacks you with the intent of slowly torturing you to death, would you like it?"

"Of course not! Why are you asking such a stupid question?"

"Because it's exactly what you're doing to others!"

"I…am not sure to get your point."

"Urgh…Ok. What if someone killed me, what would you…"

"Why are you talking about such a thing!? I wouldn't let that happen and killed this person!"

Shiena understood that it was vain. Either Otoya was dense or she really had zero empathy. But she was kind of happy to hear that she would protect her if someone wanted to kill her.

"I know that you were trying to change the subject. Why do you have to work the evening? You're leaving me alone almost all the day! Quit your job and give me more attention!" Otoya ordered.

"What? No! I need that job, I need money to live. And I need it even more since I've an unwanted guest in my apartment now…"

"Eh, what unwanted guest…?"

"I'm talking about you! Who else could it be?"

"I don't know, the spider behind you."

Shiena literally jumped when she heard that. She quickly walked away from the wall and turned back. The serial killer wasn't lying. There was a big spider on the wall.

"Uh? You're scared of spiders, Shiena-chan?"

The brunette didn't even reply. She immediately went to the opposite side of her apartment, far away from the spider.

"I suppose it means yes. Seriously, I can't understand how people can be scared of such a small and harmless creature. Sure they are ugly, but I still don't get it." Otoya said.

"Aren't you scared of something? Do you have fears?"

"Uh? Well, there's not a lot of thing that scared me…maybe cops? Not that they scared me, but going to prison sucks."

"So you really are fearless…Anyway, can you please do something with this spider?"

"Like what? Killing it?" she asked with a somewhat bothered expression.

"…I…I don't care. Just get it out of my sight. Put it outside if you want, but I don't want this in my apartment!"

Otoya seemed kind of curious about her behavior. Shen then took the spider with bare hands and went to the window. She opened it and dropped the spider outside before closing it.

Shiena was honestly surprised. Otoya actually did something nice. Sure she doubted that it was because she felt empathy toward her fear, but at least she listened to her request. The serial killer could have been mean and cruel and choose to use the spider to torment Shiena, but she didn't. The hacker felt a rush of warm in her cheeks, like she was blushing.

"Well, now that's done, we can continue what we were talking about…" Otoya began to say.

On a whim, Shiena approached from her and gave her a sudden kiss on the lips. The serial killer didn't protest, she even kissed her back. But in her case, it was a French kiss.

Their kiss continued for what seemed to be a long moment. It was so sensual and exciting, Shiena was kind of aroused by that. Fearing that it would end up too much intimate, the brunette suddenly broke the kiss. Otoya looked at her with confusion, but also with an obvious arousal.

"Wow…that was good. But…why so suddenly?" the serial killer asked.

"Because…I wanted to. You were nice to me so it made me want to kiss you."

"Uh? Eh, ok…anyway, it was great!"

Otoya seemed to have difficulty to associate the fact she did something nice with the kiss, which was in fact a reward for her good action. Maybe if Shiena kept that up, Otoya will eventually learned.

Shiena began to believe that there might be some hope for the serial killer. Psychopathy wasn't treatable, but the paraphilia which Shiena forgot the name was. It wasn't the fact that she was potentially psychopathic that made her dangerous, since a lot of psychopaths were harmless. It was probably her sexual arousing for murder that was the primary cause of her sadistic behavior, but the fact that she lacked empathy and couldn't feel emotions normally certainly didn't help. If Shiena found a way to help Otoya with her sexual disorder, maybe she could eventually lose her sadistic impulses.

The brunette also began to think that Otoya's love for her might be more serious than she thought. After all, the serial killer murdered almost 30 women but she spared Shiena's life. She must felt something strong toward her to not act the way she normally do with girls. Otoya even displayed some genuine kindness toward. Shiena wondered if it was possible because she wasn't exactly her type. Maybe Otoya felt less sexual arousal toward her so she didn't feel the need to kill her. According to what she read lust murderers tend to not kill those who didn't fit their typical type of victims. Ironically, Shiena had to thank her plainness to have saved her life.

But even if Otoya truly loved her, what about Shiena? Could she possibly fall in love with the serial killer? Well, she couldn't deny that she felt a physical attraction toward Otoya. Shiena didn't want to admit it, but somehow Otoya's love for her made her feel good. She felt special because she didn't kill her unlike all of her victims. She didn't think it was really a positive thing to be special for a serial killer, but she couldn't deny that it made her happy. Maybe it was what true love was. You love someone because of how they made you feel. She may not be in love with Otoya for her personality, but she could develop some kind of love because of how she made her feel. It may sound selfish, but wasn't love in some way selfish?

"Well, I'll go take a shower." Shiena declared.

"Can I go with you!?" Otoya asked enthusiastically.

The brunette hesitated for a moment, before heading to the bathroom.

"…Do as you like." Shiena finally answered.

I'm not sure if Otoya is a psychopath, but she do fit the criteria. About erotophonophilia, I'm pretty sure she has it. It's litterally the sexual arousal of killing. It's kind of confirmed in the serie that it's the reason why she killed. But since I'm not a specialist, I may be wrong. The researches Shiena made were litteraly the reseaches I did myself, so if I'm wrong, Shiena could be wrong too, which wouldn't be an inconherence in this story since people can be wrong IRL too.
