Second chapter! Thanks for the reviews, favs and follows, you encourage me! :)

No mature content in this chapter, but the next one yes.

Shiena looked at her former roommate in shock. She didn't expect to see her again. In fact, the brunette was scared to see her here. Otoya was a sadistic bully, with a lack of empathy, exactly the kind of person Shiena hated the most. She was also a serial killer, it was worrying to know that such a dangerous girl knew her address.

"What are you doing here?" Otoya seriously asked.

"What am I doing here?" I'm living here idiot! The real question is, what are you doing in front of my apartment? And how did you get my address?

"It's your apartment, really? Cool!"

Without Shiena's permission, Otoya entered the apartment, which annoyed its owner.

"Wow, you have a nice apartment!" Otoya said. "You're living alone, at your age? Is this legal?"

"Just shut up and get out of my apartment!" Shiena angrily screamed.

"Why are you so mean with me? You're making me sad…"

Shiena didn't know how to react. Otoya was trying to mess with her, but she seemed to be sad for real.

"Don't pay attention to her." Shiena thought. "She's just a bully who tries to manipulate you."

The dark haired assassin continued to inspect the apartment.

"You have so many books Shiena-chan! Are you some kind of nerd? How cute! Oh, you even have manga…"

"Go to hell! And don't call me cute, idiot!"

"What kinds of manga do you read? Hentai? Ecchi? You look like a girl who would read yaoi…"

"Absolutely not!" Shiena protested.

"Really? So, maybe you read yuri…"

" …no…"

While Otoya was looking at the manga, Shiena noticed her prison uniform.

"You escaped from prison don't you?" Shiena asked.

"Yes."

"How?"

"A prison guard freed me, I don't know why. Oh, and he gave me your address."

"What!? Wait, why did he give you my address?"

"I don't know. That's not important, what matters is that I've found you."

Suddenly, Otoya gave Shiena a hug. She blushed, embarrassed, but she did not break it.

"I like you, Shiena-chan."

"What did you say? You're lying! You're just a bully who tries to mess with my feelings…"

It was Otoya who broke the hug. She seemed to be upset by what Shiena had just said.

"You're the one who's messing with my feelings right now." Otoya sadly said.

Shiena didn't understand what was happening. Did she really hurt Otoya?

"No, I don't." Shiena thought. "She is just trying to manipulate me…"

Otoya, with a sad expression, walked towards the exit door. Shiena began to feel uncomfortable.

"Wait, Takechi-san!" Shiena said. "I don't know if you are sincere, but I'm sorry if I hurt your feelings…"

The dark haired assassin stopped, back to Shiena. An evil smile appeared on her face. When she turned to the brunette, Otoya showed a fake friendly smile. Of course, she really liked Shiena, but not like a normal person did. She liked her in her sadistic way, she wanted to make her suffer, to torment her, to torture her, to make her cry and beg for mercy, to make her bleed, to have her way with her. But strangely, Otoya didn't want to kill her.

"Can I stay for the night?" Otoya asked.

"No."

"Please, Shiena-chan! I have nowhere to go and I have the police on my trail."

"Why should I help a serial killer who killed innocent people?"

"You're an assassin too!"

"Yeah, but I only killed bad people. In fact, I kill people like you. Do you really want to stay with someone who can kill you in your sleep?"

"If this someone is you, yes." Otoya answered.

This answer made Shiena blush again. For an unknown reason, she didn't dislike being with Otoya, even if she was a bully, the kind of person she hated the most.

"Ok, you can stay. But just for one night, got it?"

"Yes! Thank you, Shiena-chan!"

Again, Otoya gave Shiena an affectionate hug, which embarrassed the brunette, like the first one.

It was the middle of the night. Otoya was sleeping on the couch, in the living room. Shiena was awake. The brunette approached the sleeping assassin, a knife in her hand.

"I can't let her live." Shiena thought. "She's too dangerous, she going to kill other innocent people. I must kill her."

Her hand began to shake. She was nervous.

"I can't have pity for her. She's a bully and a serial killer. She's even worse than all the people I've killed."

Shiena still hesitated to kill Otoya.

"She's sleeping, she will not even suffer, so I need to kill her now!"

She raised her knife, but couldn't do it. The brunette threw her weapon on the floor.

"I can't kill her" Shiena said. "It would be unfair, killing someone who's sleeping. I would be a coward."

Shiena started walking towards her bedroom.

"You really are a good person, Shiena-chan. How cute."

Without warning, the dark haired assassin punched her in the face. Shiena fell on the floor, with blood dripping from her lip. Otoya took the knife, while the brunette was trying to stand up. The serial kill attacked her with the knife, inflicting her a slight cut on the right cheek. Blood came out, and Shiena let out a cry of pain. Otoya kicked her in the stomach, which knocked her on the floor. Otoya sat on Shiena, put her hands around her neck and began to strangle the brunette. She tried to break free from the killer, in vain. Due to the lack of oxygen, she lost consciousness. Otoya released her and stood up. A smirk appeared on her face. The serial killer sought a particular object in the apartment. She smiled when she found it. It…a pair of scissors. She looked at Shiena with lust, licking the scissors' blade.

Nio was in front of the chairwoman, Yuri Meichi, with a grin on her face.

"I understand now." Meichi said, neutral. "You have freed Takechi-san from prison, and have given her Kenmochi-san's address. How cruel, do you want Kenmochi-san to have an horrible death?"

"Well, she tried to hack our network system and expose Myojo Academy secrets. Of course, I could use a normal assassin to kill her, but it would be less funny, don't you think?"

Meichi smiled.

"You're sadistic, Nio-san."

"Maybe you're right."

Nio approached the chairwoman and sat on her knees.

"I won't let anyone bother you." Nio seriously added.

Meichi gently patted Nio's head. The blonde assassin snuggled in the chairwoman arms, before falling asleep.
