Yuuki looked quietly at the interaction between two sisters while sitting on his personal chair. He read a book quietly while ignoring her.


    "HMMPHHHMM!!!!" Akeno was moving like a lobster to throw off this hateful guy.


    "Hey, don''t move around, I can''t read in peace," Yuuki said with an annoying tone.


    "HMMPHH!!!!" Akeno became very angry at him.


    Yuuki sighed and closed his book. He looked at her and said, "I''ll take the towel in your mouth but you can''t scream okay?"


    "HMMPHHH!!!" Akeno ignored him.


    "Then, I won''t take off the towel," Yuuki decided to continue to read a book until he saw her nodding at him. He looked at her and smiled, "Good, girl." He took off the towel in her mouth.


    "Aahh, you bas-," before Akeno finished her words, she was being gagged again.


    "Don''t scream, okay?" Akeno nodded in response with an angry expression.


    "Good," Yuuki nodded and took it off.


    "Who are you?" Akeno asked him. She needed to confirm whether he was an enemy or not.


    "Me? I''m just an S that likes to tease an M like you," his tone was very deep and entered deep into her soul.


    Akeno shuddered and blushed but she wasn''t just M. She was also an S and her pride wouldn''t allow her to be dominated by this strange guy.


    "Answer me, seriously!" Akeno looked very angry.


    "Well, I''m just helping her to meet her sister, that''s all if you want to know if I''m an enemy or not, then you should be able to guess, I can kill you easily after all since I can subdue you in seconds," Yuuki opened his book and read it.


    Even though Akeno felt bitter but she knew what he said was right. She knew that this guy could kill them easily without effort and this made her feel very worried. There was someone who could enter their territory without anyone noticing and strong enough to subdue her in seconds. She needed to call Rias and everyone.


    "Ah, I forgot to say that, you can''t use your magic now, that rope is special and you can''t call your master, don''t do anything okay? I just want to tend to the rtionship between sisters," Yuuki said while reading a book.


    Akeno raised her eyebrows and said, "Tend the rtionship between sisters? Do you know what she had done to Koneko? She abandoned her and ran away by herself after she killed her master! If it was not because of Rias, then Koneko wouldn''t be able to live right now!!"


    Yuuki sighed and closed the book, "That''s true, but Kuroka also has her own reason to do that."


    "HAAA?? WHAT KIND OF REASON? ABANDON IS ABANDON! THERE IS NO REASON!!" Akeno was agitated.


    Yuuki looked at her weirdly and said, "What is it? Why are you strangely angry about it? Do you have the same experience as her? Did someone abandon you too?" He knew what Akeno had gone through but he needed to act as if he didn''t know anything.


    Akeno flinched and looked away from him.


    "Hmm, so you also have the experience of being abandoned," Yuuki said.


    "It''s not your business!" Akeno shouted.


    "Well, that''s true, it''s not my business, but I''m curious, why did someone abandon such a cute girl like you? And who abandons you? Your siblings? No, then your parents?"


    Akeno flinched at his words.


    "Hmm, your parents, then who is it? Is it your mother? No, I guess, then your father, right?"


    "Shut up!!" Akeno shouted.


    "Well, what happens? Is it your father, did he really abandon you? Or does he have some problem and it makes him look like he abandoned you?" Yuuki said.


    Akeno was silent and didn''t say anything. She started to think about what he said to her.


    "Anyway, it seems you''re quite envious about the rtionship between Shirone and Kuroka, how about it? Do you want me to help you to tend to the rtionship between you and your father?" Yuuki asked.


    "You know what, you''re very annoying," Akeno told him.


    "Really? Then, I really seed in making you annoyed."


    "YOU!!!" Akeno was angry and sighed. She didn''t know why but she felt very angry whenever she met him. She always thought about this masked man and couldn''t focus on her job as a devil. She had thought of several ns to beat this guy but he defeated her easily. He also knew about how she hated her father. She was also quite envious of Koneko who was able to tend her rtionship with her sister.


    "Hey, your name is Akeno, right?" Yuuki asked.


    "What do you want?" Akeno looked at him suspiciously.


    "Do you want to go with me?" Yuuki asked.


    "What? Are you crazy? You''re my enemy! An enemy! Do you think, I''ll go with you?" Akeno looked at him as if someone was crazy. She looked at him and could see the smile under his mask.


    "It''s not that good that I''m your enemy since you''re a big masochist, you''ll feel happy following your enemy," Yuuki teased.


    "YOU!!!" Akeno was angry and wanted to bite this guy to death.


    "Well, I''m teasing you, I know you won''t follow me," Yuuki took his book and continued to read it.


    Akeno also didn''t say anything and looked away.


    Neither of them said anything until Kuroka came to him.


    "ZERO!! KONEKO, DIDN''T BELIEVE THAT YOU CAN SING, NYAA!!!" Kuroka clung to him and looked like very hurt.


    Yuuki closed his book and sighed, "Then do you want me to sing for you?"


    Kuroka nodded, "Give me the romantic song, that you can sing for me, nyaa! Show my sister that you can sing and love me very much, nyaaa!"


    "I''m not dating you yet," Yuuki said.


    "But, didn''t you say, you want my heart? You want it right? You want to mate with me, nyaa!! Sing me some song, nyaa!!" Kuroka shook his body very hard.


    "I get it! I get it! I''ll sing it for you!" Yuuki said.


    "Good, nyaa!" Kuroka seemed satisfied and sat while resting on his body. She didn''t care that he was sitting on the top of Akeno since she knew this girl was a masochist.


    Koneko looked at him curiously but with some doubt as well.


    Akeno tried to ignore them but also listened as well.


    Yuuki made a guitar out of nothing and said, "This song title is ''Hyakunen no Koi''."


    "A hundred-year love, wow, hurry up!!" Kuroka was excited.


    Koneko and Akeno also looked at him with amazement since this song title was very romantic. But they were still doubting him.


    "Ahem, then, I''ll start," Yuuki started ying his guitar.
