First, I'm sorry for ooc Sei and Midorima. Second, It's not like I hate Himuro, but I just don't really care about this character, Sorry. And sorry for my English, if you will see some mistakes, please write them. It is seriously weird but I hope that it don't sucks as much as I think
~~~~~~~~~~~~~~~~~~~~~~~~~~~~

"You... Fucking bastard!!" snapped Midorima, while looking at Akashi as if he was something really disgusting "I never should agreed for her dating you, you... you..." "I order you to shut it, Shintarou, before I get mad at you. And you do not want it, am I right?" said Akashi, calmly continuing to play Shogi. "Right now I don't give a fuck if you're gonna kill me because I'll beat the hell out of you! I've forgiven you the first time you has hurt her but now I'm not going easy on you! How fucking dare you trying to threat me, you trash?!" Midorima was seriously pissed and even if Akashi was really eager to cut him with his scissors he stoped himself and asked: " What is your problem, Shintarou? And why you're cursing, it's not like you, right?" his eyes were glowing with insanity. GoM's number one shooter tried to calm down and he growled "How could you betrayed my sister, you bastard? She loved you, hell! She probably still does! And you has hurt her again. Why, Akashi? What did she does to deserve this kind of cruelty from you?" by now in his voice remained just sadness and resignation. " ...What are you talking about, Shintarou...?" he whispered, seriously shocked "Who told you this bullshit?!" For a while Midorima was just looking at him, not fully understanding the situation, but then his jaw landed on the floor. " Are you trying to tell me that you didn't..." he started but Akashi stoped him, shouting " There's no way I would harm my empress!!" his eyes were now only red and desperate, so there was no reason to not belive into his words. Midorima closed his eyes for a second and clenched fists. "The one, who said this... It was Himuro, Murasakibara's teammate. But why would he lie?". Dark aura started to surrond Seijuro, so Shintarou stepped back a little. "This fucking peasant" he growled furiously "He's trying to take my precious empress from me. I'll show him what I'm doing with motherfuckers like him!" he rushed to door and Midorima quickly went after him. Shintarou knew that Akashi was serious 'cause he hated this kind of language. In different place: Katrin was frantically running across park, hardly breathing, because of her asthma. But in this moment she couldn't care less. She has been informed that her boyfriend has been betraking her all along. She even saw photos, but she didn't want to talk with him about it or anything. She suddenly landed on hard ground, exhausted. She hugged her bruised knees to her chest, sobbing. Her fucking life was so hard and their relationship wasn't the easiest either. Akashi had splited personality and he got back to his good self just three months ago... She took out her inhaler from her bag but it happened to be empty. She knew what that meaned... After a short while she has lost consciousness. Then from behind the tree got out Himuro. He had smirk on his lips when he picked her up and carried somewhere. Akashi&Midorima: "Where the hell could she go?" asked Aomine. Akashi and Midorima called out the rest of GoM to find Katrin but after one hour of looking for her they still couldn't found her. It was getting darker and colder and all of them were tired, but not Seijuro. He was tumbling around the park, when others were coming back. "Does she has some kind of special place?" Riko asked, seriously worried, like everyone. "We've been there already" sighed Shintarou, trying to hold his cold attitude. Takao laid his hand on Shin's armii and ruffled his hair. "I belive we will find her, don't worry, Shin-chan" he smiled gently, but his smile wasn't true.He really cared for Shintarou and Katrin, plus she was their captain... "I have a last question..." started Akashi and his eyes landed on Murasakibara "Does Himuro has a summer house?" Everybody looked at him, suprised, when the giant nodded his head. "How did you...?" tried to ask Midorima, but Shintarou cutted him, waving his hand. " Later, Shintarou. Now.." " But I still can't belive that Tatsuya would do something like that!" shouted Kagami and Sei once again needed to restrain himself from killing someone. " Urusai, Kagami" he growled " I don't care what do you belive into, but it's fact that he lied to everyone about me and now Katrin disappeared. So I don't give a fuck if you think that he is oh so saint" He left them, going toward this fucker's summer house. (Don't ask how he knew the direction, it's Akashi, the absolute Emperor). Katrin's POV: I woke up, when I felt that someone was caressing my cheek. My eyes snapped open and I tried to sit up, but pain in my lungs was unbearable. "Shh, Katrin-chan..." said Himuro Tatsuya with a gentle smile on his face. He fished something out of his pocket and after a while I realized that it was an inhaler. "H-Himuro-kun..." my voice was hoarse "Can you..." He stopped me, putting the inhaler into my mouth and pressing. I inhaled deeply and then I felt so much better. Again I tried to sit only to find out that I'm handcuffed to the bedpost. "N-Na-Nani...? Himuro-kun...?" I looked at him but he still was smiling... "I don't want you to run away from me, Katrin-chan..." he leaned colder to me " I want you to love me, Katrin-chan... To look only at me... " his voice started to be threatening and in his eyes I saw madness. I turned my head away and said "Gomen ne, Himuro-kun... But I don't feel like you do... So would you let me go now...?" I was seriously getting scared... He smirked and caressed my chin with his finger, but then he squeezed it with too much strenght. "I can't, Katrin-chan... I want you all to myself... This worthless Akashi doesn't deserve you! You saw the pictures I send you, right?! He cares only for himself and his pleasure! You can't love him after this!" he was squashing my jaw. "Himuro-kun, ittai!" I whined but he leaned much closer, looking at my lips. "Say that you want me and only me. Say that you love me and I'll unchain you. Say it!" I really was scared but I wasn't going to lie. I shaked my head and then he took out a knife from his pocket. " So I'll kill you, Katrin-chan, because you only belong to me" he hissed and backed off "But first I'm going to tell you a story" his smile was wicked. "There was one boy who one day met really beautiful girl. He's fall in love with her at the very first time. They became friends but then he needed to go abroad and they lost their contact. After few years he was back but this beautiful woman found someone else, an wealthy bastard. He was treating her badly... The other boy knew that she deserved much better. So he faked evidences for betrayal, beliving that she will become his. And now, here we are... But not much longer" he lifted the knife above his head and seconds later it was in my stomach. I screamed in agony and after a while I passed out because of the pain. Akashi's POV: Quietly I came into Himuro's summer house. I was sure that he took my Empress here because I'm always right. While I was climbing up the stairs I heard an horrific scream. I beated down the door and then I saw my beautiful treasure, lying on white sheets, all covered in blood. Since this moment I don't remember much. All I've seen was crimson blood. Katrin's POV: I woke up at the found of beeping. I slowly opened my eyes, just to close them immediately because of the dazzling light. After a while I was ready to open them once more. I saw different kinds of machines around me and beside my bed, on the chair was sitting Seijuro. He was holding my hand, but his eyes were closed, probably sleeping. I remembered everything what happened and tears started to flow down my face. So he didn't betrayed me, that was all a lie... And if it would end, I would left him broken... I opened my mouth to speak but my voice wouldn't come out. I tried once more and this time it ended as a weak whisper: "Sei-chan..." it was all he needed to wake. I saw that his eyes were heterochromatic, but they were also swollen and red... He was crying... "I'm sorry, Katrin, I'm so sorry..." he hided his face in hands " If I came in faster... I would stop him" his voice was hoarse and shaking. "Seijuro, look at me" I said and when he did I smiled sadly "I'm sorry that I belived him. I should ask you about this, not ran away. It's not your fault, my beautiful Emperor, so don't say it's otherwise" He slowly stood up and leaned down to my face. He kissed my forehead and one tear has fallen on my face. "I don't want to lose you, my Empress. Without you it's impossible for me to survive. I want you as my wife as fast as it's possible. My father loves you and is positive about us as married couple. I love you, please, be my Queen forever" he kneeled down and took out small box. When he opened it I saw beautiful ring with big diamond, which he took and said: " Orihara Katrin, I order you to marry me and love me 'till the end of our days" "And I'll be very happy to oblige" I whispered, looking deeply into his eyes, which have changed to normal. He putted the ring on my finger and kissed me gently. "Rest, my beloved, you need to recover to play against us on Winter Cup" he smiled and patted her head, untill she fell asleep.
