【 Thanking Betrayal 】 Yandere Dazai x reader

➢ Prologue

Being the Port Mafia's boss was always an entertaining occupation, the splatter of blood, the control, the expected respect. Mori loved it. He always walked around the halls, black coat glittered with the light traces of death, of blood. But also, there was the trickery. The difficulties in leading such a mass of an organization, the constant weight of assassination and death above his head, and trying to deceive right and take away wrong. Telling right from wrong was the exact predicament Mori had to face during that day. He sat in his office, fingers intertwined, connecting his hands where he placed his chin. Calmly, he was always calm. Whether it was faked, apathy, psychotic, or true calmness, Mori never showcased fear. Control over emotions was a superior trait as a mafia member. As he sat, the phone stood still, though its sudden call vibrated his table lightly; catching his attention. His gloved hands took the phone. 

"Mori." Despite the lack of information, he knew who this was. The voice was desperate, vulnerable, something the person calling never was. It was an odd day, perhaps a good day for the boss. "This is quite the predicament, I'd never thought I'd hear that voice of yours for desperate." Mori pointed out, fully showing his intent to how he knew the other was at his mercy. "My organization has been captured, only 5 of us are alive." Eyes widened, there was a silence met in their conversation as Mori tried comprehending the information. Truly, this was something new. Without reply, the voice was holding back frantics, trying to remain calm as it continued to explain: "We're being hunted by the Military's Special Ability Unit. In 20 minutes Heila's ability will be hackneyed and enervated, we can't fight against them forever. They're sending the Hunting Dogs, and once they get here, the [l/n] family will be no longer."

"You want me to save you, then?" Mori asked, exhaling a breath as though his surprise from earlier left with it. "There is no way you can save all of us. If we do manage to survive, we will live underground, the hunting dogs will not cease their mission until every one of us is eliminated. That is a tiring life that none of us wish to live. One of our family members has committed no crime, but will be executed by the Hunting Dogs once as they are with us and will be confused as an accomplice." Mori smiled, death was something he experienced daily. Normally, even experiencing death directly or indirectly was mentally devastating. But humans can become desensitized to the most brutal of things if they see it enough. "Suicide, then? You didn't cross me as the type. So, I should only save this person? What exactly is the benefit for me?" 

"Officially, she does not exist. This makes her to be a great ally in terms of crime. She also has an ability." "Are you suggesting I use her to work for me?" Mori reaffirmed. "..Yes. But, although there may not be a benefit, I do hope you refrain from abusing her. One day, she will realize the deal you've made with me today, she will realize her family's past. It is wise to treat her well like your own."  Mori pondered for a moment, seconds passed and his eyes closed, when he exhaled and opened them, a smile spread across his lips. "I was teasing, promise. I will cause her no harm." Mori smiled, his voice hinted with a forced sly of positivity.
     "I will save her."

Your body felt heavy, your mind felt numb. Tired, you're tired. The burn of the light from the crack of the door taunted you, it taunted your exhausted state and warmed your cold skin that contrasted the metallic floor. Wet, what is that? You wondered, your palm glided along the floor as you sat up, you brought your fingertips back to you. Red, why is it... You cut yourself off, a gasp of air-filled your throat like a mantra. Your head whipped around the room, your family's dead bodies faced back. Your eyes so wide they felt cold against the air. Silent tears streams from the inner corners of your eyes, you made no sound. No sound apart from the dripping of blood and your tears against the floor. Your skin itched from the stream and a touch of tears, you wiped your face. You stood up, your brain seeing everything you didn't want to see; your brain absorbed every detail it wanted to forget. Your eyes met the one of your most loved ones, theirs were dull, loss of light, loss of life. They were a rag doll, the brutal deceased shell oozing of blood that used to be the one you spoke, played and interacted with. You wanted to look away, but you wanted to take in the sight.
