You are fifteen.

Older by two years, he wasn't one to really express himself a lot, except for when he was being silly, goofing around or angered by his mentee's mistakes. Though he was a mafia executive, and even referred to as the 'demon prodigy' as you'd hear, you weren't ever quite afraid of him, he was your brother after all.

However, today's events sent an undeniably grim chill down your spine.

You'd been getting bullied by a group of boys in your school lately, who'd even make inappropriate comments about you. You didn't know what grade they were in, or what their names even were. All you knew, was that it utterly appalled you.

It wasn't until today when you fatefully forgot your lunch at home, and Dazai had to come to give it to you that he noticed and heard some of your male classmates discussing the things the older group had said about you earlier. Upon asking a few passing by, he heard you'd been sobbing in the bathroom. The fact that your situation disturbed you so much, yet you never told him, infuriated him greatly. But he wasn't just mad at you, he was mad at the boys who'd dared even think of you that way.

And so he dragged you by your wrist, pulling you out of the restrooms and to your classroom.

"Who were they." He questioned, his tone demanding as he glared at the classmates who'd been discussing the events. You tried to plead with him quietly, to calm him down, but he didn't budge.

"Oh, is the brother here to defend his baby sister?" One of your classmates teased. Dazai repeated his question, and upon their stubborn dismissal, he simply muttered a "wait here" before leaving through the door.

The next time he stepped back in, all the chatter in the room died out immediately. Every single student froze, as Dazai took slow, calculated steps towards the boy who was previously teasing him, his hand carrying an AK-47 against his shoulder. He looked him dead in the eye, his gaze lifeless.

"What. Are. The. Names."
