Here is a clear reason why not to anger me.

After a eventful night both Koneko and Yuno was walking to school together. They drew the attention of everyone there.

RB1:"Damn it don't tell me he took Koneko to?" he said with tears in his eyes.

RB2:"At this rate we are never going to get laid."

RG1:"They are so cute, but I bet it'll be better with me."

multiple RG's:"NO ME"

Yuno:" Whare you all so loud?" he asked a random girl

RG:"oh we're wondering if Koneko is your girlfriend?" she said nervously.

Yuno:"Well yeah she is my girlfriend sonis all the girls." he said giving a idoit smile making all the girls blush.

Acnologia:3...2....1...

ALL BOY: "MOTHERF#CKER" they shouted alerting the entire school.

Yuno:"So loud" he said covering his ears.

The day ended with Yuno getting glares from the boys. He along with his best buddy and Koko were walking to the ORC club.

As they got there Akeno was talking to Kiba as Rias eas comong out the shower.

Yuno:"You must have a weird fetish with showers huh mighty tomato" he said with a smirk.

Rias:"I'm don't want to be hearing that from you" she said angrily.

Yuno:"So your not denying it"

Rias just groaned in frustration before moving on.

Rias:"Okay moving on Yuno and Issei for the next few days you will be handing put flyers and doing summons."

Time Skip because I don't feel like it.

Yuno finished handing out his flyers. It was easy for him since he was handsome and most women gave him some numbers. In less then an hour he finished leaving Issei alone.

Yuno*I would feel bad leaving him alone like that, but he needs to do things on his own.* he said giving Issei a prayer.

As Yuno was walking home he smelled blood. Knowing that it was coming for a warehouse. He walked there while summpning a barrier around the area. He sensed a stray there.

Entering he saw everywhere waa blood and skeletons. Angered his black eyes glowed crimson red.

Stray: "I smell something and smells tasty." A women appeared naked playong with her breast, but her lower half was hidden in darkness.

Stray:"Why not come over here little boy and I can give you a good time."

Yuno:"No and why did you kill these humans?" he said in a monotone voice as his hair was covering his eyes.

The stray didn't notice, but Yuno was clearly pissed. A stupid pathetic Devil killed innocent humans for what.

Stray:"Because I wanted to and its fun" she said beginning to laugh only to fall on the ground. Her lower half was gone. She didn't even see what happen.

As soon as Yuno heard her reason he snapped. The leaders of the 3 factions would have only seen a slight blur, but the ones at the pinnacle of power would shit themselves. It happened in less than a second. It was as if time slowed down for Yuno. He walked up to the stray and used his aura to form a bladed. He perfectly cut the stray from her monstrous body before slashing away at the lower half in to millions of pieces.

The stray looked at the boy above her and she wish she didn't. The look on his face was emotionless as if he was doing a chore, but his eyes were glowing crimson red. They swirled like a never ending vortex.

Yuno:"So you killed these innocent people for fun, then I guess you won't mind dying then." he said as he dropped the barrier surrounding the building before summoning another special barrier around the two. The barrier is something he spent years making a resurrection barrier. Anything that dies while inside would be revived in 3 seconds perfectly restored.

Yuno:"For playing with the lives of others you shall die a thousand deaths mongrel" he then shatter her into a bloody mess.

She was revived in three seconds. As she wondered what happened Yuno grabbed her by the neckand proceeded to slowly crush her neck while she stared back. Her fight or flight instincts kicked and she desperately tried to claw at his face do anything to keep living, but it was all effortless. Yuno placed aura protected him. Only devils of high rank have any hope of putting a paper thin scratch on him.

Slowly the stray felt and heard her neck break. In five minutes her neck finally broke killing her.

Sh was once again revived. She was crying begging for mercy for anyone to save her even her old master.

Yuno:"You've brought this on yourself your actions have consequences be glad I've decided to speed this up.

For one hour the stray died a thousand gruesome deaths as Yuno promised. He dropped the barrier and summoned his sacred gear. He placed his palm in front of the stray whose eyes were lifeless.

Yuno:"Hakai" he said and the stray disappeared onto purple particles.

Finally calmned down he decided to leave as he left he ran into Rias and her peerage.

Rias:"What are you doing here?" she asked him in her annoying prideful tone.

Yuno:"Killing a stray and you need to take better care of your "territory". Also I'm leaving clean up to you" he said as he began walking away.

The group didn't stop him because he was giving off a don't talk to me aura or you'll regret it.

Everyone*What could possibly piss him off.* they all thought before looking in the warehouse.
