Y/n p.o.v

I was in my room getting ready for my date with Yuuma, I finally got ready and walked to town I didn't want to take y car in case something happens to it, soon I got there and waited for Yuuma to show up as I was waiting this storage girl with 2 bat wings came to me and handed me a piece of paper

when she hands it to me she waves and leaves

Y/n(mind) : "why is no one questioning the way she looks"

I shrugged it off and looked at the paper

"You're Wish Will Be Granted"

Y/n(mind) : "my wish...what is this Dragon Ball Z"

i put the paper in my back pocket when I did I hear Yuuma

Yuuma : "hey Y/n"

I turned to her

Yuuma : "sorry I'm late did you wait long"

Y/n : "no I just got here"

Yuuma : "well shall we go"

Y/n : "sure"

Timeskip(End Of The Date)

3nd person p.o.v

As Y/n and Yuuma were walking through a park Yuuma turned to Y/n

Yuuma : "hey Y/n can I ask you something"

Y/n : "what's that"

Yuuma : "will you die for me"

this surprised Y/n

Y/n : "excuse me"

Yuuma : "I said will you die for me"

just then the sky changed and she started to change as well

Yuuma : "its been fun Y/n but this is where you die"

she then formed a light spear in her hand and through it at Y/n

Y/n p.o.v

after Yuuma change something appeared in her hand and then she through it at me, as it got closer and Closer you me I just sighed 

Y/n : "its a shame"

I then caught it before it hit my chest, i then took a closer look at it 

Y/n : "tell me what is this"

but when I looked at Yuuma she looked shocked

Yuuma : "what how can a weak human hold a light spear"

Y/n : "weak"

I then crushed it with little effort, when I did I started walking to her and she throw more of those Light spears at me but when they hit me they just shattered into pieces and then disappeared 

Y/n : "so Yuuma mind telling me who you really are"

Yuuma : "why when your about to die"

she then made another one but this time she ran at me and tired to stab me, but I grabbed her arm and started squeezing until I heard a snap, yuuma then started screaming in pain

Yuuma : "ahhh!!!!"

I then let her go and she backs up holding her arm, I then used my speed to appear in front of her, when I did she looked at me in shock

Y/n : "I'm running out of mercy with you Yuuma"

Yuuma : "w..what do you want"

Y/n : "I wont kill you sorry but that's not how I was taught but if I see you again you wont walk away on your own 2 feet understand"

she nods and fly's off, I then turned to a bush

Y/n : "you can come out now I know your there"

I then see the same white haired girl that's been following me walk out the bush

Y/n : "why have you been following me"

she looked shocked

Koneko : "you knew"

Y/n : "yes I did now answer my question"

??? : "I sent her to look out for you"

I turned around to see a group of people standing there

Y/n : "and you are"

Rias : "my name is Rias Gremory and this is my peerage Akeno, Kiba, Koneko and Issei"

Y/n : "so why are you here"

Rias : "we wanted to make sure you were unharmed"

I used my super hearing to hear her heart beat faster

Y/n : "your full of shit"

they go wide eyed 

Rias : "what"

Y/n : "I said your full of shit I can hear your heart beat faster which means your lying to me"

just then she looks at the blonde one called Kiba and nods he then uses his speed to get to the side of me and uses his sword to try and stab me, but I just smirked

Y/n : "you call that speed"

he's eyes widen but it was to late I already had him by the neck, I then slammed him into the ground knocking him out, I then left his body on the ground I then looked at Rias and the rest of them who looked shocked

Y/n : "is that all you have"

just then I hear something 

Boost

I turned to see Issei running at my with some weird red gauntlet, I simply caught it with my left hand 

Y/n : "wow was that it"

I then started crushing it which caused Issei to scream in pain, i didn't get it I wasn't even putting any power behind it but soon everyone heard a crack, I looked down to see Issei's gauntlet had a large crack going down it now, I then see that his hand is bleeding as well now so I let go and he falls back holding his hand, as they checked on both Issei and Kiba I stood in front of them 

Y/n : "if I ever catch you following me again Gremory next time I wont be so nice"

I then crouched and took off leaving a creator as well as a sonic boom behind me and headed home

Rias p.o.v

I could believe what just happened first he takes out a fallen, then knocks out Kiba but what shocked me the most is now the boosted gear is cracked

Issei : "I'm sorry prez"

Rias : "no you did fine"

I then told Akeno to take Issei home and Koneko to take Kiba, while I headed to the ORC building to think about what I just saw and how to deal with it 

Rias(mind) : "where did that power come from no human could of done what he did hell most devils couldn't of beat Kiba in a test of speed, then there's the boosted gear no one should be able to do that Y/n...just what are you"
