A/n : disclaimer I know how Krul Tepes dies in the anime but I'm going to change it for this story so I recommend watching the anime Owari no Seraph first before reading

Y/n p.o.v

I was walking throw Japan but not in my world, this world Grim Reaper was having trouble keeping up with the deaths because of Vampires or something so he asked me to take someone called Krul Tepes's soul but after reading her on my death book I told death I wish her to become a member of my peerage and he said it would be fine, so here i am walking throw japan looking for her.

3nd person p.o.v

a large battle was going on against the humans, and vampires but the queen of vampires was on the side with humans in order to protect Yuichiro Hyakuya and some vampires didn't like this so the revolt against her, as the battle went on Krul Tepes was battling a vampier when another one rushed her from behind

Mika : "Kurl look out!!!"

when she turned around her eyes widen as she see the vampire's blade about to cut her head off, but just then as its about to make contact something cuts the vampire's arms off making the sword fall to the ground

Vampier : "ahhhhhhhh!!!!"

everyone looks to see what it was and their eyes widen

Mika : "A scythe??"

they then face the way it came from to see a 16 year old boy with H/c and E/c, walking to them with a blank look on him as he got close something strange happened the humans black demon weapons started shaking like mad, just looking at the boy sent shivers down the vampire's back

Yu : "hey kid get out of here quickly"

but the boy still walked to them, just then some vampires ran at him, and he pulled out a sword and what he did shocked all of them.

when Y/n finished he made the sword disappear and held out his hand, the scythe that chopped the vampire's arms of came flying in to his hands, he stopped in the middle of the battle as both side looked at him waiting to see what he'll do he then started speaking

Y/n : "which 1 of you is Krul Tepes"

she then steps forward trying to show no fear but was failing

Krul : "t..that would be me why who are you"

Y/n : "me"

he then smiled and soon everyone felt a force unlike anything they have felt before, and soon Y/n was covered in flames again, when those flames died everyone looked in shocked to see Y/n in his reaper form

Y/n : "my name is Y/n L/n and I'm the grim reaper"

everyone started shaking like mad

Krul : "you mean its time"

Y/n : "yes please follow me Krul Tepes"

Krul : "no I can't"

Y/n : "and why not"

she then told Y/n everything from her brother to the 2 boys, Y/n just sighed

Y/n : "since I'm tired and can't deal with anything right now, if I get rid of them will you come peacefully"

she looks at the 2 boys and then back at Y/n

Krul : "yes" 

Y/n sighed and hit the bottom of his scythe of the ground which opened a portal, and the girls stepped out of it

(D/n, D/n2, Koneko, Ravel, Ophis, Ruby, Yang and Shinoa)

as they all stepped out this surprised them but the group of humans was most surprised about Shinoa stepping out of it

Yu : "Shinoa is that you"

she turned to them

Shinoa : "hey guys been a while"

Yu : "we thought you died"

Y/n : "Shinoa sorry but I need to girls to do something"

they all look at the vampires behind Y/n

D/n : "what do you want us to do"

Y/n : "kill all of them"

Timeskip

after the girls went in and wiped the floor with the vampier group, Y/n send them all home apart from Shinoa who was telling her friends what happened, while Y/n was talking to Krul Tepes

Y/n : "I have an offer for you"

Krul : "what's that"

Y/n : "I want you to join me and become my rook"

Y/n then tells her everything, and surprisingly  she agrees to become his rook, on the condition that she gets blood from him when ever she wants and since Y/n cant die he agreed, and made her his new rook, after both Krul and Shinoa said their goodbyes Y/n headed home with them when they did all the girls had their PJ's on since it was night and Shinoa left to put hers on as well and Krul looked confused

Krul : "what's going on"

Y/n : "the girls like sleeping with me for some reason"

just then Krul started blushing for some reason, when she did they other girls caught on and said she could join them, she turned to me and smirked a little before agreeing and left with the girls to my room

Y/n(mind) : "she's just in and she's going to sleep with me karma what did I do to you, I just want one night alone"
