After getting back home Sunny took the info from BW and sent it to Doktor who was in a video chat now, but it wasn't just Doktor in the call Boris, Courtney, Kevin and even Raiden was in the call, after playing the recording that BW took of Y/n interrogating Kiba the looked on everyone was shock

Doktor : "incredible so magic does exist"

Radian : "so the Metal Gears can use magic now"

Kevin : "how to you beat something with magic"

Y/n : "the Murasama cut through it just fine"

Doktor : "I see the Metal Gears must have a magic barrier around them stopping any magic attacks from doing anything, but since your blade has no magic in it the barrier didn't stop it"

Courtney : "but how will Y/n fight against devils, angels and Fallen angels then"

After thinking for a bit 

Doktor : "I got it, Y/n that boy you question he mentioned something about stray devils"

Y/n :"yeah a stray Devil is a devil who have diverted away from their masters for their own selfish desires"

Doktor : "I see Y/n, if you could bring me a sample of one I could use its DNA and perhaps create something for you to use against the factions"

Y/n : "on it I'll head out the now"

Y/n and BW leave and go on a hunt for a stray devil

Timeskip(3rd Person P.O.V)

After walking around for a bit Y/n found a warehouse when he entered it he looked around to see it was empty, sighing he turned around to leave but

??? : "well what do we have here"

Y/n turned around to see a girl smiling at him

Y/n : "and you are"

Viser : "call me Viser sweetheart"

Y/n : "so tell me you wouldn't happen to be a stray devil would you"

Viser : "oh and what if I am cutie"

Y/n : "well if you are then"

just then Y/n sliced both her arms clean off and cut them into pieces Viser's eyes widen and she soon screamed in pain

Viser : "YOU BASTERED I'LL..."

Just then Y/n sliced the upper half of her body clean off as she laid there Y/n walked to her and picked her up by the neck

Viser : "w..what are you"

Y/n : "Kiba was right, Devils really are durable"

Viser : "p..please let m..me go"

Y/n : "let me think"

Y/n punched a hole right through Viser's chest ripping her heart out

Y/n : "no"

Y/n pulled his hand from Viser's chest with her heart in his hand as BW took some blood from Viser's corpse Y/n looked at the heart before crushing it in his hands

Small Timeskip

After BW collected the blood that Doktor wanted they were about to leave when they heard a familer voice

Rias : "stop"

Y/n(mind) : "for fuck sake"

Y/n turned to see Rias and her peerage along with a few others

Y/n : "what do you want"

Rias : "did you kill her"

Y/n : "no we had a tea party"

Rias : "I demand to know who you are"

Y/n : "isn't that a shame we all dont get what we want"

as Y/n and BW began leaving

Welsh Dragon Over Booster

Y/n turned to see Issei in red armour 

Issei : "your not leaving this time"

Y/n : "oh and who's going to stop me"

Issei : "Ddriag ready"

Ddriag : "always partner"

As Issei got ready to fight Y/n saw Rias and her group smiling and smirking all while Y/n just looked like he didn't care, just then Issei with a burst of speed charged and Y/n but what happened next shocked everyone Y/n cut Issei's arm clean off and he was thrown out his armour as he started screaming in pain

All(apart from Y/n and BW) : "ISSEI"

all of them were about to run to him but stopped when they saw Y/n's sword aiming for ISsei's neck

Y/n : "move one inch and I'll kill him"

As Issei was crying Y/n grabbed him but his neck and picked him off the ground and brought him to his face

Y/n : "so you were going to stop me from leaving, was this all you had"

Issei : "I...I"

Y/n : "I dont care, if you try that again Hyoudou I'll take your head off next time"

Issei nods and Y/n throws him away but has he was about to leave he notices Issei's dragon blood on the ground and smile

Y/n : "BW take some of the dragon blood while we're at it"

BW did that and they left leaving the group to heal Issei's wounds but what o one saw was a familer bird watched the whole thing and its master was smiling at what he had just seen

??? : "girls we will have revenge on the Red Dragon Emperor"

All(Girls) : "yes King Riser...."
