????: any of Freed's and Diodora's freaks attacked you?

Rin: none of them attacked us.

????: Honkais? Same thing as those two?

Mashu: same with Freed and Diodora.

????: Good, Saber how's your Alter doing?

Saber: she's doing good, she said she misses you.

????: yeah, she's a good woman and I respect that. Jeanne'D Arc anything interesting?

Jeann: Honkais were taken down by the Valkyries.

????: after 3 years they've gotten stronger but I'm stronger than them, okay i'll be with my sister so keep the place safe.

Mashu: yes bye Y/n!!

(Meanwhile with Rias)

Rias:*huff* you still want be forgiven by Y/n!?

Kiana: yes we've regret our actions to him!!

Y/n: Tch!! More than begging!!

Rias: brother!!

The city was in ruins luckily many people escaped. The Valkyries, Rias's peerage and Y/n felt the dark energy from Honkais. Y/n takes out two handguns. He heard growls from Assukas and three Parvatis.

Y/n:....

They charged at him but Y/n shot them with bullets very fast in a perfect formations that a certain kid who has OCD problems would be proud.

Y/n:....

He takes out his phone and his A.I speaks.

A.I: Nevan downloading 100% complete.

His handguns turned into guitar, lightning sparks around it.

Y/n:.....

He rushes at them it transform into a scythe. The blade hits the head of a Assuka and he rushes to the other Honkais.

Y/n:......

He stabs a Parvati and a electric current shocked the Assukas paralyzing them in the aura. He starts to silce each Honkai, slicing them so they are dead.

Y/n:*growls*
(Meanwhile at St. Freya Academy)

Otto: Y/n!?

Venelana: he's my son Otto.

Otto: he's your son!?

Zeoticus: yes he's my step-son.

Otto:*gulps* I see

Sirzech: and you'll be watching him fighting and understand to never mess with a Gremory.

Otto: the G..Gremory clan!?

(Meanwhile back to the city)
He kept slicing them, beating them down to the ground showing the Valkyries the brutality to any Honkai. He charges up his demonic energy and an A.I speaks.

[There should be a GIF or video here. Update the app now to see it.]

A.I: Devil Trigger 100% complete.

He growls and screams in pain. His body turned into a red demon body as everything changed in him.

Y/n:*screams*

He flies to the Shadow Knight and shot them with his smoke powers. His weapon transform into a blade known for it's wielder even Sirin would fear him and his family.

(Back to St. Freya Academy)

Venelana: that form, very powerful.

Sirzech: his devil trigger if i can remember correctly.

Otto: what is a devil trigger?

Venelana: devil trigger is only used if anyone who is a demon, hybrid or somebody who is cursed or somehow connected to any demons and devils. Their overall experience would increase causing them to be very dangerous. They become cold and aggressive to any enemies in their path. To harm them is the use of light or angel powers but people mistaken them as evil beings but some demons and devils are not even evil at all. Due to Y/n been a half of an Archangel from his father, it's nothing but child's play.

Otto: oh fuck.

Zeoticus: you fucked up.

(Back with them)

Rias uses her demonic energy to create a shield to protect Y/n as he charges up for the Blue Flames Form.

Y/n: HAAAAAAAAAAAA!! LET THE DEVIL'S TEARS BURN IN MY SOUL!!!

(Anular and Iblis)

Then more enemies arrived but they were  zombie girls which Y/n didn't real expected and finds them cute.
(Zoey)

(Archer)

(Scythe)

(Nina)

(Fiona)

(Sarah)

(Valerie)

They all charged at him but he runs up the buildings and jumped over them as he winks at them. They blushed but got kicked by the back as he uses Galactic Donuts to hold them down.

Y/n: Gunslinger: Rainstorm!!!

He jumps on top of the Assukas and shot barrages of bullets rapidly.

Y/n: Trickster!!!

He teleports to the nearest Parvatis, grabs the horns and slams it to the ground while the other two Parvatis but uses RoyalGuard to one kill them.

Y/n: DIE!!!

He slices the last Honkai in half. Pink blood drips from his sword as he transforms back to normal while a girl around his age arrives.

Y/n: Eydis any injures?

Eydis: yes some were server but we're able to heal them back to health.

Y/n: good just need finish the job and relax.

Eydis: what should we do with the zombie girls?

Y/n: take them in. They can be our new allies.

Eydis: yes Y/n.

She teleports them to the Y/n's base as Y/n hugs Rias and her peerage.

Y/n: nice to see you strong as ever Rias, same with the rest of your peerage.

Rias: thank you brother.

Mei: brother!?

Y/n: well looks like you haven't slack off. That's good because I can beat you four bitches to the ground bloody and bruised.

Kiana: Y/n we're sorry what we did!!

Y/n: beg all you want that won't fix the mess you four made 3 years ago!!

He flies back to his base while Rias's peerage follows him.

Sin:*mind* my heart feels....broken....
