Y/n:*meditating*

Ann: Y/n...

Y/n: since when did you get in my training arena?

Ann: door was unlocked and they're here.

Y/n:*sigh* so you know it now?

Yukari:💢 oh yes since you had sex with Ann.

Sumire: actually he had sex with Ann, then myself and Gobi.

Yusuke: you did what!?

Y/n:*sweats in fear*

Asia:*blush*

Akeno: ara, ara, Y/n~ you got some guts to have sex with three girls.

Y/n:*muffed screams*

Ryuji: wait just let him go he had enough.

Shadow Y/n: awww how cute, my counter part is getting loved by his harem.

Y/n: shut up!!

Asuna: who's there!?

Shadow Y/n: baby come on it's me!! Your lovely boyfriend*giggles* shame you were dead along with the others!!

Then everyone smell a scent of blood coming from Y/n's shadow.

Ryuji: is that blood!?

Shadow Y/n: oops I made a bloody mess because I killed, your uncle, Sojiro and Wakaba!!

Futaba: y-y-you killed my family!!

Shadow Y/n: grow up you little shit!! They're were going to die by fallen angels anyway!!

Y/n: you...

Shadow Y/n: awwww did I hit a heart? I can hear their screams of pain. They're begging was perfection at it's finest. It was listen to music. The fountain of sorrow, I like the way the bloodiness feels against my skin...

Makoto: you monster!!

Y/n: YOU SON OF A BITCH!!!

Y/n: I'LL MAKE YOUR OWN SOUL A LIVING HELL!!

Shadow Y/n: yes!! That's right let your anger consume you!! WE'RE BOTH THE SAME!! WE LOST OUR FAMILIES, PEOPLE WE HAVE CONNECTIONS WITH, RISK THEM THAT WE HAVE TO DO TO ACHIEVE POWER!! YOU'RE ME!! I'M YOU!!

Y/n: YOU'RE NOT ME!!

Then he began to chant.

Y/n: I, Y/n shall bring judgement and chaos of those who harms my home. Oh Bahamut lend me your energy!! Lend me  your power to protect the people who I love to my dear soul!!

Shadow Y/n: no!! You shouldn't awaken juggernaut mode!!

Y/n: feel the power of SPARDA!!

He takes out Devil Sword Dante and did a Billion Stab finishing with Devil Strike.

Shadow Y/n: dam!! This will get ugly!!

Y/n: get back here!!

He takes out his arms and shot barrages of bullets piercing his body and summons a group of Thrashers which used their roots to grab his shadow's body and rip him apart.

Shadow Y/n: d-dam you!!

Y/n: get out or suffer like what you did to my family!!

Shadow Y/n:*smirks* sure but here's a warning. YVHV and Yaldabaoth will become on being. A true form of god and you will be guided by his will both humanity and demons like.

Rias:!!!!

Then he vanishes as Y/n transforms back to normal. He was his knees as tears flown out his eyes as he screams.

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

Y/n: EEEEHHHHHHHAAAAAAAAAA!!

Clouds formed as rain fell, Y/n cried. He slams his hands on the ground.

Y/n: everything I did to protect!! Now gone!!*sobs* I lost them!! Why!? They didn't nothing wrong!! It should've been me, not them!!

Then Nyx and Izanami arrived. Izanami reveals that Nanoko was safe but has some damage on her body. He began to twitch as his friends began to worried.

Ann: Y/n, what's wrong!?

Then his heart began to beat faster and faster as the screen shows chains holding him down but snapped as black aura surrounds him. Everyone fell to the ground as the aura revealing Y/n but as Thanatos.

Nyx: Thanatos!?

Y/n:*hollow scream*

Eugeo, Akechi, Sachi, Yuna, Yuuki, Aether and everyone Y/n has been dating taken out their weapons and blocked his attacks.

Alechi: Y/n, snap out of it!!

Y/n:*screams*

He grabbed his "head" ripping apart the "body", which caused him go back to normal. He summons Thanatos card and Orpheus card, smashes both cards and fused into one card, which is the Messiah card and he summons him along with Izanagi, Magatsu and Arsene.

Y/n: PERSONA!!!

Messiah: I am thou, thou art I. I'am Messiah. From here forward, I shall exist together with you...

Y/n dropped to his knees as he cried. He looks up to Messiah, Izanagi, Magatsu and Arsene.

Y/n: what have I do wrong? Tell me!!

Izanagi: forgive me Y/n, even to my own powers and Izanami's powers. YHVH's is to strong.
(Saying YHVH's name is too holy so don't say it or die from him)

Messiah: even if I had aid from my fellow angels, YHVH would break us all.

Magatsu: even with our current power even with Juggernaut's power boost, we're still not strong. We need help from other people who have been into more serious problems than us.

????: that can be solved.

Y/n: who are you?
(Kazuya)

(Aleph or Hawk)

(Naoki/Demi-Fiend)

(Flynn)

(Nanashi)

(Raidou Kuzunoha XIV)

(Cielo, Gale, Sera, Serph, Heat and Argilla)

(Naoya/Persona 1 Protagonist)

(Tatsuya Suou/Persona 2 Innocent Sin/Enteral Punishment Protagonist)

(Maya Amano)

Akeno: who are you people?

Kazuya: Kazuya.

Aleph: Aleph or Hawk whatever you want.

Naoki: Naoki or call me Demi-Fiend.

Y/n: Tatsuya, Naoya!? Wait, Maya!? What are you doing here!?

Maya: to help you deal with your own shadow.

Y/n:*looks down*

Tatsuya: yeah my shadow also taunted me but this shadow of yours is very much deadly to you and we'll help you.

Flynn: yes we'll be training all of you to be stronger even stronger than all of us.

Junpei: for real!?

Ryuji: that's my line!!

Heat: we're gonna get you all stronger and take that god's ass down!!

Dante: hey don't forget about us!!

Irina: Dante!?

Dante: yep we'll help you also.

Y/n: looks like we have our hands full.

(Meanwhile)

Shadow Y/n: my lord we have a problem....

YHVH: yes?

Shadow Y/n: Y/n is able to awaken is Juggernaut transformation.

YHVH: what!? Dam him!! If he achieve all of the powers then he'll able to kill me, erase me from existence!!

Shadow Y/n: what should we do my lord?

YHVH: I'll send one if my avatars to destroy them. I need to charge my power to create a portal to a different world if I'm erased. Soon Y/n will face not just the shadows of demons but will face true demons before my death.

Then the screen went to black

Messiha: One of Y/n's Final Personas. The term messiah (in Hebrew) or Christ (in Greek) is prominent within the world's many religions, especially in the Abrahamic religions Judaism and Christianity. A messiah is regarded as a savior of mankind who would bring them salvation near the end of days, although opinions between who the term messiah refers to differs between religions.

The most common opinion in the West is the Christian one, which holds that the messiah is Jesus Christ. Other messiah figures have appeared in both history and myth and people have placed their hopes in them for salvation, Buddha, Krishna and Maitreya being examples. He Appears before Judgment Day to save the virtuous. He is a universal figure, appearing in myth around the world. Many stories involve his death and rebirth.
