Y/n: how I'm going to beat him like this!?

Kirito: no not him your...

Ain: going to...

Add: face us...

D.Y/n: as one being!!

They all merged and reveal their new body... Mangetsu.
(Meaning Full Moon in Japanese)

Y/n: no way!!

Mangetsu: i will kill you Y/n if you don't raise you sword!!

Y/n takes out Tensa Zangetsu while Mangetsu takes out Euclidator and Dark Repulser and they both attack each other.

Y/n: HAAAAAAAA!!!

But Mangetsu counters all attacks and hits Y/n with the sword back up he uses Getsuga Tenshou.

Y/n: holy shi-GHAAAAAA!!

His felt his stomach was kicked and send hurling towards the skyscraper roofs but luckily he dodges Mangetsu's attack. He uses Stinger and Overdrive with another Stinger following with Million Stabs.
(Meanwhile at the battlefield)

Shallot: Wild Cannon!!!

Gogeta and Vegtio: FFFUUSSIOONN!! HAAAA!!

Gogetio: ALRIGHT!! GOD PUNISHER!!

Barrages of Ki Balls hit Ironwood causing mega damage his healing was not working correctly and Yui uses Gogeta's attack.

Yui: SOUL PUNISHER!!!

The rainbow ball of Ki contacted James causing it to exploded on impact and the smoke reveals him bleeding.

Ironwood:*huff x3*

Naruto: RASENGAN!!!

Vegeta: Galick Gun!!

Goku: Kamehameha!!!!

(Meanwhile back at Y/n's Inner World)

Y/n:*huff 4x*

Mangetsu: give up boy you will never win.

Y/n: no!!

Mangetsu: why?

Y/n: I'm not going to give up on my wives, my family and my friends!! Teach me the Hybrid Trigger!!

Mangetsu: no I will never teach you until you give up!!

Y/n: then I'll have to beat the hell out of you!!

Y/n glares at Mangetsu while he just stares at Y/n's eyes then they backed off.

Mangetsu: HERE I GO Y/N!!! HAAAAAA!!

Y/n: HAAAAAAAAAA!!

They both collided their swords but then Tensa Zangetsu's blade is now broken. They turned around and looked each other at the eyes Mangetsu attacks Y/n as Y/n tries to reflect the attack but was knocked back.

Y/n:*mind* I don't understand, he has me at a complete disadvantage but why do I feel sadness from him and the blade?!

Y/n blocks Mangetsu sword attacks but without the blade he gets knocked back. Mangetsu charges at Y/n but Y/n smiles and let's go of the sword as Mangetsu widens his eyes but it was too late.

(Back at Atlas Again)

Sachi:*huff* even with our combined attacks he's able withstand all of our attacks!!

Yang: yeah!! He's one tough bad guy!!

Lucifer: BLAZING BARRAGE!!!

He throws barrages of black fire balls at Ironwood but it did barely any damage and he kicks Lucifer's face causing him to spit blood out of his mouth.

Ironwood: HAHAHAHAHAHA!! YOU FOOLS HAVE FAILED AND I'LL BE RULING THIS WORLD NO THE UNIVERSE WITH AN IORN FIST!!

Suguha:*mind* please Y/n!!! Save us!!

(Back to Y/n's inner world)

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

Y/n:......

Mangetsu: you finally figure it out. The only way to acquire the Hybrid Trigger is to give up everything and accept my blade along with accepting both your inner angel and inner demon*tears form*.

Y/n: why are you crying then?

Mangetsu: because the path you have now chosen. Do you recall what I said when we were not fused and we fought?

(Recall)

Add: you need to understand something what you want to protect Y/n is not the same thing that we all want to protect.

(Recall Ended)

Mangetsu: what I wanted to protect is...is you Y/n!!

Y/n:*eyes widen*

Mangetsu: I want to protect you, I see you in pain when you fought Cinder Fall and awaken the Blue Flame Devil and the Devil Trigger of it, I was in pain. I cried that you were in pain I was worried that you'll die!! I don't want to lose you!!

Then Mangetsu let's go of the hilt and he was gone but his voice was still there before it was gone.

Mangetsu: the answer is within the blade Y/n, if you use it you have to make a sacrifice because your immortality is in a limit.

(Real world)

Ironwood: YES I'LL RULE THE UNIVERSE WITH AN IRON FIST HAHAHAHAHA-WHAT!?

The ground began to shake buildings were falling down. Then the ocean erupts reveal a black/white ball and it blasted to Atlas at high speeds that it out runs many blackholes.

Lucifer: what the?

The ball landed and vanished to reveal Y/n in his new form and his new swords.

Y/n:*eyes open to reveal his golden eyes*

Yui: papa?

Y/n: this is your end James Ironwood and your punishment will be erase from life itself so you will never exist.

To be continued!?
