New York

With Trihexa in New York (Y/n) faces the beast as he slices one of his arms with Dismantle which generated instantly which Trihexa counters with a punch in the body as (Y/n) was sent flying and felt some of his ribs break.

(Y/n): Damn it...

Trihexa swung its tail and (Y/n) dodges it by jumping on its tail until he uses is ice powers and froze it as it breaks from (Y/n)'s fist

(Y/n): This is harder than i thought...

Kurama: (Y/n), Try using tail beast bomb!

(Y/n): Got it...

(Y/n) went and did a finger gun motion as a Tail beast bomb starts charging.

(Y/n): Bijuu Dama...! (Tail beast bomb)

(Y/n) launches it until Trihexa fires an energy beam which (Y/n) was silent.

(Y/n):.......*Looks at the screen* Why do i feel like the Author gave Trihexa more abilites and powers...

Kurama: Oi! (Y/n)! Who the hell are you talking to and keep fighting!

Suddenly a veil surrounds the entire area as (Y/n) got pissed.

(Y/n): Well shit, This just got a lot harder for me...

(Y/n) slices a curse from behind as he brings out a giant sword and says its name.

(Y/n): Bleach, Zangetsu...

(Y/n)'s spiritual pressure rises up as he points his sword on Trihexa.

(Y/n):.......Guess i need to be a bit serious...

(Y/n) rushes in with a nameless getsuga which slashed Trihexa, He aimed to slice its entire body.

(Y/n): Getsugatensho...!

(Y/n) unleashes the getsugatensho as it his Trihexa and sliced its arm and slashed its body which regenerated instantly as (Y/n) was slammed into five buildings building into the floor as he pukes blood as he wipes some blood on his head.

(Y/n): Damn it, too strong...

A bunch of curses appear out of nowhere as it was gonna attack (Y/n) but all their heads where instantly cut off as he saw a chain with a mace as he sees.

(Y/n): Rem...

Rem: (Y/n)!

Rem rushes and hugs (Y/n) as he sees his state.

Rem: Are you alright!

(Y/n): Rem...Why are you here...?

Rem: Mr.Adrian said i need to find you, right now everyone is evacuating civilains and others are fighting Trihexa.

(Y/n): I see...

(Y/n) stands up as he walks until slicing four curses with Zangetsu.

Rem: (Y/n) Please dont overwork yourself, you took too much damage!

(Y/n): I have too Rem...

Rem slams her chained mace on a curse destroying it instantly as she looks at (Y/n) worried.

Rem: Please think about this...

(Y/n) looks at Rem and looks away.

(Y/n): Im sorry...

(Y/n)'s body flickers as Rem screams his name as he appears infront of Trihexa and sent him back by using.

(Y/n): jutsushiki hanten...Aka..! (Cursed Technique Reversal: Red)

(Y/n) knocks back Trihexa a bit as it throws him into another building to where his friends are in and who were killing curses.

Itadori: (Y/n)!!

(Y/n) gets back up as he coughs out blood as he starts healing by using Wolverine's healing factor but he notices he heals slower.

(Y/n): *panting* this son of a bitch can Nullify my powers? Not to mention it keeps healing and ragdolling me in buildings...how do i stop it...*Sigh* Where's Deadpool when you need his healing factor...

(Y/n) slices eight curses with a nameless getsuga as he looks at one of his friends.

(Y/n): Megumi...Where are the others...

Megumi: The others are currently evacuating civilians, and were tasked with exorcising curses.

(Y/n): I see...Keep killing them, Ill hold off Trihexa...

Megumi: (Y/n) wait, Let Asia heal you first.

(Y/n): No time...

Sword of Vengeance

(Y/n): It nullifies its healing factor...Not bad Adrian, I guess stealing from your Weapons vault was worth it...

(Y/n) slashes its Arm as Trihexa roars in pain and as he was about to slice it again two blurs went past him and Arthur aswell as Musashi slices it with him.

(Y/n): Arthur, Musashi...

Musashi: Yo Master!

Arthur: Are you okay?

(Y/n): Ill be fine, I still got some fight in me even though Trihexa can nullify my powers...Where's Scathach, Ereshkigal and Ishtar?

Musashi: They're currently fighting shadow servants behind us right now.

(Y/n): Shadow servants aswell...this is tricky...

Trihexa roars as Thor and Tony land beside the three.

Iron man: Whats the plan kid that sword managed to cut it without healing.

Thor: Agreed, The beast must be killed if we cant find a way to harm it.

(Y/n): already came up with 10, And we gotta make it quick i cant use the sword of vengeance too much because this thing steals a crap ton of energy and could possibly kill me...

(Y/n) and Tony rushes in and slashes Trihexa's chest making it roar in pain again as he traps its entire body with ice as Tony blasts it destroying it i nthe process as thor slams his hammer on the ice.
