3rd person POV:

Above the Demon lords castle flew two beings, or more specifically the same beings from different periods of time.

Orbiting around these two were energy blades that would zip around the air trying to attack their opponent.

The two flew around in the air like streaks of light.

When they clashed, it caused shockwaves that knocked down every one near them.

(Battle theme)

(Y/n) charged towards his past self. He sent several blade constructs ahead to distract the Demon lord so he could get closer.

The Demon lord swung around his sword that had his own blade constructs following it. With several slashes, he got rid of his future counterparts' blades.

When (Y/n) got close enough, he went for a horizontal slash, which his past self avoided by falling to his back.

The Demon lord then slashed at (Y/n)'s chest hitting him multiple times due to the construct blades following his sword.

He chuckled at the attack he landed but when he felt several blades pierce his back his smirk turned into a scowl.

The (Y/n) of the past thrusted his blade at his future self, only for him to obliterate his sword with the power of Exceed.

Before (Y/n) could attack his past self again, the Demon lord blasted a stream of demonic magic into his face, sending him flying back.

The Demon lord flew towards the Emperor of angels.

Arriving above him, he was going to go for a demonically infused punch.

(Y/n) then quickly flung his blade into the air and went to meet his past self's attack with his own holy infused punch.

When the two fists got near each other they began repelling the other like a magnet, however, the two continue to push against the force.

Dark purple energy began coagulating in the middle of their fists.

Demon lord: I don't know who you are, but I will take much joy in destroying you!

(Y/n): I know you would because I feel the same about you, but sadly that's a form of suicide on both sides of that fucked up coin!

As their fist got closer and closer together, the dark energy between their fist began condensing while growing stronger.

Before their fist could finally meet and set off that dark energy, (Y/n) called Exceed and caused it to land in the back of his past self.

Reeling back in pain as Exceed slowly began erasing the magic in him, (Y/n) took this opportunity to spin around, smack his past self with his tail, then grab his sword out of the Demon lords back.

Kicking him into the castle, (Y/n) then used his Retirement plan to erase into ash the dark energy that had stuck to his fist.

Ciri and Sophia were finally able to stand up.

As they did, a new portal through time and space finally opened.

Ciri: (Y/n)!

She shouted as she got in front of the portal to stop Sophia from entering.

As (Y/n) quickly began flying towards the two, Sophia tackled Ciri into the portal, causing it to slowly close.

(Y/n): I'm going to deep fry that bitch...

Flying faster towards the portal, when he finally was about to enter it, someone tackled him into it.

Demon lord: We're not done playing!

With two (Y/n)'s in the portal, the portal became extremely unstable.

The two began beating up each other, while Ciri and Sophia did the same.

The two girls were able to exit the portal, but at the speed, the two (Y/n)'s were traveling it didn't seem like they would make it through.

(Y/n):(mind) You know what...? The timeline can suck my cock!

Stabbing his Demon lord self, causing him to flinch, (Y/n) grabbed his past self, headbutted him until one of his horns broke. Taking the horn, he stabbed his past self again with it, then kicked him away.

The Demon lord then went through the wall of the wormhole, disappearing into who knows where.

(Y/n) then flew full speed down the wormhole and barely managed to get through.

Rolling across the ground, he reverted back into his normal form.

(Y/n): Where and when am I now...?

Hearing the battle Ciri and Sophia were having in the background, (Y/n) slowly got up.

The area around him was bright as day. The floor had a layer of clouds that hid his feet from view.

(Y/n): Heaven... Lamer then I imagined.

Familiar voice:(grumbling) Why do I have to do this crud... I'm better than this...

(Y/n):?

Ciri and Sophis clashed blades.

Ciri then placed a foot on Sophia's chest and vaulted herself back. Flipping mid-air, she landed on her feet.

Using Excel, she fired electricity at Sophia, who fired a wave of holy fire. Their attacks canceled each others out.

Ciri: What even is your plan?

Sophia: Simple, tell my mother my father's plan, and convince my siblings to join my mother's side.

Ciri: Please tell me that was your idea because I don't want to believe the goddess of the universe is an idiot.

Sophia: Watch who you're talking to...

Ciri: Damn, I'm right...

Using her wings, Sophia slashes down at Ciri, who blocks the attack with Excel which she coated in demonic magic, causing Sophia to feel pain as her wings landed on Excel.

Rolling to the side, Ciri blast Sophia with a bunch of small ice shards. The shards land in Sophia's side, she grits her teeth to hold back a yell of pain.

Sophia then smacks Ciri back with her wing. Before she hit the ground, Ciri used Excel to blink behind Sophia and slash her back.

Using Excel to enhance herself, she prepared to knock Sophia down, only for her to spin around and knock Excel out of her hand.

The two began fighting in hand to hand combat. Ciri's engagement spells allowed her to fight on an even playing field.

The two knocked each other back. This allowed Ciri to call Excel to her. Excel came flying back into Ciri's hand.

The two then continued their fight.

Meanwhile, (Y/n), after hearing a familiar voice grumble behind him began turning around to see who it was.

As he got a look at the person, he first became confused at who it was he was looking at, but the longer he looked the more it became obvious.

There was a pain in his chest as he realized who it was. Trying to speak, (Y/n) ends up only choking on his words.

Archangel: Huh?

Archangel: What the heck is wrong with you? Demon got your tongue?

(Y/n): M-... M-... M-...

Archangel: M? Tch, Of course, an Idiot finds himself in heaven.

She begins writing in a notebook.

Lucifer:(sigh) What a bother...
