A/N: Yo everyone, sorry I haven't been posted to these past months and the school have been killing me for some reason including this Math subject. I don't hate math since I was pretty good at it except for solving. So anyways, let's go to our story. This is the continue of his backstory after he got sucked on the portal.

No One's POV:

Izuku opens his eyes and sees himself in Unknown Place and looks around. It is full of purple piercing rocks and in the dark place just like domain dimension{not expansion}.

Izuku: Where the hell am I right now? am I supposed to be in nagazora?

What he saw.

Izuku:

Izuku: Holy crap! I need to find the exit of this place!

Suddenly, he felt a tremendous pain on his head and screams in agony while holding his head with both of his hands.

Izuku: AGGGGHHHH!!*on his knees with both of his hands on his head*

While he was screaming, an unknown voice was coming from his mind and said this.

???: Remember... everything...

The voice from his mind is somewhat cold and serious but calm.

Izuku(Mind): Who are you?

???: It doesn't matter who I am, I'm only here to make you remember everything from your past on 350,000 years ago.

Izuku(Mind): What are you talking about?

???: Like I said, I'm here to make you remember everything from your past.

Izuku(Mind): My... Past..?

???: Yes and go.. Remember everything what happened to your past when you were the 'Leader Of The Ten Commandments'.

Izuku(Mind): Me? A lead-

Suddenly, a memory from his past that he had a yellow hair with a big semester mark on his forehead while had ten people behind him.

A/N: Changing scenes.

Izuku{???}:

???: That power you had back then, you almost destroyed half of the humanity in your pure rampage. During your reign... Your strength, your power, your ruthless, your callous disregard for life... It was terrifying and majestic sight to behold. In the face of that back then. The honkais and herrschers couldn't do anything..

???: ..but tremble in fear on your own unstable demonic power..

???: Everyone in the demon clan accepted and acknowledged you as the true worthy successor to the demon king. Until a new Herrscher appeared and it was stronger than all of the Herrschers besides one Herrscher. That new Herrscher was none other than 'Herrscher Of The End' herself.

A/N: Scene Changes.

Seeing the Herrscher Of The End killing a lot of demons including humans with her own power, many demons were on the ground with a pool of blood while the others was pierced by a many spears. Until.

HoE: *senses a great dark power and looks back* Who are you. Your one of these ugly demons right?

Izuku(???): ...*looking at the dead bodies laying everywhere with his green eyes{normal} and looks at her* A piece of advice..

Izuku(???): ..You see hell if your toughness is limited..*showns many black sparks around him and engulfed his big sword with dark energy and a big senester mark appears at his forehead*

HoE: *eyes widen* That senester mark of yours, you're the-!?

Izuku(???): You're just a full of talking.*rushes towards her and jumps then sends a slash at her*

However, the Herrscher Of The End didn't react and gets cut into half by him.

Izuku(???):

Imagine the goddess is HoE.

???: You even killed Herrscher Of The End like it's nothing to you back then, that is why everyone including the humans named you 'The Most Wicked Demon'. But still the Honkai Energy is still intact to this accursed world, it will mean that she's still alive until now.

Another memory appeared at his mind.

A/N: If you guys tired of the story, I'll make it skip a long time. It also happend in canon of SDS but the Honkais were not there cause they got sealed by the demon king for 300,000 years. So the goddess clan appears instead back then and fought the demon clan in canon in holy war, Izuku's past life was none other than Meliodas.(this is his past.) So the other clans like Giants, Fairies and Humans in the past don't know anything about honkais except the demon and goddess clan.

His mind went black as he snap back to reality.

Izuku: I... remember everything..

???: *in izuku's mind* Yes you did.. Older Brother..

Izuku: *chibi form* Thanks for remembering me everything, Zeldris!

Zeldris: *in izuku's mind* I don't need your thanks Izuku or should I say Meliodas.

Zeldris: *in Izuku's mind* This will be the last time you will see me. Meliodas, I don't have much time left.

Izuku: ...*smiles a bit* I see..

Izuku: Then you can go now, Zeldris. I bet gelda is waiting for you to come back.

Zeldris: *in izuku's mind* *starts glowing* Yeah..

Izuku: And tell everyone say hi for me.

Zeldris: *in izuku's mind* I will..*smiles as he fades away*

Izuku: ...(I'm all alone again huh.)

Suddenly, the purgatory started to collapse as izuku was still standing there. However, a dark energy was on izuku's face as his eyes were became dull black looking at the above.

Izuku: AHHHHHH!!!!!

He screamed in agony and a huge dark energy explodes destroying the entire purgatory.

A/N: Peace.👌
