Do you know what it feels like to get shot in the face? A bullet straight to the face?

Yeah, it's a type of quick death where you wouldn't have to feel much pain, but I'm sure most people wouldn't love to die that way...

..But that's exactly how Aiden died. He was shot in the face by the leader of the gang he was in, and it was instant death for him. He joined a gang due to the troubles of life, the unfairness of life, and that's what caused his death.

But that wasn't the end for Aiden. After meeting with the demi-gods and choosing a path, he passed through the cycle of reincarnation and was reborn as a baby into a world where superpowers exist...

..A world where your power element determines how far you'll go, a world where not everyone gets to possess an ability, a world where magical beasts exist.

Aiden would have to survive in this world, he'll have to become stronger to do that, he'll have to awaken an ability. Luckily for him, he was granted something no one else possesses...

[ Ding! Ding!]

[ You've been granted the Undefeated System]

With this system, Aiden can become stronger by conquering females, by banging them. This was gonna be of big help to him, the Undefeated System was gonna take him far.

His journey begins...

When Caesar learned that he had traveled to the world of pirates!

In order to become stronger, I started hell-style training, looking forward to going to sea one day,

Stir up the situation and rule the world!

One day, a pirate group came.

Looking at the familiar figures behind the captain,

Caesar instantly knew his name – Lockes!

After the Island of the Gods incident…

Garp: When did a Caesar appear in the Rocks Pirates? Almost fell into his hands!

Roger: What kind of strange ability is this? Domineering! ?

White Beard: The scars on my body are thanks to Caesar!

Golden Lion: How is it possible! What ability is he hiding! ?

Kaido: Bastard, it turns out that this guy has been paddling all the time!
