Yet, a warm voice whispers a second chance, a new world. Transmigrated into the world of Oshi no Ko, Akira now holds the keys to potential stardom.

Some more information before you hop into the fic:

This book is very much inspired by the movie Yesterday and a fanfic I read: The Betrayed Hero and the Idol, but I want to keep the supernatural stuff to a minimum. Also, Akira will be using songs from this world as they don't exist in the world of Oshi No Ko. Akira is a performer, not a songwriter and the only one who would know the songs are not his is him.

For full transparency I write the novel myself and use AI to proofread and be an editor for my work.

I am more familiar with pop and rnb music so that is what I will be using most likely

Since the timeline in OnK is confusing, I am going to go ahead and make my own:

Ai Birthday: Jan 25, 2002

Akira Birthday: June 11, 2002

Aqua and Ruby birthday: April 28, 2018

Date when Akira Transmigrates: October 3, 2019 <<less

A MULTİVERSE FANFİC ... more>>

After Peter's family died at the hands of a criminal organization, Peter began living an isolated and lonely life.

As the years pass in this way, Peter one day meets the system, which tells him that he can become stronger by doing tasks in the multiverse, and at the end of the years, he agrees to merge with the system, thinking that he has the opportunity to avenge his family.

Uzume, who was sent to Peter with the system, tries to make Peter a person who knows how to be happy again while traveling the multiverse.

-------

Although the main character is smarter than a normal person, he did not receive a proper education or grew up in a family environment, so the main character's emotional intelligence is very low and Uzume tries to help the main character in this regard.

The Venerable One, Reincarnator Extraordinaire, has lived through all. Nine lives showed him many shades of life; he was a Hero once and Demon Lord in another; again a Heavenly Beast and a Time Manipulating Vampire in another. Finally, a Cultivator in his latest. He was a little insane in his head by now, but hey maybe that's the perk of living too many lives.... more>>

He finds himself in incredible joy as roots die hard, and he is reincarnated in a Modern World as a mere human in his 10th (?) life.

But…
