How to Survive with a Life Note

A deathnote fanfic:
Life note has the ability to revive people UNDER certain circumstances. Kokomi, a happy and normal teenager, find herself in death note during her vacation at Japan. Strange enough, her phone for some reason can work just fine cross dimensionally and connect to a death note fan website from another 3D world.
In that 3-dimension, death note anime just started the first season and Kokomi can see herself in those anime.

Kokomi: I'm in my favorite anime! (Deathnote) Oh why can I see myself in the anime?

car crash and saw kira killing people.

Kokomi: HELP!!! I'm still a child! Oh wait there's a life note.

Light: WHO and WHY is this person going against me?

L: she appeared out of nowhere too... Will you join the task force? But it would be nice if you reveal your true identity.

Kokomi (owner of life note, rival of kira): No thanks!

Comments Section: She MUST be the final boss!

Kokomi: No I just know the plot.

Pov: people keep thinking i'm the bad guy
