(The following is just on those I can't seem nor feel like doing a what if on personally.)

As Ovalsan enter what seems to be a soundstage and takes a CR directors chair that's in front of a green screen-

So I can talk to you the reader, now before I begin the green screen behind me is it display images of those that I can't personally not able to make a what-if story on.

Starting with the Death Note series I have no idea on words begin without making it into a joke even as a completely original story and while I'm at it's if you want my opinion on the game Death Note the killer Within it looks like a team-based Among Us even if it is intentional the other ways that Death Note game can work if it is a overly complex visual novel where one wrong choice will have you be Kira's next victim was something similar to the Another code series.

May take the Light Shinigami into consideration but will still sound like a repeat of the whole series with what I have in mind.

Can Percy do rewrites of those like Steven Universe don't want to change history nor do those that are still going on or ended on a cliffhanger because it's still be a guest like one else's can't make original story out of what I have in mind.

Needless to say I can only do personal continuing but you may already know that anyway.
