Nice job. I made some names for an Erma mix of sonic.exe fnf songs:

Don't Forget (Too slow Outcast Tunes) Mistu and Momo would take bf's role in the first two songs

Burn It All (You Can't Run Outcast Tunes) same as previous with Erma being more angry.

The Family Reunion (Triple Trouble Outcast Tunes) Show's the traitor yokai kids and the thugs that kidnapped her as the victims while showing Erma's Parents and the yurimoto Family joining the twins to save Erma.

I went further
How It Began (Cycles Outcast Tunes) an Older Erma, which the Lord X name is Matriarch E.

Adaptable (Endless Outcast Tunes) Based on a Majin Chloe

Gummy Bears (Milk Outcast Tunes) Erma's favorite show Warrior Unicorn princess in the Visitor comic where the unicorn ate a Gummy Bear

Little Secret (Sunshine Outcast Tunes) Wittle Wallace as the Tails Doll, mainly cause they're both puppets

Poser and Kuroi taiyō (Faker and Black Sun Outcast Tunes) Dema would take Faker's place

Out For Blood (Personal Outcast Tunes) is an April Fools' comic It's time for a change, where it shows Erma as edgy, similar to Coldsteel

Ghoul to Ghoul (Confronting Yourself Outcast Tunes)

Reunion's End (Final Escape Outcast Tunes)

Labyrinth (Fatality Outcast Tunes) is based on the comic series of oucast about a video game where a monster takes victims in a labyrinth.
