Norrie seems like the kind of person to write one, I think simply "Victor" as the title as an homage to her grandfather, her Stoutland (who is still alive) and as an alt name that ppl called her instead...I think all her chapter names would be in spanish tho

"So, You Exist... Now What?" by Odd Lambert

Some chapters:

"Technicalities on What Makes A Faller"

"When Your Best Friend is a Talking Pokemon"

"Coming to Terms With Being Forcefully Vivisected as a Child and having a Second Brain Implanted in you in an Experiment to Bring About the Near Apocalypse"

"Favorite Travel Spots"

Gordon might. "Better Haunted Than Stagnant"
"Solving writers block through psychological attacks"

Balei is my oldest oc so she would have a lot to write about, the book would be called “Island Flower” because she from Alola, Oricorio transform with nectar from flowers, and she’s a dancer

I think every chapter about an important event in her life would be named after a flower from Alola (aka just real life Hawaiian flowers) One could be Hibiscus, a chapter about her meeting her husband for the first time

Minerva would have some edgy shit like “Clawing Through the Shadows” or something.

Wings of Redemption by Sarin Greyflock

Mary would go with something like "The Show goes on". With chapters like "My world burning", "New face", and "The day I met Darling".
