A little older but been playing around with this OC and her story! The pending story name is "Miss Terri at Glenwood Grove", but that is subject to change :]

She's a Private Investigator on her first case with her best friend Joseph, and while her system does try their best to work together, amnesia barriers mean that things slip through the cracks sometimes. I figured it'd be a fun mystery story to have the audience get clues and piece things together possibly faster than the characters and get to see how the characters piece things together :3c

The Peppermint System consists of:
Minty herself, the host
Penny, the syskid
Logan, the protector
An unnamed caretaker
And Rodwick, the avenger/ex persecutor

Minty calls Rodwick "Hotrod" and he calls her "Menthol". They are a match made in heaven and if they actually sat down and talked instead of constantly teasing each other would probably make a very cute insys couple <3

I did also decide that PMS as a whole has some form of aphantasia and Minty and Logan feel it the most. So they are completely unable to see anything in their mind, whereas Penny, Rodwick and the caretaker can all see somewhat. :3 So if I were to ever make this a published story, Minty and Logan's POVs would be written story and everyone else's POVs would be different comic artstyles !

Idk how much I'll actually end up developing her story but for now it's a fun lowstakes story to play with :]
