A carefree high school dropout, she never had the drive to do anything with her life. Now that she has nothing to do, she has decided to spend hours of her life every day devoted to studying the concept of time travel.
Dropout Marker is a marker with a light blue cap and emblem. She wears a black bowler hat, a dull purplish red shirt and a navy blue jacket. She has bags over her eyes, indicating insomnia or tiredness, as well as being the only marker to have eyelashes.

what a nerd 

Yellow Marker is mostly a joyful happy person by surface appearance. He runs a fishing shop in the local area and enjoys talking to visitors. Just don't go in the attic... or work for him... or... talk to him...

- Yellow Marker is extremely similar to Purple Marker, just being coloured yellow instead of purple on the cap and emblem.
