The bookworm Princess of Crescentia.
She’s also extremely talented when it comes to tinkering and mechanics.
Passionate about her home, Marylyn spends most of her days reading, tinkering, and sometimes watching over the Knights in training. She doesn’t often venture out into the Kingdom itself as you can tell. This leaves her to be… a bit socially inept to say the least. She’s still eager to get out there when possible though!
Watching over the Knights in training is how she met Edric! Impressed by his resolve to be the best Knight possible and after… certain events, Edric became her royal advisor! It’s a bit unheard of for a Captain of the Knights of Crescentia to be both that and a Royal Advisor, but they pulled some strings.
The two are so close that Edric still uses the same prosthetic arm she made for him. It seems he doesn’t need it, but he uses it anyway… curious. The two must really like each other!

Powers: It’s only natural the Princess of Crescentia has achieved Act 3! She can reverse an item to its components and reconstruct something almost instantly. This combined with her knack for mechanics allows her to be able to make some truly fearsome robots! (Think of her Act 3 as something similar to Josuke’s ability from JoJo: Diamond is Unbreakable)
