A while back I did a thought experiment of trying to make a Ridebook set out of my favorite mythical beast, real animal and story. I think she turned out pretty cool:

Kamen Rider Stiletto
Forms work like Buster, Kenzan and Slash
Theme: Mirror, Spider
Sword: Senkoken Sakushi (Flash-Sword Optical Illusion)
Wonder Ride Books: Lady Demon (mythical beast, based on a succubus), Web of Spider (animal), Jekyll And Hyde (story)
Forms:
Web of Spider: main form, built for speed over defense
Spider Demon: super/berserker form, greatly increases attack power
Spider JekyllHyde: splits into two copies, one calm and one wild
Backstory: a woman who was connected to the Wonder World, Legiel tried to use her to create the Lady Demon Megid, but instead of turning her into a monster the Megid chose to act like a dark side within her. While searching for answers about what was going on, she found the Sword of Logos and ended up joining the order when the Sword of Mirrors called out to her. For a while she struggled against her Megid side, but after facing her inner demon (literally, she used Jekyll And Hyde to split in two, give the Megid control of the Hyde side and have a duel with herself), she gained control of Lady Demon's power.
