...yesterday, I just realized that there was a PERFECT canon Kamen Rider to use in an RP. The "Vanguards of Hope" is a remarkable good fit.
Hibiki. An Oni Rider would fit in completely. The more demonic, visceral nature of the monsters would fit with his abilities, arsenal, aesthetics. The use of "Pure Sound" can be treated as a "Purification". It is even established in canon that with training, an Oni can use ALL types of weapons(beat, wind and string aka drumstick, trumpet and guitar). Oh man, you have SO many things to play with using an Oni Rider character.
Now the question is whether it's feasible go for it. Though I have one character for now, the game already has a big cast as it is. Just asking your opinion on it. And, if you support the idea, do you have anything you want for this character? Any thoughts or themes you want to see worked in? I have a basic idea of the character but I want some outside input to build it up.
