For a 'Kamen Rider crossover feudal Japan' fanfic, a Kamen Rider would be a must - have main character. In addition, a ronin, a masterless samurai, could be another main character. This ronin could have his own code of honor and be very skilled in combat. He and the Kamen Rider might meet in a dangerous situation, like being chased by bandits. And there could also be a young princess who is caught in the middle of a political intrigue in the feudal court. The Rider and the ronin might end up protecting her and in the process, get involved in the larger events of feudal Japan.
