Rurouni Kenshin is likely that one series that ends up being so hard to actually cross over because it not only has a self-contained story that already has a solid plot on its own merits, but also a protagonist that has completed his journey and would likely cause more problems given the concept of killing comes up for better and for worse.



Then again, that could end up being a good source of character development in its own right - Kenshin becomes the mentor to a new generation and helps him learn the right lessons before it's too late.



And if Shinkenger is going to take the spotlight, so to speak, then it actually kind of all works out in the end!
