oh fuck yeah . I used to have a crush on Saitou (Aoshi was my main husbando though) until I saw how he looked like in real life.
Nuri is right, watch the series first. Stop after the Kyoto arc if you want to follow the manga. What happened is that after the Kyoto arc the author wasnt writing as fast as the guys doing the anime so they started creating "fillers episodes" that sucked SO MUCH that the ratings dropped, taking the series out of tv.
Omg its like going back in time! this used to be my number one series, i even made a webpage about them lol (nerd, i know). It was even on tv, it was THAT good.
