A samurai reverse harem anime? Yes, and a good one, so far. A real story, involving the Shinsengumi. Good animation and backgrounds. Some action. Characters with presence. A heroine played by Kuwashima Houko. Heroes played by Shinichirou Miki, Morikubo Showtarou, Toriumi Kousuke, Yoshino Hiroyuki, Ohkawa Tohru, and others.
About the only thing I find wrong with it is the difficulty of keeping all the names and faces straight.
So I've made a characters/seiyuus page with pics of all the main characters (the thirteen whose pics are on the official site) and their seiyuus, with a bit of info about each seiyuu. Click here or on the image to go to the full page.
