A very well-appreciated surprise! >:D I was really wondering when we'll get another serious arc, and what more one with both Takasugi and Kamui. I thought it was pretty surprising that they included the big factions (Yorozuya, Shinsengumi, AssassinGroup, SHOGUN!!!) especially since they normally focus on one faction at a time. But this is a nice set up. Really marks the 500+chapters well indeed. Hope it gets more intense!!
