Though I'm sad to see your characters go, I think you made the right decision, ultimately. I hope that you feel more comfortable with this character count and your activity can continue to improve.
I also think that, regarding the huge chunk of crit you got last month, you've improved immensely on your activity. There's still room for improvement (which I know you're aware of, hence the dropping of characters), but overall I think you're doing a good job tagging around with everyone. It really seems that you're consistent with everyone and getting tags back. The only two that seem to still be giving you trouble are Fujimoto and Hikaru, since both of them seem slow to give tags back. But, hopefully this weeding of characters will help improve their activity, as well. Overall, great job!
I think you continue to be fantastic with Ioryogi. His threads are always so much fun and hilarious, but then I love seeing his more serious side when he gets prodded in that direction. He's well-rounded and, more importantly, fun. I love seeing him around and playing with him.
I know you've also been worrying about Sakura and whether she's doing anything, but I think she's been around consistently lately and actually been engaged with the game. She doesn't just seem to be there to sparkle and be adorable, but she actually has threads that progress and lead to new or stronger CR. I like the way she handled Syao's disappearance, and I love her in the Halloween log. She's adorable, as always.
As always, I'm astounded by your ability to not only play so many characters, but to also play them well. I honestly have nothing to say about characterization. They are all so ic and wonderful, and it's amazing that you can give all of them a distinct voice throughout.
