@RobertG22 - Quite the contrary, Renji isn't my favorite of the Gotei Lieutenants, Hisagi is. I suggest as such, because as lieutenant so far he has shown the most development - Bankai etc. Renji is slightly leader material, during the Vandenreich invasion he guided his little minions away quite well. Lots of people hold respect for him too and admire him. He hasn't shown a huge amount of leadership due to the fact that not many 6th division interactions between unseated and seated officers has been shown compared to other divisions. Most times he tags along with Byakuya or Ichigo. He wouldn't be in charge with Byakuya around, and Ichigo is simply a friend. Hakuda and Kido? Shunsui hasn't shown one Kido technique yet. And he is more or less the strongest captain besides Kenpachi (you cant consider him a captain, more like a rabid dog on a leash) And his Hakuda is pretty amateur, Shunsui's is one of my favorite characters, but currently Renji has shown more prowess in Kido than him.

Yeah I doubt Senjumaru created Kido itself (poor choice of words, I was too lazy to list the Hado and Bakudo techniques)
