User blog comment:Dangai Train/Ryuken's true motives/@comment-6657474-20140216002432

I think it's likely that Ryuken's feelings towards the Shimigami is more like resentment with possibly a tiny bit of grudging respect. After all, unlike Uryu, to the best of my knowledge, he never expressed outright hatred, and he was genuinely surprised when Isshin sacrificed literally everything to save Masaki. The only hint of hostility I can think that he expressed in the present timeline was when he forbade Uryu from getting involved with Shimigami in extange for restoring his Quincy powers. In terms of Uryu's increase in power during the previous arc, there's no real evidence to suggest that Ryuken had anything to do with it, so I think it was most likely self-training on Uryu's part, especially since most of the equipment Uryu used during the attempt to rescue Orihime was STOLEN from his father's hidden storeroom. I have to imagine that the reason the Wandenreich didn't recruit him was because, although he would most likely want revenge for Katagiri and Masaki, he was far too intelligent to fall for the trap Uryu fell for, and although this has yet to be shown, I imagine he probably shared Soken's ideal of peaceful coexistence between the Quincy and Shimigami on some level. I have to imagine he'll enter the fray eventually, most likely fighting against the Wandenreich, not to defend the Shimigami, but because they would be a common enemy, for the reasons stated above, as well as to try and save Uryu (not to mention the fact that the extent of his powers, not to mention the abilities of the Spirit Armor haven't been fully developed upon). Admittedly, I could be wrong on several of my points, but only time will tell.
