I don't think resetting Touya would really help much. If he's suffering from a lack of direction with Yukito/Yue not in the game, resetting him will only kill the CR he's already got. He'll still miss Yukito(/Yue) and want to go home, even if the feeling's lessened.
I'm not quite sure what would work for him, but maybe trying to work around possible plots with castmates or his other CR would be a good start.
Touya aside, it's great to see your other characters around more often, and I think you've improved a lot with consistency when tagging back.
The one thing I can think to crit right now is the generic-ness (?) of some of your tags. I often find it difficult to reply to your characters' tags, because they will give generic, short replies that don't give me a lot to work with. Obviously characters like Touya or Takeshi would tend towards this, but it seems to happen too often, even with Hideki or Keiichi who should be more sociable. It makes it really difficult to get threads going, and I end up feeling you want to close up the threads as quickly as possible, which might not be the case at all.
