A great post, Hai!  Though, I would like to point out that Ren had walked up to Tsukihi and Erica and asked to sit with them.<br/><br/>Other than that, Tsukihi is very fun to read.  <3<br/><br/>EDIT:  Though, it seems that Tsukihi is rather deep in her thoughts, so it's reasonable that she may not have even noticed or heard Ren.
