Always cautious when there's love triangle appearing this late in a serie (Considering how Akina is engrossed in Kaede despite her denial, can't really see her going for another girl at this point, unless Kaede does reject her), but might be interesting for her to see a reflection of her attitude.
Also love how the "master" casually started a fight between aoxkuro and kuroxao fans just to ignore it right away XD. But yeah, kind of a bad choice for her to use kurocross, she didn't research Akina's interest well enough, or she would have gone for Prepure :p
