Such a good chapter. It's nice to see that Tomoko has regained the sisterly respect Kii-chan once had for her, even if she did become a little warped along the way. I'm not sure if Tomoko even intended for her story to be symbolic as it was but I though it was another great example of how Tomoko can sometimes be surprisingly poignant without really trying.
Also while it's true that the manga is nearing it's endgame , the rate they're going at still means there's a lot of content left. We still got Summer Break, the cultural festival, Valentine's, White Day, exams and some other goodies to look forward too.
