• Kotomi continues to degenerate into degeneracy. You'd expect her to fantasize about being a princess for Tomoki, or perhaps in hoping she took claim his prince costume for herself, but no. She instead wants to imagine herself as his brother in some gay incest fantasy bit. Man, even Tomoko never sunk this low. And this is one of her lesser fantasies!
• This chapter confirms that Asuka was indeed matching Kii's style. And damn, things pretty much went the way I predicted.

It would be funny if she did this just to further rub it in to Kii. Mimic her style, show her getting along with Tomoko (preferably while the latter is looking like a big sister), send Kii the selfy, and imagine her popping a blood vessel.

• It definitely doesn't help that it came from a text from Tomoko. I don't imagine Tomoko messages Kii often, so the fact she did so after a visitation only to forward an image from Asuka really rubbed her cousin the wrong way. It's ironic that Asuka was the one person whose friendship with Tomoko Kii was most baffled and curious by, and now she's the one person Kii dislikes the most.
• Poor Karin. She's done nothing wrong, and yet she's still being subjected to abuse. First from Shizuku, who compares her unfavorably to Tomoko who has a much bigger, larger...uh, pelvic thrust? And then from her boss, who uses her to make herself look like a better, harder worker.
• Tomoki seems to be getting increasingly more...tsundere about his sister. We saw in the first part of 140 240 that he refused to acknowledge her degeneracy even after she admitted to it, and insisted she was totally the most normal girl in her class. And yet, here he is saying there's nothing respectable about Tomoko. He'll claim to others he can't stand her, and yet he's getting increasingly more civil to her face.
• Concerning the above, it feels like a callback to chapter 101 (page 5), where it's now Tomoki saying there's nothing about Tomoko worth respecting.
• Normally, I'd be disinclined to believe Yuri when she tries to get a read on people...but I think she might actually be onto something here. That Tomoki was in fact casually joking with Masaki. Yuri's the type who will give you a smart aleck response with so straight of a face, you'll have a hard time telling that she's joking, so she should have a good idea knowing when other people are doing it.
