I mean chapter 28. (ch 27 is the latest one)

Insecure Herami Sisters is also ending, at chapter 27, but it's on hiatus next month, so it'll be in the issue after that.

I typo'd the Japanese title - it's Netsuen.

There's another cameo scene from the manga which I'm sure the anime will adapt, but now I'm thinking there's a real chance it will be somehow expanded with an additional character.

This one-shot, Ashita no Sora wo Miru Hito Yo, by the same mangaka is about a lesbian meteorologist in 1945, and marriage equality now. It was released close to the 80th anniversary of Japan's surrender.

Title is あいすくう人 but I can't decide how to romanize it because I think it's wordplay on アイス食う and 愛掬う, and maybe even (同舟)相救う.

At 3:42 it's her saying "Kuzushiro desu, yoroshiku onegai shimasu." Her contributions to episode are kind of scattered. At 5:53 Natsuyoshi invites her to answer a question about where a line came from.

Then someone thought it was genuine and tweeted in 2011 about it being unfair compared to fujoshi. That went viral with people reacting to it, such as to say they'd not heard of it. That spread awareness.

Gist of it is that himedanshi (princess boy) existed as uncommon gay slang. Some people joked about it could be a term for boys who liked yuri.

The apparent origin is weird. A Japanese investigation into it: posfie.com/@babanshika/...

It wasn't astroturfed. The magazine doesn't use those terms.
