Some people are just...er... I'll be nice and not say it. Those comments about why Akatsuki make herself look like a child and was upset that Shiroe didn't chase after her, are annoying. I thought I was very clearly stated that she looked like herself in both as well. Naotsugu even teased her saying she should have done that in the first place (because of course everyone should make their characters look like themselves upon creation and even use their first names XD ).

It was a rare potion. Maybe Tet didn't know about them, couldn't get one, or didn't care (or was happy) about being a girl. Once she got back to Akiba after the raid, she would have definitely had access to the lesser potions made by the Roderick firm (if not before then) but she sticks with being a girl for whatever reasons. By that point she had been a girl, and changing, for over 6 month. At that point she had a choice and stuck with being a girl. (I still think she might have developed a bit of a crush on Nao).

The novel did say that there weren't that many people on the Japanese server who cross-played due to the voice chat since it was hard to hide your gender when you spoke (which was why Akatsuki was a silent assassin, which was something that stood out about her). The percentage of gender crossed people is probably lower in E.T. world than in usual MMOs. There was at least 4 known people - the two girls turned back to girls but the two boys stayed as girls.
