Shibou Yuugi related Shower Thoughts and Theories. (plural)

Haven't read the LN, only read Manga (Kept With since Chapter 1's Fan-Translation) and Watched Anime (up to Cloudy Beach)
So most of the stuff stated will be random shower thoughts/theories related to Shibou Yuugi. I don't expect answers but It would be helpful (in more theorycrafting). so:

1. Is the preservation treatment still active post-game? Like we know Yuki goes to school (this was mentioned I think post-Candle Woods in the Manga?). So like imagine a spin-off/fanfic of Yuki getting into trouble or just tripping and then suddenly getting a white cotton-like substance blocking her cut
2. Theory: There's two Death Game Divisions. Female and Male. It's just the Female Side is popular due to appearance and clothing. The Male side might just be men throwing hands each combat focused death game or something.
3. Shouldn't Yuki Sorimachi and other Veterans be rich? Like they make money off of participation in death games and it's likely sponsored/paid by the audience
4. Audience might just be like a bunch of rich people. I don't think the common folk would know that much of the Death Game. Like back to School-Yuki, I don't her teacher would know about their student being in a death game unless they find out through like hidden links or invitations to watch. Bonus: I'd reckon Yuki's school is Co-Ed, just an assumption
5. School-Yuki again, but do you think Yuki also wakes up late for her daily non-death game life. Then again, how does Yuki explain her "absences from school" if she goes out for a Death Game
