I wanna see the blank stare on Moyako's face when Aki and Kasumi start dating.
She'd probably spin it as a ploy by Aki to make her jealous.
Or if she really is a brocon, she'll probably freak out.
Kasumi is their friend, so I think the last one is the least likely.
If it weren't a oneshot, I'd like to see the summons come more naturally. I understand bringing them all at once for this, but I'd like to get to know them one on one in this hypothetical. The concept of a hard isekai is pretty novel considering everyone gets cheat skills. I'd limit it to...
There should have been more conflict before the revolution. He should have gotten angry at her, then they talk things out and she starts seeing a therapist to deal with her mental shit.
Maybe then this ending would be deserved.
