It's good to see there is a small trace of humanity in her, she technically was raised by her for a long time after all until she stopped caring.
And even if she has a plan, I feel like their confrontation will actually be a knife battle.
Is FOA her sister? Sure looks like she might be, at the start I thought it was funny they didn't know her name, but it seems to really be plot relevant.
No, please Tama, fight!
She's smart and a pro VN player, I'm sure she can come up with something to make this convenient for herself too, though it's hard to just say she wants to move there as well.
Honestly, MC is really fun in this one, been a while since I saw one with so much personality. Makes sense because she and her thoughts kinda have to carry the manga for the premise to work.
The name could actually be Isaac considering Isaac Asimov.
Though, what if the twist is that she's actually part human, like a cyborg? Just with no memories of being one, so she just acts like a robot and calls herself a human.
