I don't get how they went to "she's a genius!" because she knows letters when she is five. FIVE! Also, she didn't die from studying, she died from being an selfish immature idiot who ran away from home. The heck is she about "I won't die studying this time!"
I think it's also a hint that Tokio's story is happening in the past how they are all serviced by robots. Hell, it was even the cover for the chapter. It was said (but probably heavily distorted) how robots used to be really common and served the humans in a bunch of different ways
I wonder if maybe Tokio willed herself into someone who could have a baby after seeing those babies with the frog girl. Them going to see babies and then Tokio getting pregnant doesn't feel like a coincidence
