So, anyway. Day of Amy. We just saw a cat near the ice cream shop. Not sure if the Amy incident happened before or after school. Today's a Friday, and it's still early morning. (Will ignore the ice cream parlor being open at 6 in the morning. Open 24 hours, right?) Since there's nothing in the provided options about panicking and rushing to intercept Madoka and Amy, I'll assume it had to be in the afternoon.
Anything stressful on sanity is to be avoided. We've made it back up to 189 after a night of sleep. If we don't do anything awful today, we might be back up to 300 by tomorrow! We could almost pass for normal!
Ohhh.. I notice that going to visit Yuuko is an option. I'd like to talk to her about the possibility of something to help us bring our friends along with us on our loops. However that's a long trip without a car ride, and MikiMom is in SAO.
Anyway, if we're going to go after Amy, I'd go for something like:
[X] Go investigate something.
-[X] Search for Amy. You saw a black cat near the ice cream parlor. Was that her? You could probably get a bit of fresh cream and lure her with that.
-[X] If it is, take the cat back home with you. Go back to studying (at least til Sayaka wakes up).
Avoid using magic (don't stress grief or sanity), because we should be able to manage with completely mundane methods.
