I don't fully understand the second half of the 3rd panel, so I won't guess at it. Something about a robot named Nineball as a parody (homage?) of the movie, plastic model came out recently, go check it. The part that kills is 搭乗者, I don't see what it means in the sentence.

Fill it in as needed.

搭乗者 means "pilot", and "AC" means Armored Core.

No wonder. I've never played AC so I know nothing about it. Filled in the rest, fix as needed.

wow...
Cirno actually taught me something...

More like a professor of ⑨-ology. That and she got so sick and tired of that joke she studied like a mad fairy

And the resulting imbalance caused by a non-⑨ Cirno forced reality to brain-drain everyone else to compensate?

I'm one of those rare folks who doesn't really like Cirno. But I'll admit that trivia-smart glasses-wearing Cirno is ultra cute. *goes back to playing For Answer*

Obligatory.
