Heh, well...in the case of characters like Theo, Alex and any others who have issues with the language barrier, ATLAS has a way around it.
Out of character, this is just because, while it could be amusing at first, it'll probably just cause headaches later on. In character, during the second invasion, several members of the combat forces got killed because they couldn't communicate with each other.
The solution? Candy that basically teaches the person eating it Japanese. Why not just develop candies for combat skills? Momoko's mother doesn't know enough about that. Why candy? Because Momoko was a little girl when they started development.
Also, um, GCR? This is going to be the first night of the invasion, so they wouldn't have been fighting anything last night. In hindsight, I didn't really make that clear.

I was thinking another page or two or whenever people are ready for me to timeskip.
Burn up, hurricane of justice!As long as it doesn't have pineapple on it. Pineapple does not belong anywhere near a pizza. Why would you defile holy ground like that? Why!?

So, just out of curiosity, why are so many people opposed to having their characters know what everyone else is saying?
Burn up, hurricane of justice!

Sooooo, as I understand it, there will be characters speaking Japanese. And my Theo only speaks English.
This will be fun
