^ Okay, what if it was Laura who spoke Japanese instead? We believe that in I.S.A., everyone is either speak English or Japanese. Assuming everyone speak Japanese, this means Laura learn it somehow.
Also, Ichika not exactly stupid, just lazy. He was top student in his Junior High. And his problem with I.S. related subject is because he didn't started with basic and jump directly to the advanced subject. So, Ichika learning how to speak German is not that impossible.
