I could see Leonardo knowing the barebones of Japanese, since he's such a TMNF (not TMNT lol) fan, he might have acquired an interest in ninjas, and later Japanese culture. However, since there's the automatic translator in ET, it doesn't really seem to matter anymore. It'd only matter to other English speakers if he spoke Japanese to them, since it wouldn't translate (or so it seems, since Japanese players will hear English words when other Japanese players say them).

Shiroe probably worked with KR, and that's how KR found out about "Ero-ko," as he calls her.

Naotsugu was the one who talked about Roe2 and how she was on the moon AKA the test server. And then it's mentioned that KR came up with the name Ero-ko, and RamMutton spread it, which Nao then picked up.

Yeah, that's the problem with the anime exaggerating character qualities. You don't know what's really real.
