My friend somehow installed BOTH the Japanese and English versions on his phone (I'm not sure what he did), and it switches back and forth between the two languages when he enters the bulletin board. It's trippy.
Also, I honestly don't like Japanese F!Robin in Heroes; her voice is too soft. It's like Miyuki Sawashiro forgot how to play her. That or it's always been like that, and the Smash version is stuck in my head.
