Big mistake...

Back when I was a real low level I remember once some level 200 got me into an S-ranked mission and it also had all rainbow drops. I thought nothing of it and sold most of the weapons I got, but I kept one or two of each. (All I got was a claw and a slicer)

Unless you're playing the Japanese version, there's no way you could have played with a player of the Japanese version.

Unless the "Japanese" person had his file converted.

Unless the "Japanese" person had his file converted.

Then he wouldn't be playing the Japanese version.
