I play JP for the JP experience, re-reading the story and dialogue in JP, that's all
Somehow, the story and characters stick better in my mind. Maybe because my reading pace in JP is slower than in English.
Also I got Skadi with the free 10 roll on W/Weedy banner. Seems like my luck in not getting banner 6* carries over
Like whenever I get a 6* in my main, 70% of the time it's not the banner 6*. The reverse is true for lower rarity banner rate-ups lol
And I like Skadi but don't have her on my main orz, which is additional incentive to play my JP account
