Una de mis escenas favoritas del juego y en japones como deberia ser D: One of my favorites scene from the game and in japanese audio how it should be D:
I like to think that Financier actually figured out that the Blanc on the left was the real one after the first question, due to her reaction, but she kept going on to tease her and see what she'd do.
Blanc: YOU MIGHT KNOW EVERYTHING I'M GOING TO DO BUT WON'T HELP YOU SINCE I KNOW EVERYTHING YOU'RE GOING TO DO *STRANGE ISN'T IT* Sticking to Sonic references
They sound like they aren't even trying to sound japanese. Why everyone like the english voices more? There's a good reason most people prefer subs over dubs in animes too.
None of them are truly better than the other - that's up for you to decide. For me, personally, I prefer the dub since I just prefer their voices overall.
