CharaExpo USA is still a relatively new convention but with some backing firepower it is poised to become a must-visit event for Bushiroad fans. They've announced not only BanG Dream's Roselia but Raise a Suilen as well.
I didn't go last year because it was down in Anaheim and I had work-related obigations but this time I think I can make the journey. I've been told by friends that it's an incredible value for the price and I'll believe it. At $30 for both days you get not only the concerts but a slew of other Bushiroad-related things. Guys beating each other up in the squared circle? New Japan Pro Wrestling is there for you. Card games like Cardfight!! Vanguard or Weiss Schwarz? You're in luck. How about the games BanG Dream or Revue Starlight? They'll be there too!
If you like Bushiroad you'll be well-served by CharaExpo USA.
