Looks like nobody on these forums knows anything about this game. It's something like mix between RO2, WoW and ROSEonline. It looks so interesting, just like I was imagining RO2 in the past.
Animations are totally awesome. Characters are kawaii and the gameplay looks very interesting. "Shooting Cannon" like in SNES game Seiken Densetsu 3 caught my eyes. This game looks just sooo good. I hope it'll be in english soon.
This game is currenty in CB in Japan.
