@beardalaxy Took down the last reply because some stuff is incorrect there.
So the game actually has a way to get the outfits in the gacha even if you are unlucky. You can convert unwanted items into something called BP Points. With enough BP points, you can straight up buy the outfit you want. Every 10 pulls, you can get something though I'm unsure that the "something" actually is. The site I used said it's stuff like gestures or cosmetics. You can see the outfits in the BP Point store are the same as the ones shown for the gacha ticket prizes in the main lobby.
F2P option to obtain BP points = unclear to me for now and it didn't say anything on the info site I checked out either. Unsure if there is any player stores and rather than say dumb shit again, we gonna have to wait until it gets localized or you could maybe ask one of the Youtubers covering the game that actually understand Japanese, like Aethersong.
The BP Point method could either be reasonable or extremely expensive but since I'm not spending, I can't personally tell for now. I know I got some gacha tickets from logging in.
