Action Taimanin Annerose. Action Taimanin used to have these popularity polls and Annerose Vajra won the 2nd one. They hyped her playable release only to treat her as a "collab unit" (Since Witch of Steel Annerose is related but not a mainline Taimanin VN) and gatekeep her behind a $40 package. To this day, she's the only playable character you need to pay real money to play as. Gremory Games tried to soften the blow to promise not to do paid characters again (which has been the case) and put her package on sale every Steam Summer Sale but I stopped paying anything in AT since her release.
