So I DON'T need to buy the new blood character costume pack for them for it to be in LR
OA5 right? Please let that shit be true so I don't need to waste more money.
Sorry, I don't understand what you meant for "new blood character costume pack" XD
By the way if you meant outfits as Marie Rose Nurse, Cheerlader Nyotengu, Santa Phase-4, etc.... the answer is that you have still to buy them (or at least, so far they weren't included in the TGS demo).
When I talked of base character DLC, I specified even the exact outfits (C1-C4 for Marie Rose, etc...) just for avoiding this misunderstanding: in the demo were included the outfits for MR, Phase4 and Nyo that you get buying the simple characters without additional content, so all the outfits that you need to unlock playing the game.
