@zubkoa I believe there is absolutely nothing that has to be changed for the cut content to be re-added, personally. None of the bath scenes should be excluded or modified, as most people understand that people in Japan bathe in public, and popular games such as Persona 5 do show it in-game, albeit with less story content happening in there.
There shouldn't be a problem with short characters either, as other games have content some people on these forums would find controversial. Blade & Soul have the Lyn, the childlike race, wearing swimsuits and other skimpier outfits. Tera's Elin have been mentioned many other times in the forums as well. And if we go into more obscure games, Wonderland Online had actual children playable (no 1000 year old lolis), as well as a story illustration featuring a child party member, Xaolan, completely naked, playing in a river with another nude party member. None of this got censored in the NA server, and it supposedly got a T rating.
PSO2 is far from the worst when it comes to content in online games, so there's no reason it should be toned down.
