heres the outfits i currently have im missing the cheer and recolors of other outfits
Honestly no clue, I haven't touched this game in a couple years. I would assume there is something specific that you're supposed to do in-game. Considering the icon is there but it is still locked, it must be obtainable somehow. Either that or the game is just bugged. According to the single review on dlsite, some events are actually bugged so maybe. There are also some events that can only be activated by literally doing nothing. Some scenes are specifically started by the heroine, and not the player. I read through some of the Steam pages and people were complaining about similar issues... back in 2019 when the last updates were made.
My recommendation, move on to something better. Virt-a-mate is worth every penny, (VR and desktop) despite the necessity to create most of your own content. But there are still far better VR games out there opposed to this one.
