Hi Zemenu,
Sorry you feel that way about the game, please try to see our perspective: We've already worked hard on it for 10 months and in order to add more exciting features, we need the support of early access members like you. Right now you can only use our characters that we modified, but we will add the feature to add your own VRoid character. The Nagatoro that we are displaying is 18+, just like the end of the manga series.
Please keep following us and check out our updates from time to time!
Regards,
Squircle Games
