1. It's not "VIP", it's "WIP", wich means "Work In Progress".
2. Sakura house is acessed by this button on the top right corner on the map screen. I even added a icon on last update.

Well, let me tell you a quick story. At first I was planning on giving ALL characters the option to be futa, one of the reasons I chose the Naruto/Boruto world was the Transformation Technique! Then I started making the game and realized the insane amount of work that would take. Especially for the main duo (Hinata/Himawari). So I'll definitively try making side characters have some option to turn Futa (Like Tenten in this last update). But can't promise or prioritize it now. I'm really trying to make this a full game, so I can always come back later and add futa for everyone then.
