Honestly one of the most unintuitive part of the game.
Got to progress Ino, which means learning something from naruto which means having progressed every other girl enough.
Not to be a bother but I should have clarified better, right now I've already broke Sakura and Saurada and kushina, Naruto has the pigtails but he only tells me "just one word and I'll fuck you up", Ive progressed Ino to the point where I can fuck her and Hinata tells me to wait till night time but in the afternoon she says I have to train her more, but at night "I feel like I'm missing something for tonight's training" and currently I'm on the hunt rn but I want to finish Hinata. Overall I love your game mister Faust (or miss)
