I'm trying to get a sense of what people use their kobans for after the recent update. I'm trying really hard not to spend real money and going broke trying to progress through the story, fighting bosses to get more girls, getting the girls in epic pachinko ×10, and the occasional upgrade for the affection scenes. My specialty is hardcore and I'm up to lvl 79 in The Juy Sea about to acquire Abraël. Also, I already leveled up all of my hardcore girls (Bunny, Ankyo, Arcana, Cupid-Chan, Regine, Loving Justine, Lupa, Loving Arcana) but I got plenty of 3 ⭐ charm and know-how girls left to upgrade. How should I progress further?
