I need help, I'm stuck at the point where the day is 4/18 and it says "Days until Expulsion: 14" and the objective as Steal Kamoshida's Heart and Find the Treasure, I'm stuck. I can't get past this point, I keep on losing &amp; going back to the safe room I last went to. I'm playing on normal difficulty &amp; mainly stuck cause I used all my SP and i dont have enough to do anything aside from HP using skills. what should i do?
