to reply to ur question, if u mean the potion to put her in the heat, u get it by interacting with the candy machine at the archdemon's stall. u can either pay money or pay through salmons which u get when u throw a bomb into rivers. its a pink color candy. as for th scene, go bathe first > finish the shampoo (shud be 0%), > let imouto go shower > select option "do nothing" > she will call you > use the interaction buttons and ensure u select "call her out" to call her out of the bathroom. when she walks back in after u hand her the shampoo she will trip and fall and ull get this scene. hope this helps
