Hello, please help me, anyone who has completed the game? I have managed to reach the final chapter of this game and I am having trouble completing the final chapter. After I opened the secret passageway (near the old tree) Mayu was captured. Then the ritual was about to begin, I followed her in the huge house and went underground. There I found the Hellish Abyss. Mio witnessed the past ritual and an explosion happened. Only after then a huge ghost appeared and blocked the entrance to the Hellish Abyss. I was unable to escape (because for some reason the exit was also blocked) and when the ghost attacked Mio, she died and the game ended. How can I save Mayu and defeat the ghost??
