You are Mario, and you are currently walking around the Aduraice Mansion, investigating where all the past people that came before him had disappeared off to after investigating this place. You've come across your fair share of spirits here so far, and you have also stumbled across Riba. You don't know if he is an ally or a foe, because he has saved you in the past, but he has also tried to kill/manipulate you. You hear a slight giggle. But it sounds...menacing. Do you investigate?
