Itsuki Tachibana is a male character and non-hostile spirit in Fatal Frame II: Crimson Butterfly. He is one of the souls trapped within All God's Village. Itsuki meets Mio and Mayu Amakura after they find themselves trapped inside the village. He first gives advice to Mio after she lost track of her sister, letting her know the way to reach the Kurosawa House, where he believes Mayu is headed. During the entire time that Mio and Mayu speak with Itsuki, he addresses them as Yae and Sae Kurosawa, the last twins meant to undergo the village's secret ritual. His help is limited, however, as he is only able to give advice from within the storehouse he is locked in.
