Chitose Tachibana is a hostile female spirit in Fatal Frame II: Crimson Butterfly. The younger sister of Itsuki and Mutsuki Tachibana, Chitose was not a twin and knew very little about the Crimson Sacrifice Ritual nor did she understand where Mutsuki had gone and why Itsuki's hair had turned white.
Chitose had poor eyesight, and was often frightened of strangers, frequently hiding inside of closets when they came to her home. Because of this, Itsuki gave her a bell to wear, so that he may know when she was in danger and could go to her aid. Before leaving to help Yae and Sae Kurosawa escape the village, Itsuki gave Chitose the key to his room, with instructions to give it to his friend, Ryozo Munakata. When Ryozo came, however, Chitose got so scared that she hid, unable to give him the key. After the escape attempt, Chitose blamed Yae for having Itsuki wrongfully imprisoned, not understanding how much he wanted to help them escape.
When Sae's ritual failed and the Repentance occurred, Chitose hid inside of a cupboard to escape the coming darkness. She became trapped inside, however, and panicked, scrawling "help me" on the walls and frantically calling out for help from her brother. In the end she either starved to death or was swallowed up by the darkness.
Chitose wears a distinct crimson kimono, with pale gold butterfly designs, further alluding the game's theme. Like all ghosts, she appears very pale, and she keeps a sad expression on her face. Chitose also wears a bell on her right wrist, which chimes whenever she is present in the room, even while she is hiding.
