|“||I feel like I can't remember anything. . .||”|
Himiko was a patient at Haibara Hospital. After the Kiraigou, her Getsuyuu Syndrome progressed, and she began to wander, waking in strange places with no memory of how she got there. She imagined she heard strange music, and began to lose her memories.
When the normal medicines failed to improve her condition, she was subjected to experimental brain surgery, performed by Shigeto Haibara. However, these surgeries only sped up the progression of the disease and caused her to Bloom faster, thereby killing her.
- Himiko is one of only two ghosts in the game to show signs of this particular operation, the other being Yuuzou Takemura - these ghosts share similar attacks and are much more aggressive than normal spirits, causing more damage as a result.
- Himiko appears in Haunted House Mode in Fatal Frame: Deep Crimson Butterfly.
