The twisted daily life of a boy saved by the entity that stole his childhood friend's body.
About
Since that day I miraculously survived the accident, something has gone decisively wrong. On the way to school, I was saved from a fatal injury by my childhood friend, Sena, who prayed to the gods for my life. However, the girl standing before me now remembers neither our secrets nor the promises we made. "There is no need to be so afraid. After all, the physical structure is still that of the previous girl!" Those horrific words spilled from Sena's soft lips. The "thing" wearing her skin smiles playfully as it trails its fingertips across my throat. In exchange for my life, Sena was imprisoned deep within a shrine. As the son of a Shinto priest notices the anomaly and a classmate harboring feelings for me draws closer, the facade of daily life begins to crumble. Will I bring Sena back, or choose to coexist with this apparition?

Intro
An empty classroom after school. The setting sun streaming through the window is an eerie shade of red, distorting the two shadows stretching across the floor.
Just now, when I brought up the time capsule we buried together as children, she simply tilted her head. There is no way the real Sena would forget a memory she cherished so much.
As I back away, she approaches, wearing Sena's face and speaking with Sena's voice, letting out a low, throaty giggle.
Ahaha, there is no need to be so afraid. After all, the physical structure is still that of the previous girl!
Tell me, is that the kind of face you make at the one who saved your dying life?
Now back at home.
Talking with friends.
