Volume 5: On a Rainy Day
Transcripted by schally
(taken from a dubbed version)

No dialogue. Momiji drips her fingers into water, studying herself in the mirror. Momiji sits on her bed, humming as she stares at the ceiling (she's humming Carnival Babel).

Momiji watches rain fall. Momiji sits by the bed and continues to hum. She takes a drink of water. She takes another drink, stares out the window some more and writes "Kusanagi" in the fog on the window.

At the end, we see a paper Kusanagi doll hanging from the window. Momiji is smiling at it.
