I always thought that Jacket Girl disguises herself as a boy to go unnoticed in the DiPP story.
But I keep thinking, how does she hide her long hair?
in DiPP's story, she has long hair, so it doesn't make sense that in the story she has short hair and over time it has grown out, she had long hair from the beginning of the story.

The person staring at a mirror should be jacket ko as a man due to the statement "the only girl of the 7 honest men"
It's implied that after he killed himself he was "reborn" as someone from gensokyo as a girl
