栗栖 一史

A company employee in his twenties whose hobbies include watching videos and surfing the Internet.
He is a passive person, but when he meets Momoka on the Internet, he "flags" with a girl for the first time.
He watched the same shows Momoka watched as a child and as a student and working adult, so he is well versed in the topics of such works.
But then Momoka, whom he had met, suddenly disappears from his life.
A few months later, he finds a "live video" of a girl who looks just like Momoka on a certain backstage website.
