In the library's anteroom, they find Natsuno's stalker Fujimaki Hotaru--her classmate Osawa Hami.
She and Kazuhito had once exchanged promises--that she would become an author and he would be her first reader. Having become an author, Hami returned to see Kazuhito. "Welcome home, Kazuhito-kun."
To become a real author, 
I need to defeat the real author
Para ser una escritora de verdad, 
debo vencer a la verdadera yo
Para me tornar uma autora de verdade, 
eu preciso derrotar a autora verdadeira
