At the Séance Shrine, Iroha wrote her sister's name, Ui, and Yachiyo wrote the name of her former best friend, Mifuyu, on votive plaques. As if to confirm the truth of the rumor, Ui and Mifuyu appear, but they are twisted imposters of their loved ones. Iroha and Yachiyo are attacked by the fake Mifuyu and the master of the Séance Shrine, a Horse Monster, and find themselves in a bind that threatens to end their lives. Iroha's Soul Gem gets cloudy, making her slowly lose consciousness. What sort of transformation will she undergo?
I fit exactly in the empty space in your heart.
Soy el hueco que hay
en tu corazón, Yacchan.
Soy el hueco que hay en tu corazón.
J’ai exactement la forme du trou
dans ton cœur.
Riempio alla perfezione quello spazio vuoto 
che c'è nel tuo cuore.
Eu me encaixo exatamente
no espaço vazio em seu coração.
