Keima was under the impression that he had found a potential route where he would cheer up the broken-hearted Chihiro, but she's already found a new love!?
Keima snaps at the absurdness of the real world, but he is beaten down by Chihiro's counterattack.
That is when Keima is helped by a previous conquest, Ayumi!
Ayumi manipulates Keima and Chihiro into cleaning the classroom by themselves.
Eventually, Keima finds himself caught up in a certain event...
After all, you filled the 
emptiness in Ayumi's heart!
¡Después de todo, llenaste el espacio 
vacío en el corazón de Ayumi-san!
¡Después de todo, llenaste el espacio 
vacío del corazón de Ayumi-san!
Até porque você preencheu o vazio
 no coração da Ayumi-san!
