Hiyakawa can't understand what Mikado is feeling. And for his part, while Mikado recognizes how deviant Hiyakawa is, he just can't cut ties with him.
In the middle of all this, Mikado is as good as kidnapped by Sakaki and taken to Erika in a car. Erika asks a bewildered Mikado for help with her homework, as though the situation were quite normal. As Erika works on her homework, she tells Mikado about the mysterious man who employs her and about how her powers awakened.
The vague emotion I felt
الشعور المبهم الذي شعرتُ به
Dieses vage Gefühl ist wohl …
Estos sentimientos
tan confusos que tengo
Estos sentimientos
tan confusos que tengo
Ce que je ressentais confusément
La sensazione che avevo vagamente provato allora...
A emoção que eu senti de forma meio nebulosa...
В её словах я 
почувствовал смутное желание.
