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.
So that no one can turn 
your curses back on you.
كيلا يقلب أحدٌ لعنتك عليك
Así nadie podrá devolverte la maldición.
Así nadie podrá devolverte la maldición.
Ainsi,
personne ne te maudira en retour.
Per evitare che altri possano maledirti a loro volta.
Para que ninguém possa virar
maldições contra você.
Чтобы никто не обернул
проклятие против тебя.
