In order to learn more about Sensei's movements, Mikado and Hiyakawa make a plan to astral project into his house with the help of Mukae, Erika, and Sakaki. But they discover that Sensei's house was built on the site where the Palm of the Hand Research Society used to stand. Mikado recommends that they call off their plan out of concern for Hiyakawa, but Hiyakawa calmly replies "I won't remember. I never forgot."
Don't let Hiyakawa swallow you up.
لا تدع هياكاوا يبتلعك
Lass dich nicht von ihm erschüttern.
No te dejes llevar por él.
No te dejes llevar por él.
Ne te laisse pas submerger.
Non farti sopraffare da Hiyakawa.
Não se deixe engolir pelo Hiyakawa.
Не дай ему поглотить себя.
