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."
P-Probably not. From what we've seen, 
it looks like a normal house.
لا-لا على الأرجح، يبدو منزلاً عاديّاً مما رأيناه
N-Nein. Sieht für mich
wie ein normales Wohnhaus aus.
Lo dudo. Se ve como una casa normal.
Lo dudo. Parece una casa normal.
Ça m’étonnerait qu’il y en ait un.
C’est une maison banale.
C-Come potrebbe esserci?
Acho que não. Pelo que vimos, é uma casa normal.
