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."
After you use your power, you always 
become as defenseless as a child.
دائماً ما تصبح بلا مقاومة كالطفل
بعدما تستعمل قوّتك
Sie sind immer so wehrlos,
wenn Sie Ihre Kraft eingesetzt haben.
Después de que usa su poder,
siempre queda indefenso como un niño.
Después que usa su poder, siempre
queda indefenso como un niño.
Après avoir utilisé vos pouvoirs,
Dopo aver usato il vostro potere,
Depois de usar o poder, você sempre
fica indefeso como uma criança.
Когда вы используете силу,
вы превращаетесь в беззащитного ребёнка.
