Tập 7: Nanaka trở về tuổi sáu sau khi ngất xỉu trong chuyến đi Kyoto cùng Kenji và Nenji.

7

Nanaka returns to being 17, but continues to hang out with Kenji during the trip to Kyoto. She does not care that her classmates do not like the old Nanaka, but when she overhears Nenji mention similar annoyances to Amemiya, she is saddened and escapes to one of the Kyoto temples. Nenji catches up to her and they talk about being grown up. Nanaka falls faint but when she wakes up, she is six years old again. (Source: Wikipedia)
