Takeru's trip back to his original world concludes after an encounter with his childhood friend, Sumika. After his return, he learns about the enigmatic Yashiro Kasumi's mysterious past.
And that's what nostalgia is.
.هذا ما يعنيه الحنين للماضي
Das ist unsere Erinnerung.
Así nace la nostalgia.
Así nace la nostalgia.
C’est ça
qu’on appelle un souvenir.
E quello si trasformerà in nostalgia.
E isso é uma lembrança.
Это будет воспоминанием.
