When Kobato goes to visit Osanai at her home to invite her to eat candied apples, he learns that she has been kidnapped. Just as he leaves the apartment, he receives a mysterious message from Osanai and, with Kengo's help, sets out to find her.
I don't think I'll ever 
be able to forget you.
.لا أعتقد أنّي سأتمكّن من مسامحتكنّ أبدًا
Ich werde euch sicher nie mehr vergessen.
No creo que pueda olvidarlas jamás.
No creo que pueda olvidaros jamás.
Jamais je vous oublierai.
Non riuscirei più a dimenticarvi.
Acho que nunca serei capaz de esquecer.
Я вас никогда после этого не забуду.
