Kaoru, a friend from the piano class Ruli once attended, has gone missing. While searching for her, Ruli and the gang find a strange dent and her shoes. And as they continue their search, Hiro is suddenly asked a mysterious riddle.
Even if you want to go back
to your old life, it's too late.
حتّى لو أردت العودة إلى حياتك
السّابقة، فات الأوان
Selbst wenn ihr in euer altes Leben
zurückwollt, wäre es dafür bereits zu spät.
Impossible de faire marche arrière
une fois lancé.
Mesmo que queira volta a sua
vida antiga, é tarde demais.
Если захотите вернуться
к прежней жизни, будет уже поздно.
