It's the last day of the school festival. Naho and Kakeru have promised to watch the fireworks together. However, just before they start, Ueda-sama gets in Naho's way. Will Naho get to experience watching the fireworks with Kakeru like her future self did?
If you can't do it, then show me 
that hairpin from yesterday.
Wenn es nicht geht, dann halt
die Haarnadel von gestern.
Si no puedes ir,
muéstrame el pasador de ayer.
Si no puedes ir,
enséñame el pasador de ayer.
А если не можешь —
 покажи мне ту вчерашнюю заколку.
