For Itsuka's birthday, Nagomu uses his "Going Somewhere Together" ticket and takes her to Hirakata Park. While out with Nagomu, Itsuka's remembers when she went to the park with her father.
When they get back to Ryokushou, they find a wagashi cake and birthday party for Itsuka waiting for them.
Itsuka always seems to be chasing after the shadow of her father. Concerned, Nagomu comforts her. And in reply to Nagomu's words, Itsuka...
If you're lying, I'll make 
you swallow a thousand yokan.
إذا كذبت، سأجعلك تبتلع ألف يوكان
Wenn du lügst, stopfe ich
dir Tausend Yuzu-Yokans rein.
Si me mientes,
te haré tragar mil yokanes.
Si me mientes,
te haré tragar mil yokanes.
Si tu mens,
je te fais manger 1 000 yôkan.
Se dici le bugie, 
ti faccio ingoiare mille yokan.
Se você estiver mentindo,
vai ter que engolir mil youkans.
Нарушите обещание — скормлю
вам тысячу ёканов.
