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...
A single grain of unhulled rice can 
grow into many times that amount.
حبّة أرزّ واحدة غير مقشّرة تنمو بأضعاف مضاعفة
Ein kleines Korn

On dit que c’est un jour de chance
où un seul épi de riz
Un giorno in cui un grano di riso si moltiplica 
in decine di migliaia di chicchi,
Um único grão de arroz sem casca pode
dar esse tanto de outros grãos de arroz.
