Even though it’s believed the letters are coming from Okita, Shinpachi's response letter turn out to be a big hit. Urara is happy her older sister has received a response to her letters. But her older sister confesses that she sent Urara's picture with the letter. And it looks like both Shinpachi and Urara sent someone else's pictures with their letters!
I'm so happy that you're concerned about
my sister as though she's your own sister.
Me alegra que te preocupes por mi 
hermana como si fuera la tuya propia.
Fico tão feliz de você se preocupar com minha irmã como se fosse sua.
