Rio and the others have traveled to the royal capital of the Kingdom of Karasuki with the village's annual tribute as guards. With their duties fulfilled, Rio and Sayo head into the castle town. They enjoy a meal and are doing some shopping when wandering warriors attempt to abduct a young girl. Rio jumps into the fray and easily defeats them, saving the girl. Her name is Komomo and she's the tax examiner Hayate's younger sister.
Hayate's father Gouki receives a letter from Yuba. What he reads astonishes him and he and his wife, Kayoko, visit the lodgings where Rio is staying. They reveal to Rio that they once served his mother, Ayame.
I'll be back soon. If anyone you 
don't know comes, you stay inside.
.سأعود عما قريب. إن أتى شخص لا تعرفه فلا تسمح له بالدخول
Ich bin bald wieder da. Wenn jemand kommt,
den du nicht kennst, dann bleib hier drinnen.
No tardaré. Quédate adentro
si viene algún desconocido.
No tardaré. Quédate en casa
si viene algún desconocido.
Je serai vite de retour.
N’ouvre pas aux inconnus.
Io sto uscendo. Se arriva qualcuno che
non conosci, non aprire e resta dentro.
Eu volto em breve. Se alguém que você
não conhece vier, fique dentro de casa, tá?
Я скоро вернусь. 
Не открывай дверь незнакомцам.
