He didn't know how to respond, so he just vaguely "hmm"ed.
Then, Kamigawa's mind echoed with the words Mr. Takiguchi had said earlier at the Takiguchi household—
"Since childhood, I was more prone to illness than other kids my age, and my grandma would often take me to the village shrine to pray for blessings. Perhaps Grandma's prayers really did have an effect, since despite being sickly, I still managed to survive to this day."
"On the way to the shrine, I was led by Grandma's rough and warm hand. When I got tired, I could lie on her back and act spoiled… and on the way home, I could buy a persimmon for ten yen."
"Grandma always cut my hair herself in the yard, the hairstyles were plain but adorable."
"..."
Mr. Takiguchi must really miss and cherish those days he grew up in Kamiyagawa Village with his grandma by his side, right?
It seemed that in Mr. Takiguchi's heart, his grandma was probably the closest relative he had in the world.
