A few days later.
At a logistics transfer station in Osaka.
A tightly packed parcel was lifted by two couriers and placed onto the delivery truck.
"This thing… huh, so heavy! What on earth is inside? Feels like this package weighs as much as two adults combined."
The couriers placed the package inside the truck compartment, then glanced at the shipping information attached to it.
The sender's line read, Rin Iijima.
The recipient's line read, Yoshizo Itakura.
As the delivery truck started up.
Inside the compartment, this package seemed to emit a slight noise.
Ding-ling—ding-ling—
The next "Waltz of the Little Dog" would soon begin playing somewhere at the Itakura family's home in Osaka.
