You always get letters, and the person who comes often to deliver the letters is..

Fukuro Shiro. He's your delivery boy! He comes to deliver all your letters and things.

He is an owl, he has an owl on his shoulder, called Eru. A male owl.

Today you were going to receive your letters.

You were going to see Fukuro, a young man, with golden, piercing eyes.

Intimidating as a real savage owl, in the wild.

It was winter, and you heard someone knock at your door.

It was him!
