Synopsis
On the way home from school, I found a crane caught by a leg-hold trap in the park. ......

Why is there a wild crane in the park? What's more, even though it's in the city, it's a leg-hold trap !? I was upset by the unnatural situation, but the crane seems to be really in trouble, and it screams sadly, "Kuu ...".

The scent of troublesome things popped up, but I helped the crane anyway. Then that night, a beautiful girl named "Tsuruko" with a bandage on her leg visited my house and said:

"Would you like to stay here?"

…… After all, this is the development !?
