Temporary Guardian

At the request of an old friend, the protagonist goes to Japan to take care of a thirteen-year-old girl!

Although this little girl has a difficult personality and is extremely unlikeable, it is still a very simple job—just looking after a child for one month, nothing difficult.

But as all kinds of strange things happen, the protagonist never expects that merely being a temporary guardian will actually drag him into the great disaster that occurred sixty-five million years ago.

Life really is full of surprises!
