Urban: A Celestial Object Has Come to My Side

In a world parallel to Earth, Blue Star.

One morning, Kitagawa Hidehiko, an ordinary high school student with nothing special about him, wakes up to find a girl lying beside him.

She even says she's been following him all day. Then why didn't he know?

Then she says she's lost her memory.

How could this happen? Doesn't that mean he can't kick her out? Does he have to take her in?

Little does he know that the decision he makes that day will turn his world upside down.
