The night sky always seem to leave those who gaze upon it mesmerized and amazed by the beauty of the heavenly bodies that can be found within. Knowing that these bodies each have their own names, stories and secrets to behold, Leo explores and studies these "inhabitants of space" as to satisfy his fascination. However, this fascination seems to be hereditary, as Leo is a descendant of one of the greatest astronomers known to man, Galileo Galilei. While in school, he soon finds himself within a dream-like moment as the sky darkened and was suddenly filled up with stars. A star-struck Leo then wakes up in what appears to be his house with new things, and new people, who are more familiar than he thinks.
