In a Tokyo in the not too distant future a young girl studies deligently with ambitions of soon attending space academy.  If things work out just right, her future may very well be among the stars as well. And yet, every time she looks up to the stars there is a sense of melancholy in her heart. A sadness surrounds Asumi, as space exploration itself has profoundly impacted her life for as long as she can remember. But she is not alone...A young man wearing a lion's mask is always beside her. He speaks of the constellations and galaxies as if he they were like home. He knows what it is like to love the stars--slightly bitter and yet always so warm and inviting. Truth is he has gone through much of Asumi is just experiencing. And now in spirit he will forever be with Asumi guiding her on her path to space.
