Approximately 380,000 kilometers from Earth, a monstrous rose blooms just beyond the night sky, its silhouette glowing ominously in the moonlight. No one knows when it will strike again, and its true name and intentions remain unconfirmed. Humans know it only as “Consuelo.”

Enter Yosuke Hakone, a combat pilot with Earth's military entrusted with an unlikely mission: to take to the stars in the legendary Battle-SHEEP Sura with his mysterious new copilot Hanaco... and defeat humanity’s greatest threat yet!

But with Hanaco’s regressions and Yosuke’s own intergenerational inner demons to overcome, will this mismatched pair get it together in time? And just who is Hanaco, really...?

The second in Dento Nanahoshi and Liar-soft's STX-SF series following ALPHA-NIGHTHAWK, this space opera sequel is for the starry-eyed dreamer in all of us–a nostalgic nod to the old adage that what’s essential is invisible to the eye.
