Teppei Arashi was once a Designer Child inhabited by the alien soul known as 'Albion', until a fateful encounter with Daichi Manatsu ignited something profoundly human within him. Determined to claim his own humanity, he made the irreversible choice to destroy his soul's core, severing his alien origins in exchange for genuine emotion and belonging. Now a member of Globe, he takes to the skies in a Nebula Engine to stand as Earth's guardian, forging unbreakable bonds with his allies and proving that the will to protect can transcend even the boundaries of one's own existence.
