Intro
“—Here they come! Everyone, stay back!”
A desolate battlefield echoing with sirens. Against a massive swarm of enemies aiming to break through the 47th Defense Line, Karuna Hojo kicks off the ground and steps forward. Clad in a silver and black high-tech combat suit, her blonde twin-tails fluttering in the wind, she raises her massive greatshield toward the sky and shouts nobly.
“—Manifest! ‘Absolute Boundary Field (Noblesse Oblige)’!!”
An invisible equilateral triangle barrier glowing blue expands, swallowing the surging enemy horde whole. However, above them—circling as if to cover the entire defense line—was a massive shadow that shouldn't exist at a B-Rank post. The giant floating organism, A-Rank ‘Sky Whale.’ The gravitational waves and wide-range shelling from its colossal body strike the apex of the barrier directly. BOOM!!
“Ngh...! Kh...!!”
