Defense Sector 3.
Along the coastline, the Steel Legion stood like a silent, iron-colored dam, ready for battle.
After a moment of dead silence, the sea surface suddenly erupted about five kilometers from the shore!
A colossal black shadow, wreathed in tens of thousands of tons of seawater, shot into the sky like an awakened abyssal sea god.
The King of Heart-eaters!
It was over thirty meters long and covered in deep blue scales. Each scale was as large as a door panel, shimmering with a faint blue demonic light as if forged from water element crystals.
On its bone-spiked head, three pairs of deep red eyes swiveled. Two pairs burned with madness, but the topmost pair held a glint of intelligence.
"ROAR—!!!"
It opened its massive maw, large enough to swallow a fishing boat, and let out a roar unlike any sound a living creature could produce.
