Beyond the Western Mountains lies the largest and most bustling human stronghold.
Its name is "Yui City."
Yui City spans three thousand miles, where no common passersby are ever seen.
Towering walls reach into the clouds, as unyielding as iron. Flanking the city gates are two colossal mechanical beasts.
These are the guardian beasts of Yui City.
On this day, the sun was bright, the wind gentle, and people went about the daily routines of their lives.
Suddenly, the earth trembled, and a rumbling sound echoed from the horizon.
Those standing on the city walls looked westward, only to see the massive figure of Chaos emerge within sight.
The boundless energy of Stepping into Immortality reverberated across the Firmament.
"Look quickly, what is that?" someone exclaimed, pointing at Chaos in alarm.
"A monster beast is attacking the city! Prepare for defense!"
"Hurry, activate the guardian beasts!"
