From ancient times to the present, everywhere in the vast universe, suffering has never stopped taking away the smiles on people's faces. However, people have never stopped imagining and practicing for a better future.
Sixteen years ago, the returned Ultraman, one of the six brilliant Ultra Brothers, crossed many multiverses and fought an arduous struggle with Emperor Knuckle and his legion. Finally, he fought to the death with the Emperor and his monster EX Black King in the Earth Star City, and both fell into a long sleep.
However, the crisis in this universe is far from being resolved. The dark power of Nakor overflows, eroding the creatures on the earth like a plague, depriving the infected of their reason and turning them into monsters. The rest of the evil ones are always ready to make a comeback and launch the largest invasion in history against the earth. In order to deal with the dark threats from the vast universe, and even more from mankind itself, mankind has formed a defense team called Monster Fight Team, or MFT for short, that is dedicated to fighting against monsters in space.
At the same time, the new hero, Ultraman Arc, will inherit the light of Guiman and stand on the earth again!
Purpose: The endless longing and imagination for a better future inspire countless people to rush towards the seemingly unreachable tomorrow.
