Yapool's dimensional trap sent Ultraman Ace to a world where no Giant of Light should exist.
This is Runeterra, home of League of Legends. There are no Ultramen here, only war, magic, and countless eyes fixed on him.
Ezreal, Akali... Taking on the human guise of Seiji Hokuto, Ultraman Ace comes into contact with them and gets caught up in all sorts of strange events. But his sense of justice as an Ultraman never changes.
Meanwhile, Yapool crosses dimensions as well, bringing deadly super beasts and determined to kill Ace.
Good and evil will clash in the legendary land of Runeterra...
“Children, never let your hearts of passion fade. Help and care for the weak; everyone under heaven is a friend. Friends may misunderstand one another or even disagree, but those things are insignificant. Don't give up on friendship. That is my final hope for you.”
