In the martial arts tournament held in the Aradisia Kingdom, ruled by King Alphecca,
you were working as an operator for the Heroes' matches.
Suddenly, you were sucked into an unstable portal!

You arrived in a world where "magic" is used like a daily occurance.
While searching for a way back with a Music-loving Ninja and a Former-Pirate Swimmer,
a group calling themselves "King's Messengers" appeared...
and you were appointed as the "Hero" to save the world!?

In an unknown world full of various mysteries,
you gather allies like a Wizard from the Endangered World
and a Blade-obsessed Blacksmith,
and embark on a journey to stop the universe's destruction!

Can you save the fading parallel universe, the "Endangered World",
and safely return to your original universe—?
