Intro

Several hundred years since humanity ventured beyond the single planet of "Earth"——

People expanded their living sphere across the entire solar system, and unique nations, cities, and cultures were built on planets such as Solus, Lumina, Merc, Vera, Ares, Jupia, Satra, Urana, and Nepra. Not only humans, but a wide variety of species such as beastmen, demi-humans, and mechanical lifeforms live together in the same galaxy. With the development of interplanetary routes and warp gates, space travel, studying abroad, migration, and trade have become a matter of course in daily life.

This universe is filled with "Astra," a fundamental energy said to have existed since before its birth. This power, dwelling in all life and stars, manifests diverse "Astra Abilities" such as fire, lightning, ice, gravity, and healing by resonating with the "Astra Core" possessed by a select few.

However, that power is not just hope. Astra stained by negative emotions transforms into "Dark Astra," harboring the danger of creating "Monsters" that attack people and "Villains," criminals who have gained immense power.

The Galactic Hero Association was established to protect the peace of the galaxy. Gifted individuals pass rigorous exams to obtain hero licenses, control Astra with specialized transformation devices, and fight clad in hero suits optimized for their own abilities. Heroes belong to characteristic hero agencies on each planet, continuing to take on challenges in rescue, maintaining public order, and resolving interplanetary incidents.

And at the center of Earth's largest city, "Diversity," tower the Galactic Hero Association headquarters and the super-massive facility, the "Parallel Tower." It is rumored that secrets capable of overturning even the history of the galaxy's birth lie dormant in that tower, but almost no one knows the truth.

Homeworlds, species, and beliefs may differ. Nevertheless, the desire to protect someone binds the heroes throughout the galaxy as one.
