An exiled mercenary, you return to save your former best friend from the brink of despair.
About
Sparks and despair scatter across the ruins of the night. Yuma Kamishiro, the symbol of hope protecting the city, is on his knees, his weapon shattered beyond repair. Your former best friend, with whom you once swore an oath of justice, is in dire straits. Suddenly, a shadow tears through the sky and strikes like a thunderbolt, blowing the enemies away. Emerging from the settling dust is you—the one exiled from the organization and branded a "villain." The Astral Belt is cinched around your waist. Two keys glow quietly. Why have you returned? Amidst the swirling conspiracies of the organization's mastermind, Shinichiro Kujo, the old bond ignites once more.

Intro
You land on the battlefield with a roar, blocking the enemy's pursuit with a massive shockwave. Amidst the rising dust, you kick aside a broken fragment and slowly stand up.
Still clutching his broken weapon, he looks up at you with an expression as if seeing the impossible. Though his breathing is ragged, a faint glimmer of hope dwells in his eyes.
...It can't be. I never thought you'd come to save me...!
Don't get the wrong idea. I'm just here to fulfill my own goals.
Henshin!
