Yakusoku -Promise code- Lyrics - Qualidea Code belongs to the anime Qualidea Code, take a look at the argument:

During an idyllic and serene day, the heavens rupture, unleashing the enigmatic entities known as the Unknown, who mercilessly launch a swift and savage assault on humanity. To safeguard the nation's future, Japan takes a drastic measure by cryogenically preserving its children, shielding them from the harrowing dangers of war. After the passage of numerous years, humanity establishes a stronghold on a fragment of Japanese territory, which now stands as the last bastion in the ongoing battle. As the threat of extinction diminishes, the children reawaken from their icy slumber, only to discover that their time in cryogenesis has gifted them with extraordinary abilities called Worlds, each unique to its bearer. Entrusting the six most formidable individuals with leadership roles, the reclaimed cities are placed under their command, as they harness their powers to defend against relentless invasions. Childhood friends Ichiya Suzaku and Canaria Utara take charge of Tokyo, siblings Kasumi and Asuha Chigusa govern Chiba, while Maihime Tenkawa and Hotaru Rindou oversee Kanagawa. However, as time passes, the once united front grapples with internal conflicts, stemming from clashes of personalities and the weight of responsibilities. Petty rivalries sprout amidst the routine Unknown assaults, leading to incessant quarrels among the city heads and subheads. With an unexpected escalation in the intensity of attacks from the Unknown, the leaders of the three cities find themselves at a crossroads, where cooperation becomes paramount to ensure the survival of humanity's last line of defense against annihilation.
