Shin Kazusa

Shin Kazusa serves as the young yet resolute prince of Tourai, a nation struggling to survive in a desolate world ravaged by the toxic substance known as 'Shinobi.' Bearing the immense burden of protecting his people, he initially refused to rely on the legendary weapon 'Kishin Sho,' firmly believing that humanity must forge its own strength rather than depend on mythical power. Though outwardly stoic and unyielding in his convictions, witnessing the unwavering determination of protagonists Amane and Su'on ultimately moved him to extend crucial support, cementing his role as an indispensable ally to the main party.
