Sabiiro no Armor  

Rusted Armors, 錆色のアーマ, Rusted Armors: Dawn

During this tumultuous period in Hinomoto, known as the Warring States era, there exists an uncharted territory called Kinokuni. Nestled deep within the dense forest of this region lies a group that uses "Yatagarasu" as their flag and wields guns as their weapons. This group is referred to as Saikashu. Magoichi, who hails from a foreign land and has assumed leadership of Saikashu, arrived in Hinomoto. Meanwhile, Saburo, a native of Hinomoto, quickly recognizes the threat posed by European powers and works tirelessly to safeguard his homeland. The destinies of these two individuals, who were initially destined to never cross paths, will be intertwined as they engage in battle against invaders from abroad.
