Yoroi-Shinden Samurai Troopers

he seal on the Yōja Realm breaks, and waves of Yōja soldiers begin invading the human world. With ordinary forces unable to stop them, five young warriors answer the crisis, samurai who can fight in special armor and push back the invasion. As the attacks escalate, the team is pulled into a new battle that spreads beyond single skirmishes, with human authorities trying to contain the threat while powerful figures from the Yōja side move in the open. The war forces the five to act as a unit fast, because every breach gives the enemy another foothold in their world.
