Rusted Armors

Tsurukubi and Hotarubi leave the Saika village. Magoichi and Deku set out to find them. During a break, Magoichi explains to his comrade how Tsuru and Hotaru met.

Hotarubi recalls his memories, the assassin training he received as a child, his meeting, then his escape with Turukubi. He also remembers what Tsurukubi told him about Armors, which tap into the life energy of their wearer to unleash their power.

Cornered by the Spanish conquerors, Kurohyo sees his life flash before his eyes: his past full of material and physical difficulties, in addition to suffering cause by the absence of his father, whom he blames for the death of his entire family.

The commander of the conquistadors reveals Magoichi's mysterious past, and Saburo returns to put the Saika through rigorous training.

Time is running out, and if the Saika cannot complete Saburo's training, they may not live to fight the conquerors.

Saburo remembers his past with Hototogisu and another person who marked his life, and who made him decide to forge his own path in the future.

Lucio has appeared and has already become a major threat to Magoichi and his friends. But he and the people of Saika seem to have another unexpected enemy.

Saburo warns Magoichi, who must choose between sealing his friends' fate or his brother's, but the decision is too difficult. Perhaps there is still another way out?

Ageha acts unexpectedly, but her past can explain a lot. Even so, uncertainty haunts his days. Because of the upcoming fight against Lucio, there is no longer room for uncertainty...

Magoichi is determined to have his brother back by his side, but Lucio seems equally determined to fulfill his ambitions of spreading death wherever he goes.
