Miyamoto Iori
As the adopted son and disciple of Miyamoto Musashi, the originator of Niten Ichiryu, Iori had trained with the sword from infancy. But the world had moved on from its war-torn era to a time of peace - a time without the need for swords. Moreover, his teacher had passed away before imparting the school's deepest mysteries.
 * The Gentle Swordsman

Unable to name himself the true successor of Niten Ichiryu, Iori decided not to seek out employment under a lord. He instead eventually made his way to Edo, where he spent his days in assiduous study of swordsmanship.

Ogasawara Kaya
Miyamoto Iori's younger foster sister. After Miyamoto Musashi's death, she was adopted by the Ogasawara family. Worried about her brother, she often stays at his house in Asakusa to look after him.
 * A Dutiful Sister

Edo
Rivaling Kyoto and Osaka in size, this metropolis is known for having numerous neighborhoods nestled within it. Though Edo was once a large patch of wild wetlands with few inhabitants, the area began undergoing gradual development after Ota Doukan constructed the Edo Castle there. After emerging victorious from the decisive battle of Sekigahara, Tokugawa Ieyasu chose to establish the shogunate in Edo, turning it into the center of Japan's new government.
