Musashi Hōjō, also known as Suiren no Musashi, is a fourteen-year-old boy and one of the five main protagonists in the anime Yoroi-Shinden Samurai Troopers. He was raised in the orphanage called the Forest of Truth, and his innate abilities as a Samurai Trooper were recognized, leading him to become the wielder of the Suiren no Yoroi, the Cyan Armor of Waterfall. He serves as a member of the DST, the government organization established to counter the threat of the Evil Clan.

Good-natured and approachable, Musashi has a notable daily habit of checking fortune-telling predictions on his smartphone and placing strong belief in lucky items and the advice he receives from such readings. This tendency reflects a superstitious but optimistic side to his personality. He bears the virtue of Shin, which represents trust, and this value guides his actions as a warrior and as a person.

Musashi shares a close bond with his older brother, Yamato Hōjō, also a Samurai Trooper. Both were raised together in the same orphanage, and the brotherly relationship is a key part of his personal motivations. Within the team of five new-generation troopers, Musashi’s role is that of a dependable and sincere fighter who relies on his armor’s water-based abilities in battle. The Suiren armor grants him powers associated with water and waterfalls, and he uses these to confront the forces of the Evil Clan.

Although details of his full character development across the series are limited to the first season aired in early 2026, his background as an orphan, his trusting nature, and his reliance on fortune-telling set him apart as a unique individual among the troopers. His journey involves growing into his responsibilities as a protector while maintaining the innocent and earnest outlook that defines him.
