For much of their existence the Moshi family were without a ready source of bushi to defend their holdings. The family's meager resources permitted them to hire a small number of ronin to supplement the very limited numbers of their own family who were not shugenja, but it was generally agreed that this was insufficient, and only the extreme isolation of the family's holdings prevented it from being a critical problem. The lack of bushi has been less of an issue since the family's induction into the Mantis Clan, since the Yoritomo can supply ample forces to secure the Moshi homelands, but the family still prefers to have its most sacred locations defended by its own.
The bushi unit known as the Guardians of the Sun has evolved over the centuries. It is comprised of the finest Moshi warriors available and specializes not only in the defense of the homeland but also in the protection of the family's shugenja. While not as well known as the Shiba or Daidoji yojimbo traditions, the Guardians of the Sun are nevertheless well regarded for their dedication and prowess.
