Each code name is derived from a different species of bird. NPSF squads labeled with a lower number are judged to have better abilities, with single-digit squads being especially elite. Squad No. 1 is formed on an as-needed basis from other squads and has no permanent members. A ninja usually has a Kekkai, which is hereditary ability that grants them superhuman powers. Regardless of lineage, a user must awaken their kekkai to use it.
