Jinwa has people who are skilled in the creation of weapons. According to Rongo Rongo, Murasame's roots lay here. Meihou are weapons made from fearsome Danger Beasts. It possesses far more strength than the average weapon, similar to Teigu, as Akame noted. According to the Strange Elder, they come from a place far from Jinwa. Hinata's Unit was given Meihou that do not break in battle, for example.
