As a result, Mibu Roshi-gumi became a group of about 36 men, and was assigned by Katamori MATSUDAIRA, Kyoto Shugoshoku, to control lawless acts by Sonno-joi extremists (loyalists aiming for overthrow of the shogunate), and guard in the city of Kyoto.
その結果36人余の集団となった壬生浪士組は、京都守護職・松平容保より、主に尊攘激派（勤王倒幕）浪士達による不逞行為の取り締まりと市中警護を任された。
