Vigilants were Shinjo Bushi who swore vengeance to the Kolat on the day of their gempukku and immediately thereafter set out to hum conspiracy agents. The school was formed after the Kami Shinjo purged the Unicorn Clan from the kolat and exposed the Unicorn Clan Champion Shinjo Yokatsu as a Kolat Master. The Shinjo Daimyo publicly denied that any of their family would act outside the law to hunt the Kolat.
