Sounds pretty much 1-for-1 with Katou's legend. If memory serves, it was actually a Calabash Flower that he grew and cut, to decapitate the onlooker that exposed the secret to his disappearing bull act. It was also the act that put him on Uesugi Kenshin's radar (and eventual downfall).

If there needs to be an activation requirment, aggro would make sense, as he used it in retribution for having his secrets exposed.
