Rappa'shu Clan

The Rappa'shu Clan (喇叭手一族, Rappa'shu ichizoku) is a powerful clan of ninja that currently dominate Getsugakure in terms of prestige and influence. They are large, though not so large as the Jiyūkari Clan, but have a much more solid culture, with a very rigid system of ninja training putting them at nearly the same level of shinobi as the Jiyūkari, and with their ninja considered the most solid, and in many cases exceptionally powerful.

The Rappa'shu Clan use their hiden jutsu, the Viper Fang-Wyvern Horn Technique, which focuses on various forms of paralysis upon the opponent via tapping different areas of their body and sending out a flow of chakra to paralyze them, and then expounding on it via different "orders" given to the chakra-controlled neurons in the opponent's body via different signals blown from a special horn, which each clan member must create from the horns of various animals in the mountain passes near Getsugakure. The greater the horn, the more prestige it grants the holder and his branch of the clan.
