Mezamegan

The Mezamegan is a dojutsu utilized by the extinct Hiro Clan. Mezamegans, unlike other dojutsu, are vastly different in color and shape. The ability of the Mezamegan is not evident until it's full development. The effect of the Mezamegan is temporarily lethal to the user and can only be used once before the Mezamegan needs to redevelop. The ability of the Mezamegan is known as slight awakening and awakens a rare nature release. The only danger is the release of said nature release is the literal release of said element from the user's body. This can be healed, however. The Mezamegan in conjunction with blood release causes an infinite Mezamegan which does not need redevelopment.
