Gekkou no Kumoyoru

Gekkou no Kumoyoru, literally meaning Cloudy Night Moonbeam, is one of the jutsu the founder of the Ikari clan was said to possess, using with his Necklace of Infernal Harmony. It takes the form of a silvery-blue spear of chakra, hovering over the user's hand at its center, with a casing of cloud-like free chakra around the middle. It can be thrown at the opponent or stabbed, causing great damage.
