Korutski- The Streaming Chakra Blade
Story time(topkek) - The Korutski Blade forged by the elders of the Hidden Haze which was given an unique Sealing ability, was once used for keeping peace between the neighbouring villages, located not far from the Hidden Haze. There it was kept in a shrine of it's own glory until... Five rogue Shinobi, of god-like strength attacked the village. Being on par with the Haze's Kage, he had no choice but to use the blade in battle, and surprisingly managed to seal all 5 Rogue Shinobi, but the blade also comes with a heavy price... Those who use it to seal, must also be sealed, hence giving birth to the blade known as the, Korutski - The Streaming Chakra Blade.
Effect/Compatibility - The user has to pour a significant amount of Chakra into the blade to make it grow 10 fold, and the wielder must be highly experienced in Kenjutsu to wield such a blade, after it has grown -- No Chakra nature needed.
