Dragon Blade (Kasumi12346)

The Dragon Blade is an ancient sword created by the Ryū Clan as a way to kill Ryuuki. It is a sword of tremendous power that requires and enormous amount of chakra to use. So much in fact that only those chosen by fate like Naruto and Otohime can wield it.

Description
The Dragon Blade is made from the scales of the Ryū Clan ancestor. Perfectly forged together to give the sword an unbelievably sharp blade, able to cut through diamonds and chakra like a hot knife through butter. Just like the dragon the scales came from, the sword has the ability to drain the chakra from whatever it touches. Regardless of whether it is its wielder, the person it is striking, tailed beasts, or techniques. Once absorbed a portion of it is used to strengthen the sword. The wielder can turn the rest of the chakra the sword uses into a powerful type of energy called draconic energy by circulating the chakra through the blade. Once created the the energy can be released from the sword as a blast, shockwave, blade, or anything similar. If one of its jewels, known as Chakra Nature Jewels, has been placed in the hilt the wielder can flow it into the jewel to give the user to release the jewel's respective chakra nature from the sword in various ways.

When the sword is in close proximity to Ryuuki it will absorb even more chakra from its wielder because of how the sword was forged. The sword doesn't use the chakra to create draconic energy or a chakra nature, but to augment its absorbing properties. This happens so that it can extract the tailed beast DNA Ryuuki has, giving it the ability to strike Ryuuki with a fatal blow. The DNA is then used to turn someone else into a tailed beast. Someone more deserving of its power: the wielder.
