Seisekken I

A cursed sword forged and wielded by Hikari.

Creation
On break from her first mission, Hikari went on an expedition to search for metal to forge a sword. Once satisfied with the amount she gathered, Hikari began the forging process, imbuing chakra into every step. However, Hikari unknowingly cursed the blade during the process. Upon finishing, she gave the blade to her father to evaluate and test out. As if the curse knew, Seishi wasn't cursed.He congratulated his daughter on making such a deadly weapon. Hikari blushed, "Aw, Dad, don't embarrass me." Then, Hikari showed it to her team members. Again, as if the curse knew who's who, they weren't cursed. They congratulated her to which Hikari flushed. She then went to test out the blade herself. Upon slicing up some trees, Hikari finally realized that the blade was cursed.

Abilities
The blade's curse is its extreme sensitivity to chakra. If not a chakra that it itself recognizes, it will absorb the chakra. Essentially, if the sword ended up in the wrong hands, whoever was using the sword will have their chakra painfully drained. However, the blade did not curse Seishi or Hikari's team members when they wielded it. This proves that the blade will not affect those who are close to its wielder. Channeling chakra into the blade is relatively easy. Even Naruto, who sucked at chakra control, was able to channel his wind nature chakra into the blade. Due to this, Hikari's primary weapon is the Seisekken.

Appearance
The Seisekken is black with a distinct red hamon and its tsuba hand-guard has flower-like edges. Its red hamon (hardening line) is Kanemoto style, having the appearance of a saw or sharp teeth. It has no accessories on the hilt, being wrapped with black silk. Kashira, tsuba and kojiri end cap are golden, and the sheath is black, decorated with dark red circles split in even thirds.
