Chikiri

Chikiri is a sword forged by Chinami's mother but the former stole when she ran to Konoha.

Creation
Chinami's mother had already given birth to her daughter. Telling the young'un to stay where she was, Mom left for. Just in case, she left a clone of herself to watch over her daughter. Mom and her lover decided to forge a sword that she wanted to give to her daughter as a present. To make the sword more powerful, Mom soaked the vat with her blood, nearly draining herself dry. The completed sword was an oddity. She sheathed the blade and used it as a cane, when walking home. Chinami was only a few months old but the girl knew that she wanted the blade for herself. At the age of 5, the young Chinoike slayed her mother with the sword and with tears in her eyes, ran in the direction of Konoha (although she had no idea where it is).

Appearance
The blade is a deep red except for the spine of the blade: blazing white. The blade itself is decorated in the same way as the Seisekken I, even though they had no knowledge about that blade.

Stability and Personality
Chikiri is a very stable blade able to cross with not one but two of Ryo's Golden Wheel Reincarnation Explosions as seen during the Chūnin Exams. Chikiri is also quite very alive. When Chinami first stole the blade, she remembered a voice in her head, scolding her for stealing the blade. By the tone of the voice, Chinami determined it to be female.

Cutting Power
Chikiri can easily slice through trees with no effort. It can cut through chakra but not concentrated chakra. The blade doesn't seem to like star chakra as when Chinami uses Stellar Sage Mode with Chikiri, the blade has a tendency to cut through Chinami's chakra shroud, much to Chinami's irritation.

Regeneration
If nicked, the blade regenerates itself by absorbing iron from blood or any liquid that contains iron that is on the blade. This ability is similar to 's ability. One probable reason that Chikiri obtained this ability is that when forged, blood was introduced into the vat.
