The Two-Tailed Monster Cat (ニ尾の化け猫, Nibi no Bakeneko) is a blue-flamed, odd-eyed bakeneko. It was sealed within Yugito Nii of Kumogakure when she was two years old. It has been captured by Hidan and Kakuzu, then extracted and sealed by Akatsuki.
According to Madara Uchiha, the Two-Tails came into being near the end of the waning days of the Sage of the Six Paths' life; to prevent its resurgence, the Sage split up the demon's chakra of the Ten-Tailed Beast into nine separate, monstrous constructs of living chakra, which would become known as the tailed beasts. Like the One-Tailed Shukaku, many people believed that the Two-Tails was once a human that turned into a living ghost (生霊, ikiryō). The Two-Tails eventually fell into the possession of Kumogakure and sealed into a two-years-old Yugito Nii. She was placed into a detestable training program in order to learn to control the Two-Tails' power.
Activity inside Yugito Yugito and the Two-Tails.As the Two-Tails' jinchūriki, Yugito had the ability to transform into the monster cat, giving her access to its strength and its ability to breathe fireballs from its mouth without losing much control.
Hidan and Kakuzu arcEdit
Soon after her introduction, Yugito was captured by two Akatsuki members, Hidan and Kakuzu, although it is unknown who was specifically assigned to capture her. Despite luring her two pursuers into a closed space, sealing the exits, and transforming herself into the Two-Tails, Yugito was overpowered and rendered unconscious by the two Akatsuki members. Zetsu later arrived to take her off their hands, and she later died as a result of having the tailed beast extracted from her.
Cats are the common species throughout the world, and stories of bakeneko (化け猫, monster cats) are popular throughout Japan. In myth, when a cat reaches a certain age, it grows larger, and its tail becomes longer and forks in two, and is then called a nekomata (猫俣, forked-cat). Reportedly large in size, these cats are said to have the ability to manipulate the dead like puppets, and have been associated with strange fires and occurrences. This may be related to the monster cat's nickname and its fire-breathing abilities.
