Chess Shinigami

Zanpakutō is a manifestation of its owner's soul (avatars), and has a unique name (Member name) which is required for a shinigami group to learn in order to use Shikai and Bankai. As such each Zanpakutō has unique abilities that match their owner's characteristics and personality, and their names usually hint to what these powers may be. A Zanpakutō spirit is part of its owner's soul and often share the same personality traits. At the same time, they are also independent, and thus can be considered a Shinigami's partner in battle. Because they are part of their owner's soul, a Zanpakutō cannot be replaced, though it will slowly regenerate if broken.
