Zanpakuto

A Zanpakuto is a powerful, personalized weapon wielded by Soul Reapers in the anime "Bleach." Each Zanpakuto is an extension of its wielder's soul and has its own unique name, abilities, and personality. They typically take the form of a sword and can transform or unlock special powers through a process called "Shikai" and "Bankai," significantly enhancing their strength. The Zanpakuto reflects the character’s spirit and mastery over their spiritual energy, making it a vital tool in their duties of protecting the balance between humans and spirits.
