Hmm.. Been a while since last I thought of Bleach lol ... xD

Name: Viper Obsidia
Release word: Ssssssssss ... I mean "Bare your fangs!"

Shikai description: Naginata with a pitch black blade

Bankai: The blade of the naginata extends inward .. It's like the handle of the naginata will unsheathe to be a blade.. Well it is that. It extends until it becomes a sword. The sword grants speed. The black blade is also imbued with super-concentrated energy from the user , which helps it cut stuff.
The real strength of this is , once it strikes a mortal being , the being's movements become slower , and maybe some poison effects xD .

Bankai release: Ssssssss! (Go shed your skin, Obsidia!)

Weakness: If the handle is broken, it dies... So basically don't let me hit ban kai lol. xD
