Murasame



One cut killer: Murasame is an offensive Teigu in the form of a long katana that Akame, a Night Raid member, uses.

This blade is sentient to some extent killing or injurging anyone who holds it that isn't it's user.

Abilities
It is a poisonous blade that can kill a person with only one cut. Once the sword pierces skin, it injects a lethal poison into the victim, killing them within seconds. However its ability only works on organic things that have a heart, rendering it ineffective against Armor and Biological Type Teigu, as well as machines.

Cleaning this weapon is very dangerous, as the slightest cut can kill the user.
