Abilities and Powers
Tachi Namida is a sword that seems to be able to cut nothing yet also something at the same time all depending on how one weilds it. At the same time it senses to see if one is good or evil. If a evil person tries to use it, they end up having their soul ripped out of their body and their body destroyed (much like a person without their shadow) However if a person that is good uses the sword, No harm will come to them unless they turn evil.
