Yatsufusa

The Teigu is shown to be a long Katana with two powers, both related to corpses.

Abilities
Yatsufusa is a blade-type Teigu that is able to control a maximum of eight corpses that it has killed. The user can also manipulate the skills and abilities the living corpses had in life.

The Teigu's second ability is that it has the power to control anything as long as it is dead. This power allows the user to summon any dead creature to his/her side.
