Yatsufusa

March of the Dead: Yatsufusa was a Teigu in the form of a long katana with the power to reanimate and control corpses. It was the second Teigu owned by Sidero and was destroyed by Wave.

Abilities
Yatsufusa was a blade-type Teigu that is able to control a maximum of eight corpses of those whom it has killed. The user could also manipulate the skills and abilities the reanimated corpses had in life. The puppets were known to retain their habits, desires and traces of personality that they had in life, sometimes enabling the user to utilize these to their advantage. However, it could backfire as well, ss Sidero noted that the puppet's condition remained the same as it was upon death, meaning that the puppets could not learn new things nor improve their physical capabilities beyond those achieved before becoming a puppet.

For each puppet the user actively controls, they became weaker. If a puppet was destroyed, it caused the user to release control and the user regains some power.

Puppets

 * Run: A former fellow comrade to Sidero. He still wields his Teigu, but his wings have turned black.
 * Green: Green is in love with her, but she doesn't return his feelings and instead she valued him as a friend and comrade. His neck is turned as it was when he died.
 * Wall: A former famous guardsman. He had a shield with a hidden lance in it that could be fired. He was destroyed by Bols' Teigu's self-destruction.
 * Doya: A former assassin from the Northern Tribes that dual-wields pistols. Her arms got cut off by Enshin and eventually, she had replacements grafted on from another corpse but it caused her to be unable to use her original power.
 * Henter: A former survivor of the Ban Tribe. He had tricky movements and a knife, but was destroyed by Chelsea, who tricked him into believing that she was also a survivor before assassinating him. Unlike the others, he seemed to be able to talk.
 * Various Unnamed Puppets: A small group of weak puppets summoned as a distraction.

Trivia

 * Yatsufusa (八房) can be translated to English as "Eight Tassel". Tassel is French for clasp, meaning to grip tightly or attach/fasten. Sidero is able to "fasten" the souls of her victims to Yatsufusa but can only actively control eight, hence the name.
