Sword Birth

Sword Birth, also known as the Creation of the Demonic Sword, is a Sacred Gear wielded by Yuuto Kiba.

Summary
Sword Birth is one of the two Sacred Gears that is used by Yuuto Kiba.

In Volume 3, Yuuto manages to gain his Balance Breaker, the Sword of Betrayer, after fusing together the souls of his friends who were victims of the Holy Sword Project and his Sacred Gear, Sword Birth.

Abilities
Sword Birth has the ability to create numerous Demon Swords of different attributes according to the will of the user. The swords, however, are not as powerful as one of the Excalibur fragments. When strengthened by the Boosted Gear Gift, Yuuto can create countless Demon Swords from the ground to attack the enemy.

After gaining the Sword of Betrayer, the Sword Birth can be use to create Holy Demonic Swords of different attributes. The Holy Demonic Swords are shown to be roughly as powerful as four of the Excalibur fragments combined.

In Volume 6, while Issei was in Juggernaut Drive, Yuuto was able to create a temporary shelter made of swords using Sword Birth.
