Powers & Abilities
Being a "Knight"-type Evil Piece, Kiba possess superhuman speed and is heavily skilled in swordsmanship, what Issei has called God-Speed. He has only been seen to use one sword at a time so far, but is depicted with two on his character sheet.

Kiba's primary weapon is the Sacred Gear "Sword Birth", which has the ability to create an infinite number of Demon Swords at his disposal, such as the Holy Eraser and Flame Delete. He later obtains a sub-species Balance Breaker called "Sword of Betrayer", which is a fusion of a Demonic and a Holy Sword. He received it during the fight with Freed after he "merged" his Sacred Gear with the spirit of his comrades.

Kiba later gains a second Sacred Gear, Blade Blacksmith, in Volume 3 (it was not revealed until Volume 10) and a sub-species Balance Breaker, “Glory Drag Trooper”, which creates an army of Dragon Knights which he uses to fight Beruka Furcas. Yuuto, however, cannot use both Balance Breaker's at the same time so he can only choose to use either the Sword of Betrayer or Glory Drag Trooper.

In Volume 12, Yuuto gains Gram, one of Siegfried's Demon Swords, after Gram left Siegfried and chooses him as its new wielder. The remaining swords chose Yuuto as their new wielder following Siegfried's death.

Yuuto has all the powers and abilities common to Devils, including the power to cast spells. He has also shown some ability in crafting illusions, using one to draw Siegfried's attention during a battle to allow him to perform a sneak attack.
