Issei eventually manages to make a temporary alliance with the Church duo, where they will help the two of them to retrieve the Excaliburs in return for allowing Yuuto to destroy the Excalibur and letting go of his past. This allowed Yuuto to learn of the person in charge of the Holy Sword Project, Valper Galilei. The team was eventually attacked by Freed Sellzen and Valper which causes Yuuto to chase after them.

During the meeting, Yuuto also gave a Holy Demonic Sword to the Archangel Michael in exchange for them ending their Holy Sword research.

In Volume 5, Yuuto, like the rest of Rias' peerage, returned to the Underworld for the Young Devils Gathering. In the Underworld, Yuuto trained in maintaining and using his Balance Breaker for long fights. During the Rating Game between his master Rias and Sona Sitri, he and Xenovia faced off against Tsubaki Shinra, Meguri, and Yura, defeating Meguri and Yura after Xenovia lends him the Durandal which he fuses with his Sword Birth to create the Durandal Birth, forming numerous Durandal blades to pierce the two of them.

The Heroic Oppai Dragon
In Volume 9, during his trip to Kyoto with second year students of the Occult Research Club, the team cross path with Khaos Brigade's Hero Faction. Yuuto and Xenovia fought against Siegfried and was defeated easily by Siegfried.

In Volume 10, after being defeated by Siegfried, Yuuto trained to achieved the Balance Breaker of Blade Blacksmith which he reveals in his fight against Beruka Furcas during Rias and Sairaorg Bael's Rating Game. Yuuto, Rossweisse, and Xenovia then faces Sairaorg in a three-on-one battle but lost to the latter (although they managed to cut one of Sairaorg's arms).

In Volume 11, Yuuto receives a promotion recommendation along with Akeno and Issei. While the group was resting after the test, they are ambushed by Cao Cao and Georg who came to steal Ophis' powers. The battle ended with the Gremory and Vali Team losing to Cao Cao and Ophis' powers being stolen. Both teams were then attacked by a region of Grim Reapers and Siegfried. He then has his rematch with Siegfried which ended with Yuuto cutting off one of Siegfried's Dragon Arms. Like the other members of the Gremory Team, Yuuto was shocked to learned that Issei "died" at the end of Volume 11.

At the beginning of Volume 12, Yuuto and the other members of the Gremory Team stayed in the Gremory Palace after the whole team was still at shock with Issei's death especially Rias and Akeno. Yuuto later goes to the basement of the Gremory Palace to check on the Vali Team while asking the original Sun Wukong about Samael's curse. The Gremory Team later goes to the Human world to ask the creator of the Evil Pieces, Ajuka Beelzebub, to check on Issei's Evil Pieces and was surprised to see the Old Satan Faction and Siegfried who came to offer an alliance with Ajuka. He then faces off against Siegfried in their third and final encounter. During the fight, Siegfried injected the blood of the Original Satan which made his body undergo a demonification process where he transformed into a monstrous spider and fused with his Demon Swords and Sacred Gear. With this new form, Siegfried easily overwhelms all the members of the Gremory Team, cutting off Yuuto's left arm (which he was able to reconnect later in the battle through the combined efforts of Ravel and Asia) and injuring both of his legs. The battle was overturned when one of Issei's Evil Pieces transformed into the Ascalon, allowing Yuuto to injure Siegfried. Siegfried finally lost to the latter after his strongest Demon Sword, Gram, left him and chose Yuuto as its new wielder. As he received attacks from the Gremory Team with Yuuto dealing the final blow by stabbing him with both Gram and Ascalon, his body starts to crumble away. After the battle, Siegfried's Demon Swords leave him and choose Yuuto as their new wielder. At the end of the same volume, Yuuto is also officially promoted into a Middle-Class Devil.

The Legend of Oppai Dragon and his Lively Companions
In Volume 14, Yuuto is shown to be training Xenovia on how to better use her Ex-Durandal, claiming that should Xenovia master all seven abilities of the Excalibur in addition to the Durandal, she would surpass him as a swordswoman. He later goes to Romania along with Rias and Azazel in order to find out more about Gasper's unknown power.

Powers & Abilities
As a Knight, Kiba possesses superhuman speed and is heavily skilled in swordsmanship, what Issei has called God-Speed. He has only been seen using 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 it 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.
