After Bolic's assassination by Night Raid, Honest couldn't believe that his plans of subduing the Path of Peace would be thwarted despite the Jaegers' protection, even by Esdeath. After Tatsumi's capture and Lubbock's death in an attempt to infiltrate the royal palace, Honest was informed by Budo of his son Syura's death. He at first cried mourning but then quickly brushed it off, scheming to have another one who will not fail him much to Budo's disgust for his lack of sympathy of his kin.
Later at the day of Tatsumi's execution meant to demoralize the Revolutionary Army, Honest hears The Emperor's impressive speech to the people before leaving, prompting Budo to be suspicious about his motives long after Night Raid arrived to rescue Tatsumi.
In the outbreak of the mass revolt by the capital's population and the siege of the Revolutionary Army, Honest convinces the child Emperor that it's time to show the people why they should fear the ruler of the Empire as he shows him the "legendary" Teigu, the Shikoutazer.
In the ongoing siege on the capital, Honest was with the Emperor and the Imperial Guard of the late Great General Budo when the few remaining members of Night Raid infiltrated the royal palace successfully to kill him once and for all. Honest finally compels the child ruler to activate the Shikoutazer and lay waste on the capital all in the name of protecting the Empire, earning Tatsumi's anger.
Witnessing the all-out destructive battle between the Emperor and Tatsumi clad in his Incursio, Honest keeps cheering for the boy, telling that he made his parents proud "protecting" the Empire after their mysterious murder (it's suspected that he had in hand of this), but was later shocked when Wave clad in his Grand Chariot, who finally saw the error in the Empire's ways, joined the fray and saved Tatsumi from a fatal blow.
Seeing one of the Jaegers fighting against the Emperor, Honest accuses Wave of defecting to the Revolutionary Army but was rebuffed by the latter who declared that he fights for the people even against the Prime Minister much to his shock but later recomposes himself under the belief that the armored Teigu users will be no match for Shikoutazer.
However, when Tatsumi in an evolved Incursio destroys the Emperor's Teigu for targeting the weak spot, the prime minister was extremely shocked and attempts to flee as he aims to scheme his way to power again someday but was intercepted by Leone. Attempting to defend himself, Honest uses his Erastone to destroy her Lionelle and then fatally shoots her in the stomach several times, but failed as Leone killed him by crushing his skull several times.
