Klint van Zieks
"I will not here discourse the corruption rife among the aristocracy, which is to me, as one of them, so apparent.”

Klint van Zieks was an English prosecutor and the older brother of prosecutor Barok van Zieks.

Celebrated Prosecutor[]

Klint van Zieks was born into a respectable, thoroughbred British aristocratic family in the late 19th century. Despite his privileged upbringing, he was deeply committed to the principle of equal treatment under the law and quickly rose to prominence as a brilliant prosecutor. His dogged pursuit of corruption across all London’s populace led to his promotion to Director of Prosecutions, and his success inspired his younger brother Barok to follow in his footsteps. It was during this time he wed into the wealthy Baskerville family, who gifted him a lavish jewel-studded collar for his beloved hunting hound, Balmung. He also became close friends with Genshin Asogi, a detective and one of three Japanese students living in London as part of an exchange program.

The Hound of the Baskervilles

Ten years prior to the events of The Great Ace Attorney Chronicles, Klint’s passion for the law brought him to a breaking point. No matter how hard he worked to reform the legal system, powerful criminals among the aristocracy continued to escape accountability using the vast resources at their disposal. Van Zieks came to the conclusion that the only way to stop such monsters was to become a monster himself. He first murdered a corrupt member of Parliament’s House of Lords, in what became his modus operandi as the Professor: he set Balmung upon the man, whose throat was then ripped apart by the giant hound.

After the second Professor murder, fellow prosecutor Mael Stronghart quickly deduced van Zieks was the culprit. He blackmailed van Zieks into killing those whose deaths would benefit himself, threatening to reveal the truth to Klint’s wife and his younger brother should he refuse. Unable to bear the thought of his family discovering his deeds, van Zieks complied, even dispatching his beloved former mentor so Stronghart could further his own ambitions. The toll these deaths took on van Zieks was noticeable to his loved ones, though they did not know the true cause. He would commit three more highly-publicized murders as the Professor, before his killing spree was brought to an abrupt end.

Klint van Zieks
"There is no path back to the light. Be it I or my dear friend Asogi who dies this night…I am eternally damned. To my extortioner, Mael Stronghart…may you feel the jaws of the beast at your throat every time you swallow.”

Van Zieks pens his confession as Genshin Asogi looks on.

Late one night, six months into the Professor killings, van Zieks was confronted in his home by his investigative partner, Genshin Asogi, who had worked out on his own that Klint was behind the murders. Asogi proposed they duel to allow his longtime friend an honorable death, and van Zieks accepted on two conditions: that he be allowed to write a last will and testament confessing his crimes, and that Asogi would ensure protection for Klint’s pregnant wife. Asogi agreed to his terms, and van Zieks personally confessed to his wife before penning his will. The duel ended in van Zieks’s death from a stab wound to his heart. Asogi was later witnessed by household staff fleeing the estate, leading to his arrest. Seizing the opportunity to prevent a potential scandal, Mael Stronghart pinned the Professor killings on Genshin Asogi, who was convicted for them in a closed trial. Van Zieks was publicly named as the Professor’s fifth and final victim, and his autopsy was altered to ensure Asogi’s guilt in the eyes of the judiciary.

In the days before his execution, Asogi gave Yujin Mikotoba instructions to find Klint's wife, who was about to give birth at a dilapidated house. Though Mikotoba helped successfully deliver the baby girl, the woman died shortly after. Before his ordered return to Japan, Mikotoba left Klint's baby in the care of his English detective partner, Herlock Sholmes.

Klint van Zieks’s death deeply affected his younger brother Barok, who had spent his entire life in admiration of Klint and continued to view him as aspirational after his death, ignorant of the truth. His late brother’s prosecutor’s badge is present on his jacket lapel at all times, and a large portrait of Klint in hunting attire decorates his office. Klint himself appeared to care about Barok very much, asking for his brother’s forgiveness at the end of his written confession.

End of spoilers.



Klint Van Zieks was once a brilliant and respectful prosecutor and very well known in the Prosecutor's Office. He aimed at ending the non-stop corruption and crime that was plaguing London's streets, and valued equal treatment of all under the law. His younger brother Barok looked up to him in honor, and viewed him as a "guiding light".

However, as time went on, Klint's passion for the law began to change him. No matter how much he did to reform the Legal System, crime continued to spread rampant in the United Kingdom, and many criminals managed to escape pursuit using any means necessary. Klint began to believe that in order to truly prevent these monsters from plaguing England any further, he must become a "monster" himself. And so, he became a serial killer, targeting London's high ranking aristocrats who were secretly criminals themselves. When Stronghart blackmailed him into continuing his killing spree, Klint couldn't face the thought of his actions being revealed to his family, especially his wife and brother.

It wasn't until he killed his own mentor, the former Lord Chief Justice, where Klint realized how much the darkness exhibited by London's criminal underworld consumed him. As a result, when Genshin Asogi challenged him to a duel after learning of his heinous actions, Klint didn't hesitate to agree, and so, he wrote a will, telling how he deeply regretted his actions and knew he was damned.


  • Klimt possibly derives from artist, Gustav Klimt, as Barok's name is homonymous with the Baroque style of art. Gustave Klimt was an Austrian symbolist painter and one of the most prominent members of the Vienna Secession movement.
    • His English name Klint likely has the same origins, with the change from "m" to "n" possibly being made to make the name easier to say, or sound more legitimate as a given name.
  • His surname van Zieks may reference the Japanese phrase '万事休す' (ばんじきゅう), meaning "there is nothing more that can be done; it's all over". van Zieks by itself can also be translated to "of the sick" in Dutch, possibly if unintentionally referencing the Grim Reaper's emergence as a psychopomp during the Black Plague.
