King of Assassins Incident
Together with Piano Man, Albatross, Lippmann, and Iceman, Doc surprised Chūya and congratulated him for his first-year anniversary in joining the Mafia. For their gift, they gave Chūya a photograph of him in his childhood, and Doc also gave him various files after claiming to have sifted through dental and other medical records. Afterwards, the Flags played billiards in their usual place, where an unknown man suddenly joined them.

The Flags engaged with the man named Adam, suspecting that he was an ability user and may infiltrate the Mafia facility, more so after learning that he was a detective. However, this misconception was soon relieved once Adam revealed that his mission was to protect Chūya and arrest an assassin named Paul Verlaine. The seven soon continued playing billiards, though Adam eventually picked Chūya up away from the pool hall, much to Doc's bewildered amazement.

During Chūya's absence, Doc and the other Flags were "summoned" by the boss, Ōgai Mori, but they were actually ambushed by Verlaine. Chūya returned soon after, where he found Doc amidst the other corpses. A dying Albatross had clutched Doc by his collar, unknown to him that Doc's body was separated from his lower body that couldn't be found.

A funeral was held for Doc and the other Flags the following day after their deaths. He would later appear in a trance-like vision to Chūya alongside the other Flags.
