Megundal's trial

During the trial, he was the second juror to vote Cosney Megundal guilty. He tried to justify his position to defense attorney Ryūnosuke Naruhodō by stating that the manner in which the victim was stabbed did not matter, which Naruhodō disproved by presenting the autopsy report. Despite this, he did not change his vote until Megundal told the court that he released Gina Lestrade, only to change back to guilty when it was assumed that she was lying. After the trial's conclusion, he commented the entire case was too much to ask of a jury.

Eight month later, the banker tried to steal the arm of the John Clay figure in Madam Connette Rozaic's wax museum, but she caught him in the act and knocked him unconscious with the arm.

Personality
Juror 1 came across as a rather serious and no-nonsense gentleman, but could be rather overenthusiastic at times.
