Tsuneyoshi is an old man, with long white hair, and beard.
Because of his seriousness and strong insight, the air around him is always heavy. He is shown as disliking nonsese as it shown he put his interest in the outcome rather than rhetoric excuse.
Raid of Kanou's LabEditar
Tsuneyoshi summoned Itsuki Marude to hear the actual conditions of Aogiri Tree but then asked him to leave since there was no news. He also asked him to hurry fearing the increase of victims' numbers. He was also mentioned to have appointed Kishou Arima and Juuzou Suzuya as ghoul investigators, recognizing their potential.
Post-20th Ward One-Eyed Owl BattleEditar
As his son and Kishou Arima appears before him, they discuss of the results from the operation in the 20th ward. Tsuneyoshi is seen holding a piece of paper with Kaneki's profile crossed out and marked as 'Erased'. He speaks to Arima informing him the 'ownership rights' are his and asks him what he will do about the name. Arima replies that he will entrust it to him.
