I think are good friend Kojirō shinomiya was whistle blower who told senzaemon on what azami was doing to erina his daughter and was part of the crew who took him down
Chapter 230 reveals he admit he likes Azami's Ideal on True Gourmet part, but somehow feels mixed up/whim and don't want to be involved with any feuds between Azami Admin & opposing food industries. Yet finds the Ideals happen to be too extreme/gone too far.
Ladies and Gentlemen, we got Shokugeki version of Jason Todd. Check his ending in Injustice 2, similar role about agreeing with dictator side, but don't really want anything to do with the feuds, & yet cannot let the side gone too far for their dictatorship methods.
