After his departure, "Kato Kouban" became an honorary title in the group, with every vocalist joining afterward being the next generation Kato Kouban. Upon the announcement of Kato's withdrawal, their manager Watanabe Junnosuke temporary took over as the vocalist, declaring that he was the original Kato Kouban and that the Kato active prior to him was actually the "second-generation Kato Kouban".
On September 7th, an unknown vocalist took over the position as the "third-generation Kato Kouban" until their disbandment.
