During the event, Kubota represented the cast in reading out a letter addressed to Karasawa where they pledged to keep the spirit of "Last Cop" forever and pledged to follow the latter's lead going forward. In response, Karasawa said that he also had a surprise for Kubota by giving him a jacket similar to the one worn by Karasawa's character Kyogoku. However, the jacket was obviously too small for Kubota which led Karasawa to joke that he should not give it to Kubota after all even though he had bought it specially for the occasion. This led Kubota to say that the jacket will stretch after some time so there was no issue even if it was too small for now.
