Previous studies have confirmed the effectiveness of using agents for a single day. However user may become bored with the agents’ manzai-style joke responses, and their motivation to continue the conversation may decrease. In this paper, we newly introduced simple and nori tsukkomi to tsukkomi agent and conducted a one-week experiment. The results of the one-week experiment using the prototype system showed that the users found the interaction humorous, and their moti-vation to continue the conversation increased when the agents made humorous statements during conversations with the user. In addition, we confirmed that users’ familiarity with the boke agent was improved by conversing with agents for multiple days.
