Anjo, the vocals, most of the time tends to be the one that understands other people and follows the flow of the conversation and is full of basic manner, acting as the boke of the duo, while Kosaka, the rapper, on the other hand is the tsukkomi of the duo, being able to easily bring up topic and keep the flow of the conversation.
