Chakuro is a passionate and curious thinker who seems to always ask questions about the world around him. Some of the most occurring questions he asks are 'how do mud whales float?' and 'why are feelings important?' His obsession with writing is seen as an illness by his grandfather and himself. As an archivist, Chakuro writes objectively which is a contradiction to his expressive behavior. His writings are relied on by the council members. Chakuro is very expressively emotional. It is pointed out that he often cries in funerals when they are not supposed to. (Source: Children of the Whales Wikia)
