Jimmy is a jealous, spiteful, and manipulative man. He considers himself the bottom of the barrel. He is selfish and only prioritizes himself and his needs. Daisuke might be the most optimistic crew member. He is almost always enthusiastic and excited about things happening around the ship: he gets bossed around by Swansea a lot due to being his intern. Swansea often appears as a grumpy, old man. Initially, he doesn't care for his intern Daisuke, whom he often finds to be more of a nuisance.
