Little Shark arrives at Yagyo Station and encounters Sora, a girl sitting sadly on a bench. Sora tells him she's transferring to a high school in the city and is worried she might be all alone. Little Shark encourages her, showing her a magazine with pictures of the fun city life and telling her she'll surely make new friends there. After parting ways with Sora, Little Shark starts walking and his eyes are drawn to a glittering poster of the city. At that moment, a shark-shaped cloud passes over him. As if drawn by the cloud, Little Shark boards a train bound for the city. Shining neon lights, a scramble crossing where people come and go, a crowded train swaying with many people. Little Shark's little grand adventure begins in the city.
