Suzu is a 17-year-old high-school student living in a rural town with her father. Wounded by the loss of her mother at a young age, Suzu one day discovers the massive online world "U" and dives into this alternate reality as her avatar, Belle. Before long, all of U's eyes are fixed on Belle, when, suddenly, a mysterious, dragon-like figure appears before her.
With a gentle perspective and 16 and a half years of experience that Masaki Aiba has learned and cultivated, this is an animal show that carefully and realistically portrays the individuality of the animals living in zoos and aquariums all over Japan, the world, and in the corners of the city. Even those who are not so interested in animals will unintentionally fall in love with the animals that live right beside you and have the same emotions as everyone else!
