Toya is a little boy, who escaped from his strict, abusive father, when he discovered a peaceful, colourful world of lively youth. Ever since then he’s been staying there happily, with the companions, who live there, who take care of the little boy despite being animals. The Purosekai he lives in is disconnected from the real world after all. He’s small and short, due to his very young age, as he’s still in his childhood stage of life, but old enough to be able to read, write, speak and walk.
