Binzume Yousei is a delightful fairytale that unfolds in the year 2004 and features four captivating fairies at its forefront. Each fairy has a distinct color that corresponds to their magical bottle jars. There's the vivacious Kururu, the reserved and elegant Chiriri, the adventurous and samurai-loving Sarara, and the quiet and enigmatic Hororo. These fanciful fairies are completely fascinated with the human realm, and thus they leave their fairyland to partake in human traditions and integrate into human society. Though they possess minimal knowledge of human culture, they fortunately encounter two important friends- "Sensei-san," their college-aged roommate, and "Tama-chan," a pure-hearted first-grader who is every bit as innocent as the fairies themselves. Despite their strange ideas and challenges in grappling with this new world, these bottle fairies strive to relish and treasure their time amongst the humans, always finding endearing ways to make their lives more delightful.
