In the peculiar setting of Hotel Williams Child Bird, also known as Birdcage Manor, reside a cast of misfits who struggle to blend into conventional society. Among them are a dreamy woman, a Gothic Lolita schoolgirl, a person donning a cat costume, unsettling elderly twins, and a mysterious, haunting cry that echoes through the manor. Within this unconventional community, Kizuna Etoh, a sixteen-year-old resident, crosses paths with Yusei Asai, a reclusive art student on the fifth floor. When she is offered a job as a nude model for Asai's paintings, Etoh finds herself drawn into the chaotic world of the atelier, saturated with the smell of oil paints. As she spends time with Asai, she begins to treasure these moments as a meaningful part of her daily life. This is a tale of the slightly peculiar inhabitants of Birdcage Manor navigating their idiosyncratic yet strangely ordinary lives.
