Despite possessing an exceptional gift for perceiving the unseen, Wakaba's visions often involve malevolent entities that cause harm to those around her, leading to her isolation and loneliness. Her solace comes from caring for stray animals, but her parents forbid her from adopting them due to her tormented state. Eventually, moved by their child's suffering, they finally relent, allowing Wakaba to keep the next animal she rescues. This fortunate creature turns out to be Pupipo, a pink and charming monster with inexplicable powers that shields Wakaba from evil spirits. With the help of her new ally, Wakaba gains confidence, finds a new friend who shares her fascination with the supernatural, and stands up to bullies. Pupipo transforms her previously bleak and solitary existence, bringing her happiness and enlightenment.
