At the heart of a magical academy divided by seasons, the summer campus welcomes new students to their first class, a lesson unlike any other. Professor Fire, a stern and mysterious instructor, hands out glowing golden grimoires to each student. Yet, when the books are opened, they reveal nothing but blank pages. The students are puzzled, but Professor Fire gives them a simple task: take a nap and write down their dreams. Only then will their grimoires awaken and become their own.

Among the students is Park Rain, a visually impaired girl who has never dreamed her world has always been blank. When she raises this concern, Professor Fire doesn’t dismiss her, but instead hints at a special kind of dream only she can access. Esso, a spirited and talkative classmate, tries to befriend Rain but unintentionally touches on her vulnerability. To make amends, she suggests they explore the underground campus, where it's always nighttime, perhaps the perfect place to trigger a dream.

Joined by the thoughtful Kim Dream, the trio descends into the moonlit underworld of the school. There, they stumble upon an advanced magic class where students are learning to interpret the language of animals. A magical fox alerts the class to the presence of intruders namely, the curious trio. Retreating quietly, the three friends find hammocks hung between ancient trees in the underground forest and prepare to follow their assignment: to dream.

As they drift into sleep, Park Rain clutches her blank grimoire, unsure if sleep will bring her anything at all. But as the quiet sets in, a shadowy presence begins to creep toward her dark, formless, and oddly familiar.

A story of magical education, identity, and the unseen world within dreams, The Dreambound Campus explores how what makes us different may be the very thing that unlocks the greatest magic of all.
