School Anthem
The antenna extends from our school building Hidari Wakibara keeps on going The new leaves of spring are as green as they say Wearing our uniforms, we greet the new day PK Academy, no matter the disaster We'll make it through using an unknown power Ohh PK, PK An everlasting place of learning An everlasting youth

Classrooms
The school classrooms are labeled according to Psychic Zener Card symbols. The first number represents the year they're in and the second symbol is a Psychic Zener Card symbol, each one is used in place of a number. Thus, the classes are label as: 🌕-1|➕-2|∭-3|⬜-4|✰-5. For example, Reita's class is 2 - ➕, where the ➕ stands for 2 so he's in 2nd Year - Class 2 and the ∭ looking symbol for Kusuo's classroom number stands for 3, so he's in 2nd year - Class 3.
