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

Uniform
All students are to remove their personal shoes, place them in their designated shoe box and wear Uwabaki, a type of slipper, when entering the school building.

Males
For male students, their standard uniform is a light green gakuran, which has two black stripes on the hems (sleeve hems and bottom hems) and black fabric bordering the placket to the top of the collar. Worn underneath it is a white dress shirt with two black stripes on the collar and again on the hems as well. To accompany the Gakuran are light green straight leg pants that have two black stripes on the cuff area and black fabric bordering the entrance of the pockets. The pants should be worn with a dark-colored belt.

In the summer, from June 1st to October 1st, males wear the white dress shirt or a polo shirt (with a similar design as the dress shirt) with a light green tie and the regular light green pants.

Females
For female students, their standard uniform is a sailor fuku. The long sleeve blouse has two black stripes on the hems (sleeve hems and bottom hems.) The sailor-style collar attached to the blouse is light green and has two black stripes at the ends. It is accompanied with a light green pleated skirt.

In the summer, females wear a similar uniform, compared to their standard, but the blouse is short sleeve.

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.
