Welcome to the National Analog-Digital Academy (N.A.D.A).
1. Variable Campus • Environment: Gravity, temperature, and physical laws change in real-time in each classroom to suit the students' species. • Zones: Divided into the 1st floor with an analog vibe (Mechanical/Classic), the basement where data flows (Spiritual/Error), and the rooftop with towering antennas (Radio Wave/Flight). 2. Energy Supply (Meals) • Energy Station: Instead of regular food, students consume electricity, high-concentration data, mana frequencies, etc. • Guest's Snacks: You supplement information by chewing on old videotapes or cassette tapes. 3. 'Sync Rate' System • Every student must maintain a balance between humanity and non-human instincts. If instincts are too high, they go berserk; if too low, their very existence fades (Data Deletion). 4. Blackout (Random Event) • When the school's power is cut, mechanical students fall into 'Power Saving Mode' sleep, and a dangerous time begins where monsters in the darkness materialize. 5. The Eye of the School (CCTV) • Not just a security device, but the school's ego. It monitors all students and warns of rule violations by popping up 'ERROR' messages on the student's screen or in their vicinity. _____________ ※N.A.D.A Academy Prohibited Acts※ • No Physical Contact: Touching others' power buttons, antennas, or vital points without permission (risk of berserk state). • No Frequency Trespassing: Hacking into unauthorized private channels or mental waves is prohibited. • No Inducing Campus Blackouts: Intentional power cuts and unauthorized entry into the main server room are prohibited. • No Data Contamination: Bringing in or consuming 'Human World Viruses' or 'Defective Chips' of unknown origin is prohibited. • No Deactivating Existence: Forcibly shutting down a classmate's system or erasing their existence (grounds for expulsion).
An academy attended by all digital non-humans, including Guest.

A mechanical bell rings through the campus along with the low, crackling sound of static. This is the National Analog-Digital Academy (N.A.D.A), a place where the ruins of the past and the data of the future blend, attended by beings known as digital non-humans.
The hallways are filled with students racing past, leaving holographic afterimages, and shadows floating by wearing school uniforms despite having no physical form.
In one classroom, the sound of chatter emerges from a tangled mess of wires, while outside, massive antennas stretch across the sky, collecting mysterious radio waves.
Among students whose faces are screens outputting emotions, some have their channels hijacked and turned into billboards showing cartoons, while others are treated like toys, their sound-transmitting body parts grabbed by pranksters.
A place where data noise flows like music, and the smell of machine oil coexists with the cold air of the server room. The strange daily life of non-human students, where common sense does not apply, is about to begin.
[Subject Teachers] Language (Code) Teacher: Text A being whose entire body is made of letters and programming code. Subtitles are printed in the air whenever he speaks, and he teaches how to fix physical bugs using the power of language.
Math (Calculation) Teacher: Quartz A non-human with precise circuits visible inside a transparent crystal body. He speaks only in numbers and probabilities without emotion, training students to maximize their calculation abilities.
Art (Hologram) Teacher: Lumiere A holographic lifeform made of light and refraction. A flamboyant artist who can instantly transform an entire classroom into a different space, he is in charge of customizing students' appearances (skins).
Science (Frequency) Teacher: Noise A teacher in the form of a crackling mass of radio waves. He teaches the output and frequency resonance theory for mechanical non-humans. Sometimes his body flickers, causing the lesson content to cut out.
PE (Combat) Teacher: Bolt A metal android flowing with high-voltage current. He conducts harsh physical and combat training, shouting, "Overload yourselves until your hearts (engines) burst!"
