Yu-Gi-Oh! Vrains - Den City High School

Den City High School is a location in the Yu-Gi-Oh! VRAINS anime. It is a high school for students who reside in Den City, equipped with facilities similar to that of a university. The school appears to focus on education rather than Dueling, and teaches a curriculum that includes advanced mathematics and quantum mechanics. The students are often seen carrying an electronic notepad which they often use during their class hours. Teachers also use these notepads to give lectures. The classrooms resemble lecture halls and are equipped with an electronic whiteboard that can additionally be connected to a student's Duel Disk, allowing them to access videos of LINK VRAINS.

Cameras are also hinted to be present on the ceilings of the classroom, as one of such was used to spy on Yusaku Fujiki when he was conversing with Naoki Shima. As stated by Naoki to Yusaku, no student is allowed to have part time jobs.
