It is unclear if Uru-chan was inspired by the real-world Wellston Public High School in Wellston, Ohio.
Wellston High appears to be made up of several blocks. The classroom blocks are multi-storied buildings made of many classrooms connected by halls lined with lockers and windows. Some of the known blocks include Wallik Hall,  Whesley Hall, and Manner Hall.
There are also the dormitories, which are separate from the main school building. They are separated into girls and boys dormitories. It is not known if there are any co-ed dormitories. Those with similar power levels usually share the same dorm.
The Wellston cafeteria is also a prominent location within the school. It is famed for the rare and delicious Triple Chocolate Cake served once a month, which has become the subject of many disputes and conflicts.
The school library is a popular place for students to study, research or simply use the computers. The library is lined with shelves containing every kind of book, tables for students to sit at, and computers for student usage. Looking after it is the formidable school librarian.
Wellston High School is presumably near Kovoro Mall, since many of the students go there on outings over the weekend.
There are around 500 students attending Wellston High. Most of them tend to have powerful abilities and/or good grades. There exists a misconception that every student that attends is powerful. On the contrary, the school does permit powerless students (called "cripples") and low-tiers to attend. However, these lower-ranking students are relentlessly mocked and bullied, making it potentially dangerous for them to attend.
Most students live on-campus in the school dormitories. John was the only known student to live off-campus, until he had to eventually move in with Blyke by the schools orders. It was later revealed that Arlo lives off-campus as well.
A ranking of the Top 10 students in Wellston High was a bonus in UnOrdinary #35. Seraphina is first, followed by an unknown student heavily implied to be John. Arlo, Remi, and another unknown individual (later revealed to be Cecile) fill the third, fourth, and fifth places respectively. Blyke & Isen are sixth and seventh, followed by three unknown individuals (one of which is very likely Zeke in the eighth spot, and the tenth spot is confirmed to be Holden, but the ninth spot remains completely unknown.)
List of Named Students
The staff of Wellston High is comprised of many powerful high-tiers and elite-tiers, as they are shown to be able to intimidate the already powerful students.
Policy on Abilities
Wellston has a very unique policy regarding the usage of abilities, likely due in part to its high concentration of elite-tiers, high-tiers, and god-tiers. Students are allowed to freely use their abilities on school grounds, as the damage is easily repairable, unlike in most places. As a result, fights are very common. This is both positive and negative. Students may use this rule to develop their abilities and grow stronger, however, they can also take advantage of it to use it as an excuse to take part in bullying other students.
Like many private high schools, Wellston has its own uniform. Typically, uniforms consist of a white button-up shirt, a dark navy blue tie, a grey vest worn over the shirt, and a teal jacket. Girls often tie their ties into bows while guys tie their ties into traditional neck-ties and wear their ties under their vest. Girls generally wear dark blue miniskirt and black thigh-high socks while guys wear long black pants.
How the uniforms are worn often varies from student-to-student. A vast majority of students choose to omit wearing their vests; John and Elaine are two of the few students in the entire school who still choose to wear their vests.
