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.
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.
Aside from being academically gifted, the students of Wellston High also tend to have powerful abilities or good grades. Powerless students (called "cripples") and low-tiers are relentlessly mocked and bullied.
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.
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. While this leads to many students improving their abilities and becoming stronger, it also leads to rampant bullying.
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 a vest; John and Elaine are some of the few students in the entire school to wear their vests.
