Gym Gamma (体育館γ (ガンマ) Taiikukan Ganma?), commonly known as the Training Kitchen Land (トレーニングの台所ランド Torēningu no Daidokoro Rando?) or TDL, is a training area in U.A. High.


Gym Gamma consists of a large, empty, enclosed space. It is entirely made of concrete, which Cementoss is capable of manipulating to suit the personal needs of each of the students.


It was created by Cementoss as a place where students could develop new techniques that could be applied on the Hero License Exam, under the supervision of Ectoplasm, Midnight and Cementoss himself.[1] It was used by both Class 1-A and Class 1-B.
