DELTA is a tournament series held in Tokyo, Kantō, that began in late 2022. The series gained wider recognition in the competitive scene during 2023's Golden Week, when its fourth iteration became the second of three supermajor events of the holiday period. Since then, it has became one of Japan's largest tournament series in the post-online metagame.
