# Beyond the Sea Single Championship

The Beyond the Sea Single Championship (BEYOND THE SEA SINGLE 王座 or BEYOND THE SEAシングル王座, Biyondo za shī shinguru ōza) is a women's professional wrestling championship owned by the Seadlinnng promotion. The title, which is situated at the top of Seadlinnng's championship hierarchy, was introduced on October 3, 2018, and the inaugural champion was crowned on November 1, 2018, when Nanae Takahashi defeated Arisa Nakajima in the finals of an eight-woman tournament. The bottom part of the belt is blue as it resembles the ocean, while the upper part of the belt is red, which resembles the sun. The title was vacated once as a result of former champion Yoshiko taking time off to rehabilitate nagging injuries.
Like most professional wrestling championships, the title is won as a result of a scripted match. There have been nine reigns shared among seven different wrestlers. The current champion is Veny who is in her second reign.
