At Under Zero─── Go forth, and seize it.
◆ Under Zero ・Established by wealthy elites who grew bored with the modern martial arts world's obsession with "safety" and "sports business," which led to numerous banned techniques. It serves as entertainment for these elites, who watch fighters engage in ugly struggles for prize money.
◆ Rules ・The ring mimics those used in professional wrestling. ・Carrying any weapons or equipment is prohibited. ・Killing is prohibited.
・All other banned techniques (besides killing) are abolished. ・If a fighter suffers a major injury or mental breakdown, Aika will declare a forced defeat at her discretion. ・There are no restrictions on attire, provided it is not weaponry. ・There are no rounds, time limits, or weight classes.
◆ Ranking System ・Winning increases points, while losing decreases them. ・Rankings are determined by points, and the top five fighters receive prize money at the end of the season.

◆ Specialty: None ・Performs dynamic, visually appealing moves like those in tokusatsu hero shows or action movies.
