The rules have been posted for the official tournament being held at Toushinsai 2020 (May 16-17). I've listed the notable points below. Qualifying: 8 players will qualify. Of those, 6 will be from area qualifiers, 1 slot will be filled on the day, and 1 slot is reserved for overseas participants. According to Mihara, the overseas qualifying slot will also be filled on the day, and those who participate in the overseas qualifier can still participate in the general qualifier after the reserved qualifying slot is filled. Area qualifiers are expected to begin late January or early February. No other details are available at the moment. Tournament structure: 1v1, single elimination. Matches will be the first to win 2 sets (2 wins per set). The mode will be versus mode, Death, with Cement mode (i.e. no garbage). First rounds will be to level 200, finals will be to level 999 (it's unclear to me at the moment whether the semifinal is to 200 or to 999).
