A league will be held featuring 6 top-class players from outside Japan.
In Oiu League rankings, this league is equivalent to A Class, so the top players can participate in the Master class.
All matches will have commentary and analysis.
The goal is to help more Japanese people become familiar with international players.

Selection Criteria

This time, we will use Ascension's rating system to determine the 6 players of the league.
The ratings as of Oiu League application deadline (20 October) will be used.

Connection Issues

*Details are yet to be determined.

Tardiness

If a player does not appear within 10 minutes, they will be considered late, and the match will be canceled. The match will be rescheduled.
If the tardy party notifies the opponent and they agree, the match may proceed even if the player is more than 10 minutes late.
The decision is entirely up to the opponent. They may choose to cancel the match for the day if they wish.
If a player is late without notifying twice, they will be disqualified.
Even with notification, being late three times will result in disqualification.
*Keep in mind that both players have cleared their schedules for the match, so please be considerate.
*We apologize to those who are inconvenienced by tardiness, but rescheduling the match is preferred over giving a default win, as it may impact league standings.

Misconduct

Players who are found to be engaging in excessive misconduct on social media, trolling, disruptive behavior in the game, or harassment (depending on the severity) will be banned from Oiu League.
*Whether a ban is issued will be at the discretion of the organizer, Piponeer.
*If you feel you've caused trouble in the past or behaved poorly, please be more mindful going forward.
*Keep in mind that social media is visible to many people. Making others uncomfortable is not ideal.
