You will belong in an "Arena Division" based on your Arena results.
You will begin from the "Rookie Division". As you continue to get good results, you will be promoted to a higher Division.
At the end of the season, you will receive “Division Rewards” in accordance to your Division. The higher the Division, the more rewarding it is.
With poor performance, you may also be demoted to a lower Division.
※In each Division, there is a fixed number of matches required to participate in a season. Not reaching that requirement will result in demotion, regardless of Rating Points.
