guys check arena rules
ARENA’s Seasons-
1. In the first day of each month, if you reached Six Paths Sage rank, all your Rank Points will be reset (in order for the player to obtain all the rewards again, including Konohamaru ’s fragments).
2. Players who did not achieve Six Paths Sage rank will not have their Rank Points reset, but they will only obtain the minimum rewards of the Season’s competition. (minimum means ninja school or genin)
