1. Go to Treasure Battle
2. Pick your favourite character
3. Rank up until 1st Dan and after that you will have to win around 50 games (Depends of your skill.)
How ranked system works in points after you reached 1st Dan:
You will earn points if you win and if you loose it will go opposite way
Same rank = 1 Point
+-1 Dan Difference = 0.5 Point
+- 2 Dan Difference = 0.25 Point
+-3 Dan Difference = 0.125 Point
And so on...
So after each game you have a choice of three opponents
Pick opponent with the same rank like you, so you will rankup much faster.

P.S. You can also try to choose in game settings easy difficulty and one round, but I am not sure if that would work.
