You have completed all of one characters Challenges!

Each character has 30 Challenges to do. These Challenges start off easy but then get harder towards the end, Challenge 30 is basically a test to see what you have learned. It would give you something like chain in two SP Skills into a combo, but wont give you an input list to do that. Its something you will need to figure out for yourself (or just see Combo Crazy for videos and combo descriptions in order to do that challenge). Or it could be something like do so much damage within a combo. It differs per character. It is always something to do with a combo though. Its not a combo if your combo meter is in yellow, it has to be a true combo that is red, yellow means the opponent could have escaped the combo at some point
