To keep track of what missions your character has done, create some type of record in your character profile to keep track. For example, this format would work fine:
D: 0 || C: 0 || B: 0 || A: 0 || S: 0
Of course, you can format it however you wish. As long as it shows your character's mission records clearly.
The Tournament of Villains (Maybe?) [Coming Eventually!]
