1. Go to ASB mode

2. 2nd page of 'Battle Tendency' and select the battle between Young Joseph and Cesar (Bottom left corner)

3. Repeat this mission until you gain the desired amount of money you want.

*Note: Secret mission 1 ~ Taunt ; This gives 1000 every time.
Secret mission 2 ~ Land a 5 hit Combo

(I pretty much Taunt at the beginning of the match and grab Cesar until my HHA/GHA is full and then use that for the 5 hit combo. Either get S or A rank, netting me almost 2250 every minute.)

HAIL 2 U!
