Dohna Dohna - Final Boss
Cleared on Day 69. (I believe that's the least amount of days you can take to clear)
This game has super fun boss fights when you go for a minimum day challenge run (i.e. no farming). The only times you are actually allowed to farm are when you are waiting for required VIP matches or some other story-related event where you don't have to do anything specific. At the endgame (when waiting for the final VIP match) I opted to farm Shipyard for Level 5 Weapons rather than gaining levels at Anepic, then I was only able to afford them by constantly restarting until they were all on sale at the same time lol. The biggest annoyance about playing this way is that you have to restart A LOT during hustling so that you can get good clients. Make sure to buy MP items whenever available at the shop because I didn't do that for most of the game and it bit me in the butt here.
