Neon White

Heavenly Delight tickets can be acquired by talking to Gabby at the Heaven Central Authority complex located on the right of the Central Heaven screen. You'll need your character at a certain Neon rank (for the first ticket you'll need to be at rank 98), which can be improved upon by acquiring Gold or Ace medals, depending on how fast in terms of time you complete a level in a set of missions. Earn at least two Gold or Ace medals in the levels for Mission 1 (Rebirth), then talk with Gabby after completing the mission to get the ticket. Then go to the Cathedral from the Central Heaven menu, and then select Heavenly Delight Kiosk, and select Redeem Ticket. The achievement will pop on screen after this is done.
