Demi and her older brother Sam came to a small town in Europe, and opened a bar. Thanks to that Sam made and started selling their signature wine “Dovlin”, the bar became famous overnight. But Sam found any excuse not to allow Demi to taste it.
Demi reopened the bar to survive, but the customers didn’t return without Dolvin. On her 20th birthday, she received a letter that included a recipe. She followed the recipe, and that formula succeeded to produce Dolvin.
The barmaid carries a bottle of D.U.P.H.R.I.N, which is Dolvin liqueur. When she drinks D.U.P.H.R.I.N, it increases her run speed by 50% for 2 secounds. After she mixes and makes Dolvin, she and other survivors can drink it and cure injuries.
