STEP 1: Place the Pran to delete in central Pran;
STEP 2: Go to the character selection screen and create a new character;
STEP 3: Logue this new character and team Pran him;
STEP 4: Go back to the character selection screen, and then delete the character he had created.
Ready! Now just wait the 3 days for definitive exclusion of the character (remembering that Pran is equipped in this character, so she tb will be deleted along with the char). After exclusion definitive character create a new character, and redo the quest of Pran with it. Bingo!! You've got a new Pran!!!
