There is one odd person out with 4 fights at the end while everyone else has 5 fights...
The way this last battle will be selected is that this last remaining person will fight someone with the nearest number of total points by that time of the pvp tourney. If there are multiple people with the same number of "nearest number of total points" then he/she will fight the person who signed up the earliest. Should this person who is fighting for the 6th time wins, he/she will receive a "jewelry box" for winning.
