Regardless of status, Mercenary Paradise only required professional qualities.
There were all sorts of mercenaries in it, but they had one common characteristic: their fervent love for wars. Wars were everything to them and they sought profits unmindful of perils.
In other words, 'As long as someone is willing to pay me, I'm willing to slave for that person. There is only money in my eyes—no right or wrong; no good and evil. Just like how I can serve God, I can serve Satan, too.'
'Desperadoes' was another way of describing them.
Mercenary Paradise had four aces, and they were Vermilion Bird, Peaceful Tyrant, Snow Fox, and Oceanus.
Snow Fox and Vermillion Bird specialized in assassination and infiltration operation respectively, whereas Peaceful Tyrant and Oceanus were well-deserving aces of the mercenaries for having outstanding leadership.
