Heh, yeah, I've seen a lot of people have to go through a lot of crap due to their managers. Isabel kept getting pitted against criminals and such and in the end she just had enough of it.

Underground dueling is an area I've seen a few friends of mine fall into in the past. There was some guy who came to the school once as a manager, but he was trying to get people to join underground dueling. Those were the sort of people Ryuuji and I really wanted to stop and one of the reasons Ryuuoumaru's goal existed. They either make people believe that's their only option and that's what they have to do to be strong enough for the pros.
