This is a tough one. You have his two subordinates, and then maybe their two equals in DN Luke and Kun... This a tough one but when you have 4 people that powerful they would have to take Ragnos. Then again with their combined force abilities and what not, I don't think they'll work together nor give each other room so if that happens Ragnos takes it. But pitting 4 of the most powerful users against 1 MOST powerful, isn't fair.
