Vali likes to do his own thing and not be tied down by a position. Him creating his own magician brotherhood means he can help the world while having the freedom as its leader to do whatever he wants at his leisure. As Vali will be so strong there won't be a need for him to fight really and he can leave strategy to his second-in-command who no doubt he will recruit such a person to be able to lead Mizunoe. He's just a guy who enjoys ramen and fighting strong people. I would imagine Lavinia being his advisor, always complaining how too laid back he is and that he has to take many responsibilities. He's a white Sirzechs but is actually a Lucifer. Even Vali himself would say Issei is better suited to be a Devil King as Issei is a person who likes to take positions for responsibilites of the greater good, regardless if it gives him less freedome to do things.
