Ash is trying to do his own thing, while there is another group going for the "revive Orochi" objective. Ash had some kind of mission assigned to him by Elizabeth, but he decided to scrap that and be fabulous, thinking a purple flame matched his nails.
Also, Rose B***stein (lol, they never *officially* said she and Adel were Rugal's kids, hur hur. And really, the idea of Rugal having kids is just lulz anyways, though still pretty epic.) is going to probably be XII's first boss.
