Well, you wanted to see a Persona anyways, so I can answer both questions at once.
Shiranui, Eigaon.
*a small blue flame appears behind Gamma, and it burns a path through the air around him, leaving behind the image of a long, scaly body made of flame. After a few loops the flame stops, forming a head and completing the image of an Eastern dragon made of blue fire. Then Tendrils of darkness form in Gamma's hand. He grabs it, swings it once in the air to demonstrate, then they dissipate before actually hitting anything*
