Vincent, though invisible, had also been near the edges and back given he was not suited for melee and it did not affect a gun's range much. The wind and flames were decidedly unpleasant in his already weaker state--and if he hadn't been aware of Chaos within him stirring before, he very much was after the Bard's song.

He knew that voice; Lucrecia was not here but there were others of those he counted as friends and allies in danger. Driven to his knees and knocked from his Stealth position by the attack, Vincent curled in on himself further as his Limit Break took over. Darkness seeming to engulf his figure before two great wings burst from it, lined in red. A demonic figure emerging that bore a faint resemblance to the foe they were now facing, though not nearly so large nor as dangerous.

Not to the other Heroes of Light anyway, as they were counted allies. Crimson-eyes that were familiar and not surveyed things as a different Chaos took wing. Guided loosely by Vincent's will, the first priority was gliding and swooping to gently grasp and help Rialynn, currently singing, back up. Holding her carefully, placing her away from the flames but near the others, before heading for the boss, Chaos, to attack with Chaos Saber.
