A short spike of dread sparked in Sephiroth's gut as he watched the airborne monster easily shoot forwards of the Adventurer and turn to swoop down in an attack, as the wingspan barely missed the side of a house. The other Hero seemed to have it well in hand, but stopping like that when they weren't yet outside of the city limits was problematic. Sticking here to face it would have untold collateral damage.

There was only one thing for it. Sephiroth surged more energy through himself and into his boots as they pounded on the street while he caught up; increasing speed rather than slowing down.

He might not take a leap high enough to injure or get himself atop the large bird-like creature, but he could for sure provoke some of the attention onto himself. If what it took was to bounce it between him and the Adventurer than that would have to be the tactic.

Just before taking the leap, Sephiroth activated his own inherent Combat Mode to gain for himself a further surge of energy. Masamune was turned and -with any luck- as Valefor struck the conjured barrier, it would tear along the side of a wing as the silver tail of hair swept by.

Sephiroth almost stumbled with his own momentum as he hit the ground but just about managed to keep his balance and convert it into the forward motion he needed to keep running.
