The summon was sharp indeed, sharper than any run-of-the-mill monster that was for sure; to have changed it's position as if it knew he was coming - Sephiroth felt lucky that his sword had even managed to nick at its tail and soon found, with a quick glance over his shoulder, that he needed to near enough dive for the pavement to miss the counter-move as the appendage tried to fend him off.

It seemed that the Adventurer had gotten its attention again, and Sephiroth took a moment to gauge the situation as Cloud's dark energy spell surged in from back a ways. Heaving a little in his breath, though it felt strong to do so and not tiresome at all. Between his mako-energy levels and the Echo on top, it was already likely that he'd probably be able to go for hours yet. Sleeping might even prove to be an issue tonight.

As the Aeon lifted itself higher into the air, and flew off pointedly away from the Heroes, Sephiroth drew himself back up to his feet and craned his neck up, looking around to at least try to get the bearing that the giant bird-type creature had flown in. The Adventurer could jump from roof to roof all he wanted; Sephiroth wasn't about to take that much of a risk chasing something down.

Better to wait for the others. Sephiroth eventually turned back to where the others had lingered back further, closer to Yuna's residence. Turning his long sword around and tucking Masamune back up the underside of his left arm again as he strode closer.

"Well, she's out of here now. Any ideas?"
