Perhaps it had been a result of the electricity which had dulled out a lot of Sephiroth's senses at the time, that he hadn't been able to fully take in Terra's transformation in the moments he'd been stuck on one knee before her but he couldn't ignore the predatory red eyes that fixed on him in the moments before he made his move. It turned out, that she ascended into the air as he succeeded in stretching out his battle stance once more in front of Maduin - quickly noting the holes that were riddling his sides and the powerful tail which dismissed his attackers as if batting away insects.

The mako that had ensured Sephiroth's survival from that attack now pounded fiercely beneath his skin, within all the fibers of the muscles that worked to keep him standing let alone battle-ready. The silver warrior took a breath as the last tingling of the shock receded and he fixated his attention on that tail which was being used to swat away Imperial troops. His eyes and his focus both charged with the borrowed energy of his own Planet.

A breath exhaled and he dashed forwards as if on the very air itself, only touching the ground again once he was well within range and then planting both feet firmly and powerfully bringing his overlong sword down and around to deliver the most momentum possible in a single slash.

"Argh!"

Sephiroth pulled Masamune up in a great slash, aimed for the meat of the tail as close to the base of Maduin's form as he could call it. Not hesitating with the follow through he launched himself from a deep squat and made to use his own weight to ensure the tail would break entirely whilst at the same time using it as a step to propel himself higher up the body of the monster; better to get a chance to deal a lethal strike next.
