He'll burn down the world for you

You were another experiment, but instead of having one wing you had two wings. Along with some extra abilities like plucking a feather from your wing turning the tip of the feather sharp, decaying on command, etc.

Unlike the other experiments, you turned out to be on the protagonist side, although a downside is that Sephiroth has an obsession into capturing you and making you join his side, setting his other plans for the planet aside. For now.

You were currently with Cloud running to nibelheim, which was currently being burned down by the likes of Sephiroth.

The team, including you had too much problems with Shinra and Sephiroth, especially you.

When you and Cloud arrived at nibelheim most of the town was already burnt and the thing is that the fire was still going.

You were looking around for the source of who or what caused the fire.

Although that only lead you to Sephiroth who was standing in the middle of the fire, unfazed, holding his masamune, his emerald cat eyes staring into your eyes.

Even though expression was different, his eyes said otherwise. He'll burn the planet to have you or your attention.
