As he drove along the road, one thing crossed his mind: What was that flashback that he had forgotten? Cloud closed his eyes for a few seconds, trying to remember who was in that flashback. As he closed his eyes, several images flashed through his mind: A girl with a flower basket, her generous smile, and the only quote he remembered that she said: "You're okay now, right?" Cloud gazed into the distant mountains. "…Who is that girl?" Cloud questioned himself again. Suddenly, the sun disappeared behind thick clusters of clouds. Heavy and rapid raindrops fell restlessly from the sky. Despite the bad weather, Cloud drove on.
"…Where am I?" Cloud thought out loud while guiding Fenrir along a dark, muddy road. It was pouring even harder now, and the mud prevented Cloud from advancing along the road. Suddenly, Cloud spotted an impenetrable fog ahead of him. Being the valor warrior he always was, he guided Fenrir cautiously into the mysterious haze. Cloud could see no more than twenty feet ahead of him, and he began to worry. All of a sudden, a sword slashed through the air toward him. Cloud jumped off his motorcycle and parried the deadly blow with his First Tsurugi. The swordsman who ambushed Cloud jumped a few paces backwards and prepared for another strike at Cloud. The mist began to clear. Cloud separated his First Tsurugi into two duel-wielding swords and charged at the mysterious swordsman. To his surprise, as the fog vanished, he instantly realized who the swordsman was by his clothing.
The swordsman wore a black outfit. On his shoulders were two silver shoulder armors. He was a tall figure, a bit taller than Cloud who was 5' 7" tall. He wore black leather gloves, silver wrist guards and black leather boots. The swordsman also had long, silver hair. His sword was longer, thinner and sharper than Cloud's First Tsurugi. The swordsman's most remarkable appearance was his one-sided wing that was attached to the back of his body.
It was Sephiroth.
