Cloud was not prepared for this foe that he had been fighting for most of his lifetime. He was surprised to see Sephiroth standing in front of him, smiling and ready for another fight.
"…This is impossible!" Cloud thought. "He can't be back!"
Fear overflowed Cloud and he stopped dead in his track, vulnerable to Sephiroth's attack. Without a warning, a flash of pain had hit Cloud in the shoulder. The pain drew Cloud back into reality and he retreated a few paces back.
"What's wrong, Cloud?" Sephiroth said coolly. "Didn't I tell you already? Even if you're able to defeat me, your DARKNESS keeps calling me back!"
Sephiroth charged at Cloud once again, this time with more aggression and power. Cloud, whose mind was elsewhere, was not ready for this attack. He parried Sephiroth's attack, but Sephiroth's sword was able to cut a few wounds on Cloud's arms. Sephiroth retreated once again.
"You'll never let go of your past, Cloud…" Sephiroth invoked Cloud. "No matter how you change, your past will always come back and haunt you!"
Cloud was enraged and he charged at Sephiroth. He combined the two separated swords into the First Tsurugi again. Cloud swung his First Tsurugi wildly at Sephiroth, determined to shred him into thousands of pieces. Although Cloud was driven by his hatred, Sephiroth dodged Cloud's attack swiftly and dealt another blow at Cloud's shoulder. Cloud yelped out in pain and fell to the ground.
"Don't you understand, Cloud? Even if you're able to kill me, your darkness keeps calling me back…" Sephiroth said calmly. Cloud stood up, planted his First Tsurugi into the muddy ground, and glared at Sephiroth viciously.
"Shut up!" Cloud bellowed. "You've been haunting me for eternity…and now it's time to put an end to this!"
Cloud charged at Sephiroth once again. Cloud performed an upper thrust which sent Sephiroth into the air. Sephiroth prepared to retaliate against Cloud's attack when Cloud's First Tsurugi separated into six swords. The five swords surrounded Sephiroth and Cloud held the main blade in his right hand.
Sephiroth was surprised, but he was ready. Cloud gained speed and charged at Sephiroth. Cloud picked up a sword that surrounded Sephiroth and was ready to perform the technique when something happened that knocked Cloud out of his technique sequence.
A faint light surrounded Sephiroth. Cloud didn't see it at first, but when he saw it, it was too late. When Cloud's blade touched Sephiroth's body, Cloud was knocked backwards by his blade's vibration. Sephiroth had counter-attacked Cloud's attack, and Cloud was now flowing defenselessly in the air. Sephiroth flew at Cloud and performed his most devastating move.
"Sin Harvest." Sephiroth whispered.
An angelic ring appeared on top of Cloud's head. Cloud couldn't do anything to defend himself, so he just waited for the worst to hit him. He didn't have to wait very long. Almost instantly, a dark demonic sphere engulfed his body. Cloud felt like a beast was ripping him apart from the inside. Cloud screamed and fell to the ground. Sephiroth landed smoothly and walked toward Cloud.
"I wonder…" Sephiroth said quietly. "If I kill you, will MY darkness call you back?" He raised his sword and prepared to deal a final blow to Cloud.
Cloud, too weak to react, closed his eyes.
