(Author's Note: Here's a little treat for you! This is a bonus chapter in which Nick and Irma head to Radiant Garden and fight the one and only One Winged Angel! Enjoy!)
Nick and Irma stepped out of the door and into a mysterious canyon that overlooked a massive castle.
"Is this Hollow Bastion?" Irma asked.
"I think it's called Radiant Garden now," Nick noted. Suddenly, he caught sight of someone standing at the edge of the canyon.
"Who's that?" Irma asked.
As Nick studied the figure, he took note of some of his more peculiar features: long silver hair, a sword that was about two keyblades in length, and a single, black angel wing.
"Is that...?" Irma asked softly.
"It is, Irma. That's Sephiroth. Just like Sora told us," Nick replied, slowly and cautiously walking up to the One Winged Angel.
Sephiroth didn't seem to notice the two. Suddenly, he spoke up.
"What is Cloud doing?"
Nick looked back at Irma. "Beats me."
"By the way, you two..."
Sephiroth drew his sword and pointed it towards the two lovers. "Who are you?"
Nick and Irma leapt back and materialized their keyblades. "I'm not sure we should tell you," Irma replied, cautiously holding Mysterious Abyss.
Sephiroth took a good look at the blades these two teenagers were holding. "Well. That's an... interesting sword you're carrying," he said, making a direct reference to the weapons Nick and Irma were wielding.
"It's the Keyblade!" Irma shot back.
"I see... so that's a keyblade," Sephiroth replied. "And I suppose you must be its chosen wielders."
"So what if we are?" Nick asked.
Sephiroth held his sword in a battle stance. "I wonder if it won't change its mind... once I defeat you."
Nick and Irma shifted into battle stances themselves.
"Show me your strength," Sephiroth challenged.
"This could very well be our toughest fight yet. You ready, sweetie?" Nick asked his lover.
"As I'll ever be," Irma replied.
"That's enough," Sephiroth said, ready to attack.
He came so fast that Nick and Irma barely had any time to react. Nick and Irma got their weapons up just in time to block the incoming attack.
"Whoa! He's fast!" Irma exclaimed, turning towards Sephiroth.
"Come on, now's our chance!" Nick replied, holding Oathkeeper and Thunder Striker out and charging for Sephiroth.
Just before Nick could strike, Sephiroth disappeared in a swirl of feathers. Nick looked around for the One Winged Angel to no avail. Until...
"Nick! Look out!" Irma shouted, but too late.
Sephiroth reappeared in front of Nick and knocked him into the air with his super-long sword before disappearing again.
Nick was ready this time, making a quick aerial recovery and using the power of his keyblades to target Sephiroth as he came out of his teleport.
Taking his chance, Nick began attacking rapidly, giving Sephiroth no time to counter. Nick finished the assault with a spectacular Cross Attack that sent Sephiroth flying across the arena.
Nick quickly landed and prepared for Sephiroth's next attack.
"Know your place," Sephiroth shouted.
Out of nowhere, a bunch of blue orbs appeared and directed themselves towards the lovers. Reacting fast, Nick batted some of the orbs away with his keyblades, and Irma used her water magic to douse some of the other orbs.
Sephiroth disappeared again, this time reappearing high in the air. He was glowing an eerie shade of pink and purple. Suddenly, Irma covered her chest with her hand. "I feel kinda funny," Irma said softly.
"Descend now," Sephiroth chanted. "Heartless Angel..."
Irma clutched her heart area, seemingly in pain.
Nick suddenly recognized that attack, racing towards Sephiroth like mad. "Oh, no you don't!"
As Sephiroth prepared to take Irma's heart, Nick leaped up and smacked Sephiroth in the face with the broad side of Oathkeeper, interrupting the Heartless Angel attack just in time.
As Sephiroth dropped to the ground, Nick landed as well, charging forward, intent on showing no more mercy to the One Winged Angel.
Sephiroth held up his hand. "Perish now," he shouted, and many columns of fire rose up around him. Nick quickly scooted to a halt and quickly turned to run in the opposite direction. However, it seemed that the pillars of flame were drawing him towards Sephiroth.
Thinking fast, Nick slammed both of his keyblades on the ground, propelling himself high enough to escape the pillars of fire.
Aiming another attack for Sephiroth, when Nick came down, he slammed both of his keyblades on the ground again, but this time, the impact was so strong that it created a spherical energy field that stunned Sephiroth.
Taking advantage of the lull, Nick raced over to Irma, who wasn't feeling too good.
"Are you all right, sweetie?" Nick asked.
"Something about that Heartless Angel attack... I think he's trying to take my heart..." Irma weakly replied.
"Why would he do that?" Nick asked.
"I think... he's toying with me..."
"I never toy with my opponents," Sephiroth said, appearing directly in front of Irma and swinging his sword. Irma barely got Mysterious Abyss around in time. "I never show mercy."
"That's good to know," Nick replied, switching Thunder Striker with Cassidy's Star. Taking his chance, Nick began attacking rapidly.
But Sephiroth had disappeared yet again, appearing high above the cliff, far away from the duo.
"The time has come for your demise," Sephiroth shouted, launching numerous fireballs for the bearers of the key.
"Oh, crud! MOVE!" Nick shouted, taking Irma's hand and running around the arena, trying to avoid the fireballs.
Once the fireballs had subsided, Nick looked around for Sephiroth, who had disappeared yet again.
"Why does this guy love to teleport?" Nick asked himself.
Suddenly, Irma dropped to her knees, clutching her heart area.
"Irma!" Nick shouted, looking around wildly for the One Winged Angel, but too late – Irma's heart had just come out, glowing a radiant blue.
"The Heartless Angel never shows mercy on the unworthy," Sephiroth explained, reaching for Irma's glowing heart...
...but that was as far as he got before Nick let out a mighty battle cry and struck Sephiroth with both Oathkeeper and Cassidy's Star.
Sephiroth tried to parry, but Nick was too fast, attacking rapidly and giving Sephiroth no time to counterattack.
"How DARE you steal my girlfriend's heart!" Nick shouted, using his keyblades to knock Sephiroth all across the arena like a rag doll.
Showing no more mercy, Nick propelled himself high into the air, attacking Sephiroth on the way.
Once he'd leapt high enough, Nick made his move, bringing both of his keyblades crashing down hard.
After a few seconds, Sephiroth began slowly fading away. However, he had an evil smirk on his face.
"Defeating me is meaningless. The bearers of the keyblade should know that more than anyone. No matter how many times I fall, the darkness keeps calling me back," Sephiroth explained.
Nick, however, simply twirled the Oathkeeper and pointed it towards Sephiroth.
"Then how about I send you to a place where the darkness can't reach you?" Nick shouted, and with that, a bright beam of light shot from the Oathkeeper, piercing through Sephiroth.
As the One Winged Angel disappeared, Nick looked towards Irma, who was laying, unconscious, on the ground. Holding her glowing heart, Nick walked up to Irma and let her heart sink back into her body.
Slowly, Irma opened her pure sapphire eyes and looked straight at Nick. "Did I miss something?" she said softly.
Nick simply opted to embrace his lover, who gladly returned it.
"Did we beat him?" Irma asked. Nick nodded.
Suddenly, a telepathic voice shot through Nick's head.
Nick! Can you hear me? It's Cassidy! I know you might not think it's possible that I'm alive, but you should come to Twilight Town! I'll explain everything there!
Nick's eyes shot wide open. "Cassidy?" he stated.
"Who?" Irma replied.
"Cassidy! My old friend! I think she's trying to contact me! We'd better head out!" Nick exclaimed, hopping to his feet and pulling the Twilight Town world card from his deck. Holding it into the air, a door to Twilight Town appeared.
"Let's go!" Nick exclaimed.
