Soi-Fon sat up in her bed in the division 4 hospital with bandages wrapped around her torso and her uniform folded up neatly on a nearby table with her Zanpakuto on top of that. Captain Unohana entered the room and was carrying a tray with some food and medication on it and warm smile on her face. "How are your wounds feeling today Soi-Fon?" she asked sitting the tray down on Soi-Fon's lap.

"They still hurt but it won't kill me" Soi-Fon sighed putting her hand on where the gash was on the center of her stomach.

"They won't now at least, if he would have cut you a couple inches deeper, you would be in two pieces right now" Unohana said giving Soi-Fon some pain meds.

"I just don't know what happened to Hikari, it's almost as if he wasn't himself anymore. And to be able to open a portal to Hueco Mundo by himself, proves that something is wrong with him" she said gripping tightly to the sheets covering the lower half of her body.

"And the fallen one he spoke of…who could he be talking about?" Unohana said thinking as the door was opened and Ichigo and Rukia walked in. "Oh, Ichigo, Miss Kuchiki, what are you doing here?" the captain asked kindly.

"We came here to talk to Soi-Fon if that is alright" Rukia asked as Captain Unohana nodded. The captain left the room and it was only the three of them now.

"What do you two want?" Soi-Fon said slightly irritated.

"We came to ask you about Hikari so we could find out what made him attack all of us" Ichigo said sitting Zangetsu against the wall so he could sit down in a nearby chair.

"Any information you could give us would be extremely helpful" Rukia said sitting down next to Soi-Fon.

"Hmph, fine but only to help my friend" Soi-Fon said. "It was 140 years ago when I first met Hikari…"

*flashback*

A younger Soi-Fon was fighting off several large hollows all by herself in her punishment force uniform in a large stone quarry several miles outside of the Seiretei. She slashed left and right at them, cutting the masks of each one with each swing until one of them swung its giant fist at her, sending her flying into a large stone and causing her to cough up blood. She slid to the ground and looked up to see the hollows closing in on her. 'Of all the times for Lady Yoruichi to be away, I had to get sent out to fight these hollows' she thought to herself. 'I guess this is where I die' she said to herself closing her eyes as a howling hollow pulled back its fist to smash her again. The sound of a sword being pulled out of its sheathe was heard along with several slashing noises. Soi-Fon opened her eyes to see all of the remaining hollows were frozen in their tracks as a soul reaper with a blood soaked sword stood in front of her.

"You alright?" she heard a comforting voice say. She looked up to see a blonde, shaggy haired man looking down at her with his deep blue eyes as the hollows before her split in two and fell apart, fading away with the wind.

"What the hell did you do that for!? I had the situation handled!" she yelled at him gripping her left arm on pain.

"My, you sure are a grateful one aren't you? And from what I saw, you were about to become food for those things" he laughed. He put out his hand and helped Soi-Fon to her feet, then handing the sword she dropped back to her. "What is your name?" the soul reaper asked her.

"Lieutenant Soi-Fon of squad 2" she said as he sheathed his sword.

"My name is Hikari Okami, I'm also in squad 2 but i'm new so i only know the captain and 3rd Seat Urahara, its nice to meet the second in command" he smiled at her. Hours passed and Soi-Fon and Hikari had returned back to the Seiretei, Hikari carrying Soi-Fon on his back. They entered the 4th squad barracks to have several relief squad members approach him slowly.

"Is there something wrong?" one of them asked as they saw Soi-Fon on his back.

"Yes, the lieutenant is injured and I would like you to treat her as soon as possible" He said giving her to them.

"Right away sir" they said taking her away.

"I guess I will see you around Soi-Fon" he waved at her as he walked out of the barracks.

*end flashback*

"He saved my life that day, and when I wasn't with Lady Yoruichi I would spend time with Hikari, helping him train to adjust to the way the stealth force operates, but no matter how much I tried, he was still a no good lazy bastard" she smiled a bit.

"That's all nice and junk but this isn't helping us with finding out who the fallen one is" Ichigo said only to have a metal tray thrown at his face, leaving a dent in it in the shape of his face.

"As I was saying, Hikari would sometimes spend time in the squad five barracks when he had nothing else to do and sometimes would hang around the higher ranking officers" Soi-Fon said when she realized something.

"Wait a moment; Aizen was an officer in the fifth squad wasn't he? And didn't Shinji get turned into a hollow by him?" Rukia said

"That's right…" Soi-Fon said standing up from her bed then putting on her soul reaper outfit. "So the fallen one must be the only one capable of turning someone into a hollow hybrid" she said limping out of the room.

"Aizen" Rukia said crossing her arms.

Meanwhile in Hueco Mundo, Hikari stood over a mountain of dead hollows with his sword in its shikai state and his hollow mask on. Similar to his hollowfied form, it had a skull like appearance with red outlines to ever line on the mask and had two large horns on the front of it. He stood painting with several bruises and cuts on him as he removed his hollow mask. "Aizen, you will be freed" he chuckled as more hollows surrounded where he was, possibly thousands. "Bankai" he said turning his sword into a scythe and his uniform into a long black cloak with a black hood. He held his hand up to his face and reformed his hollow mask which turned his eyes black and red. He held out his left and a large black cero began to form in it which he fired at a large section of the hollows, destroying that entire area with large explosions that could be seen for miles around. At seeing this, the other hollows charged at him and he began to slash at them left and right, killing them as if it were nothing. One of them charged up a Cero and shot it at him, only to have the mouth on the skull of his scythe and sucked into the scythe. The blade began to glow as he shot a large line of energy at the hollows, killing the rest of them in one attack. "I think I'm ready now" he said taking off his mask and looking at the pile of ash and bodies around him, smiling at his work.
