This is a request for Kimi Shiro-Chan. Enjoy :)

It was very rare for Jyuushiro Ukitake to be sent on a mission to the Living World – much less by himself. At the very least, he was almost always accompanied by his two Third Seats. However, this time, with the repairs of the Seireitei looming over everyone, most of his Division had been busy with other things, and his best friend, the Captain of the Eighth, was overseeing his own squad members as they helped out with the damage.

In fact, the betrayal of the Third, Fifth and Ninth Captains had caused so much mayhem, Ukitake was forced to take on a mission that could be dangerous to his already-frail health. He was supposed to take care of a group of Hollows, but there was always the danger of him falling victim to his illness, one of the reasons he was not usually sent on solo missions.

Taking care of the Hollows had been easy enough, his sickness not getting in the way for once. However, just as he was about to return back to the Soul Society, a familiar reiatsu washed over him, so thick with malice, it felt as if he were drowning.

Jyuushiro dropped to his knees, grabbing his head, his own reiatsu flaring instinctively, the immense mass fighting against the other. He was one of the oldest, strongest Captains of the Thirteen Court Guard Squads, and not many could rival his spiritual pressure.

However, Sōsuke Aizen was one of the few who could even outdo his. Gin Ichimaru and Kaname Tosen accompanied the brunet as they walked towards the white-haired Captain. Aizen looked at calm as ever, stopping just a few feet away from Ukitake.

Ukitake was instantly on his feet, Sogyo no Kotowari in Shikai form. He tensed, knowing that no matter how strong he was, he was more accustomed to fighting alongside the Eighth Captain and, without him, he was not strong enough to face three other Captains – one of who had much more reiatsu.

"Captain Ukitake, it would be much easier for us if you'd come along quietly," Aizen said, soft-spoken as always.

"Why?" Ukitake stepped back, his body tense. "You almost got my subordinate killed and betrayed us all. Haven't you done enough to us?"

"If I take one of their strongest and most loved Captains, they'll all be left in devastation," Aizen explained. "They won't know what to do. They'll all run around and leave openings. It's all part of my plan."

"Plan?" Ukitake's eyes narrowed. "I don't want any part in this plan of yours, Aizen. You've done enough."

"What a shame." Aizen's hand travelled down to Kyoka Suigetsu, grabbing the Zanpakutō. He raised it, smiling as he usually did. "It's too bad that you're already in my illusion, Captain Ukitake. Shatter, Kyoka Suigetsu."

Ukitake didn't know what had happened; one second, the three traitors had been standing in front of him, and the next, they were behind him, Gin Ichimaru's Shinso impaling him through his chest. Coughing up blood, he fell to the ground, his eyes wide as he tried to understand what had just happened.

Aizen's expression didn't change as he leant down and lifted the injured Captain into his arms. Tosen grabbed Sogyo no Kotowari, pulling it from its wielder's hands, as Gin opened the garganta, allowing them to head back to Heuco Mundo.

Ukitake struggled weakly within Aizen's arms, but his already-damaged lungs couldn't handle the blow he had suffered, forcing him into a very weak state as throat-tearing coughs ripped their way from his throat, adding more blood to the mix.

Aizen didn't even so much as glance down at the Shinigami in his arms when the older male fell still, weak, barely audible and strained breaths making their way out of Ukitake's chest. He instead made the trip back to Las Noches with his two comrades in tow.

The last thing Ukitake had thought before he had slipped into unconsciousness was that, for the first time in a long time, he was scared, and he wanted his best friend.
