1h ago Devil's Nest Lowest Level (11:00 pm)
Aizen sat in his cell in silence as he was trying to think of a way out when he heard an explosion from outside. When he looked out his cell door he came face to face with an Arrancarr with a number 4 tattooed on his right hand.

"Lord Aizen I have come to set you free," the new number 4 said as he opened the cell door as Aizen stepped out he saw the dead guards. The number 4 handed him a change of clothes and he changed and made his way to Huco Mundo.

Karakura Town (Ichigo's Room)
Ichigo was on his bed reading when Rukia came in with a worried look on her face. "What's wrong?" Ichigo asked as he walked over to her.
"Ichigo Aizen just escaped prison last night with some help. We need to go to the Soul Soicety now," Rukia said as she grabbed Ichigo's wrist and used his badge to turn him into a soul reaper and dragged him to the Soul Society.

Soul Soicety (Outside Devil's Nest)
When Ichigo and Rukia arrived at Devil's Nest, they weren't the only ones there: Grimmjow and Nel stood there and to Ichigo's delight so was the captain of Squad 10, Toshiro Hitsugaya.
"Hey Toshiro, so any news on what happened?" Ichigo asked as he walked over to stand next to Toshiro.
"That's Captian Hitsugaya to you and no not really," Toshiro said, "however, I've been selected to pick a small team to go to Huco Mundo to retrieve Aizen since his breakout," Toshiro said and Ichigo smiled.
"I got it I'll be on your team," Ichigo said.
Toshiro was about to decline, but Ichigo didn't give him the chance because he grabbed his wrist and dragged Toshiro away which made the white haired captain's face turn slightly red. The reason he didn't what Ichigo to go was so he wouldn't get hurt, yet the reason Ichigo wanted to go was to keep Toshiro safe.

The rest of the day Ichigo and Toshiro picked out the rest of their team which consisted of Rukia, Grimmjow and Nel. Toshiro wrote Rangiku a note to tell her she was in charge while he was gone on this mission and not to stink up his office with her sake. So the next morning they set off to Huco Mundo little did they know Aizen already knew they were coming.

Hueco Mundo(Aizen)
"That's right come this way," Aizen said as he set his trap in motion as he watched Ichigo, Toshiro, and the rest of their team flash step through Hueco Mundo towards the fortress known as Las Noches.
