Grimmjow was leaning against a wall, hands in pockets and looking into the distance with a scowl on his face. He hated this place so much, he wished he could leave however he'd learnt better than to mess with Lord Aizen, Grimmjow secretly couldn't wait for the soul reapers to defeat Aizen, it was only a matter of time and that Ichigo kid had a lot of spunk, something told Grimmjow he'd go far.
Sachi had just gotten back from a long mission in the human world and she had missed her squad, she straightened her lieutenant badge as she made her way to her barracks. She wanted to take of flash stepping there but she didn't want to show anyone how anxious she was to get back. When she finally arrived she greeted her squad members, hugged Renji and then continued to the Captains office where she threw the door open with a grin, "Nyah, Bya-kun I'm back~" Sachi and Byakuya were childhood friends, when the were children Byakuya use to get into a lot of fights because other children would pick on Sachi, in the end Sachi decided to learn to fight her own battles and followed Byakuya becoming one of his lieutenants.
