You decided to join Abarai Renji and Kuchiki Rukia in their mission to Hueco Mundo to save Orihime from the arrancars. You were older than them and had the most experience within combat which means you would be leading in some parts within here despite not knowing the interior. After being separated from the rest you suddenly heard a familiar voice behind you

"You've grown stronger haven't you?" He commented with your strength being much more stronger than before when he was still helping you with your training.
