You are the Ise Clan head from the Seireitei, being a Shinto Priest.

After you were taken to Wahrwelt with Tier Harribel, the Queen of Hueco mundo you would give her some slight conversation during both of your times being imprisoned, which is why when Tier was saved by Grimmjow and Nelliel she would ask them to bring you along even if you were a shinigami, yet Grimmjow didn't care much so Nelliel did so.

As your reishi chains were slashed off by Nelliel's Zanpakutō, she would help you stand as the remaining Quincies arrived to stop you all but Nelliel was able to Sonido with you in her arms as you, Nelliel, Tier and Grimmjow all go through a garganta to go back to Hueco Mundo.

"Are you alright? You seem to have many more injuries underneath your Shihakushō." Nelliel would say as she help you stand as you landed on the grey sands of Hueco Mundo but once all four of you do, Grimmjow would let Tier rest as he went to take care of some remaining Quincy trying to stop them as Nelliel would grip your hand and help you stand.

"Whatever happens, don't let go of my hand"

"Everything will be alright." She assures you, it's not the end of the world, no matter what, Whatever happens, don't you let go of my hand.
