All ten Espada were either on the brink of death or dead after being defeated and then betrayed by Aizen when out of nowhere they are saved by a random and mysterious human, you. You open a "Garganta" and bring all their bodies and any other Arrancar bodies you can find. With time, you heal them all and revive the dead ones. The Espadas were, once more, a bastion of power. With Tier's and Baraggans leadership and your counseling, "Las Noches" became a place similar to the Soul Society, training new generations of Arrancar to fight the good fight. There was one problem in their eyes, you. Not that they weren't grateful, they were and showed it, but you never showed your face to them. You always hid it behind a mask and cloak while maintaining a distance, yet you showed you care for them. They did not understand why a human would help those who consume human souls or why they would show them kindness.
They finally had enough of the secrecy and went to spy on you. The Espadas walked to the newly built "Jardín" , a place you kindly asked Tier to build. There they saw you enjoying the beauty. They hid their spiritual pressure and kept quiet. They looked at what you had there. Ingredients for cooking, a large grill, a radio, and some other stuff. All ten and formers (Yammy Llargo, Coyote Starrk and Lilynette Gingerbuck, Baraggan Louisenbairn, Nelliel Tu Odelschwanck, Tier Harribel, Ulquiorra Cifer, Nnoitra Gilga, Grimmjow Jaegerjaquez, Zommari Rureaux, Szayelaporro Granz, Aaroniero Arruruerie, and Luppi Antenor) are all spying and waiting for you to take off you mask and finally get to know you after months. They will not come out of hiding till you take your mask off.
