"Burn, Phoenix of the Su-!"
The unfortunate Soul Reaper did not get to finish his statement, for a black arrow pierced his neck. Hundreds of Soul Reapers surrounded Sandro, but none of them could hurt him. He was a master of Spirit Pressure and Particles. He could crush their heads with a hand movement. His favorite thing to do was to grow wings and snipe them from up high. He was good, but in the distance he heard something with "Hime" in it and a red blast came very close to his head. Another Arrancar blocked the blast.
(Ulquiorra) "Trash…Barely worth blocking. Aizen-Sama requests your presence."
(Sandro) "Very well"
They sonidoe'd out of there and Ulqui opened the portal to Hueco Mundo. But, out of the corner of his eye he saw someone beautiful with spirit pressure competitive with Ulqui's.
(Sandro) "That concludes my report father."
(Aizen) "Good, have a rest, my son, maybe go to the world of the living?"
(Sandro) "Yes father."
He went to the world of the living, disguising his spirit pressure, he searched, but he couldn't find her, and even if he could, he still had this Hollow-Mask fragment on his forehead.
(Sandro) "ERgh…Gragh! Dammit!"
He tried to tear it off, but he couldn't, it was attached to his skull. He wanted to be human; he wanted to be normal, he wanted…
(Sandro) "Whoa"
Suddenly, he was in a large, gloomy castle and opposite him was a person wearing traditional Quincy attire who looked a lot like him, without a hollow mask.
(Sandro) "Who are you?"
(????) "I'm you, if you were human, when you were human.
(Sandro) "I was…human?"
(????) "um-hm, and, you can be human again, if you just let me do this one thing."
