As the fight was reaching its inevitable conclusion, I sensed that Ulquiorra broke free from the Caja Negacion. From his signature, he went to speak to Aizen before they departed from Hueco Mundo. Like in the original, most likely he was told to hold the fort while they were gone.
Ichigo didn't kill Grimmjow, like in the original.
Grimmjow: Why?! Why spare me?
Ichigo: My instincts are telling me this is not where you are to die. By fighting you, I learned to listen more to what my instincts are telling me.
Grimmjow clicked his tongue and turned his head. In the originl story this was the part where Nnoitra interrupted the ending by kicking away Grimmjow and attacking Ichigo when he was worn out but since he was already taken care of, that did not happen. Orihime was running to to Ichigo's side to heal him but while she gained a gap between us and Ichigo, Coyote Starkk, the Primera Espada (First Sword), used Sonido to flash to Orihimes side and take her away. Before Coyote flashed away…
Sage: I hope you're not thinking you can just take her without me doing anything about it, do you?
Before he could use Sonido to take Orihime away I flicked Coyote's right index finger at him. With an incredibly surprised face, a bleeding missing finger and seeing my grinning face, he took Orihime away. I knew where she was going to end up so there was no worry.
Ichigo: Sage-san! Why didn't you stop him?!
Sado: Sage-san, with your speed there was no way you didn't see him coming. Why?
Sage: To answer your questions, there was no need to do anything. I gave the guy a warning not to hurt Orihime. She is safe by Ulquiorra's side.
Ichigo: We could have just left if she was still here!
Sage: See, that is your head talking, but what are your intincts telling you? Don't you have someone left to kill before we make sure the Orihime we are taking back is complete?
Sado: Complete? (After recalling what I said earlier) Oh! Ichigo, Sage-san did let them take away Inoue but it was for a reason. Go to where Inoue is to finish this and resolve Inoue's inner turmoil.
Just when Sado finished explaining to Ichigo, using Bakudo #77: Tenteikura, Aizen announced where Orihime's location is and that he was going to destroy Karakura Town. I don't know why he sounded boastful in the announcement, they only recovered Orihime because I allowed it.
Ichigo finally understood why I let Coyote take Orihime away, nodded at me and Sado before flashing to Orihime's side. Sado and I followed along only to find Ishida also arriving at the same time. With him being here I spread my senses and found that the four Captains that came were the same as the original story. Byakuya was helping Rukia, Mayuri helped Ishida and Renji, Zaraki was supposed to take care of Nnoitra but he found Yammy instead. As for Unohana, she was looking around to help the wounded. The worst off was Rukia but she appeared after Byakuya killed off the Septima Espada (Seventh Sword), Zommari Rureaux.
While confronting Ulquiorra, Ichigo made sure that he would attack him with everything he had there and then. This time Ichigo was actually hitting Ulquiorra and injuring him. Seeing this, Ulquiorra saw it fit that Ichigo would die to his released state. Ulquiorra gestured at Ichigo to follow him above the roof of Las Noches. I made another couch to take all of us up to the roof so we can see the rest of the fight.
Ulquiorra: This place is above Las Noches. Aizen-sama has forbidden those of the Cuatro Espada (Fourth Sword) and up to release their Resurreccion within Las Noches because we could destroy the palace. This is where you meet your end, Kurosaki Ichigo. Enclose, Murcielago (Bat (Spanish)/ Great Black-winged Demon (Japanese)).
A whirl of powerful Reiatsu was swirling around Ulquiorra. The black and green burst of Spiritual energy fell to the floor like a green rain. Black bat wings formed on Ulquiorra's back, his hair grew wilder and longer and while the remaining part of his Hollow mask was sitting centered atop his head, he grew two large horns extending outward to the sides towards the front. The lines on his face became broader, black and more triangular as he was in the Anime and Manga.
Like my fights, this was outside of Las Noches. All the Espapda Negativa and the resurrected Tousen were above the level of the current top Espada so every time I faced any of them it was like at the edge outside Las Noches. Being outside of Las Noches was nothing new to me. Currently, Ulquiorra was stronger than Ichigo by much. I couldn't tell the difference until I felt the pressure he was giving off compared to Ichigo up close. No wonder Ichigo only lasts a few seconds before Ulquiorra puts a hole in Ichigo's c.h.e.s.t. After lasting longer than intended, Ulquiorra uses his Resurreccion: Segunda Etapa (Second Ressurrection release), completely overwhelming Ichigo and firing a cero through his c.h.e.s.t.
Sado: Ichigo!!!
Ishida: Kurosaki!!!
Orihime: Kurosaki-kun!!!!
After hearing Orihime's voice the presumed dead Ichigo's body, started to pulsate. From the hole that Ulquiorra made on Ichigo's c.h.e.s.t came out a tremendous black Reiatsu. From Ichigo's mouth, white Reiatsu like clay covered his face to form his an advanced version of his Hollow mask. The white clay-like Reiatsu spread to the rest of Ichigo's body, completeing the transformation. Ichigo got up and, like a master Jedi, summoned his Zanpakuto back into his hand. Obviously bewildered by Ichigo's revival, Ulquiorra asked the Zangetsu possessed Ichigo…
Ulquiorra: Who are you?
Ichigo: Rwwaaarrrrrr!!!!!!
Powerful shockwaves spread around the roof. Because of the material make up of the palace, the Reiatsu can only be faintly sensed through the hole that was made on the roof. Ulquiorra fired a Cero Oscuras (Dark Zero) at the newly transformed Ichigo but only to be countered by Ichigo's own Cero. I held Orihime, Sado and Ishida back to not interfere with their fight because Ichigo does not recognize anyone other then Orihime as a friendly. I erased my presence so as not to vere Ichigo away from Ulquiorra. Only when Ichigo finishes off Ulquiorra I will step in to bring him back, maybe.
