The moon began to shake beneath all of the combatants feet. No doubt something was going on, and it was big. As the moon shook the surface would have started to crack and split.
Perseus struggled against the grip of the female arrancar. He wasnt the most physically fit individual so he couldnt get out of her wounded grip. Staring up at a charging Cero. Then in a flash everything went black. But it wasnt because of the cero firing, it was because he fell through a black portal. (Perseus Exit)
Romano had shot an arrow right below Perseus. With Virgo's ability he could create portals to the Soul Society and Hueco Mundo. The black ones led to the SS, and the white ones led to Hueco Mundo.
Romano had been largely silent during the battle, as Perseus had done most of the fighting. But he spoke. He had a slight Italian accent "It seems that the moon is breaking apart" He then shot an arrow next to the arrancar, a white portal opening up, showing an image of hueco mundo. "That portal should take up back to somewhere in Hueco Mundo. I assume you should be safer there. I know you have no real reason to trust me, but I assure you I'm telling the truth."
After that He shot a black arrow at his feet, opening a portal for him self. He sank into it as he said "Arrivederci." before the portal closed behind him. (Romano exit)
