She heard Omaeda screaming in the distance, but she knew he was running. The screams were coming from different directions, sometimes nearer, sometimes further. That raspy voice hissed once more "Respira". Omaeda continued screaming, which was a good sign. Shows he has not rotted to death yet. I… I just need a few more minutes.
She gritted her teeth in frustration. That which normally only took a few seconds when she had the use of two hands now required several minutes. She could not be entirely sure of the knots she had tied around herself as well, whether they would be strong enough to hold. She was thankful, however, that she still had the use of her legs and shunpo. That made the multiple rounds around the building easier.
A misfired kido blast sounded somewhere to her left. The screams started once more, and Omaeda's huffing and puffing became louder.
She recalled a rumour she had about the 11th Squad – "Ikakku Madarame has attained bankai and Yumichika Ayasegawa has a kido-based shikai!" – or so it went. She frowned. Madarame would not have lost if he had released his bankai against Chow Neng Poww. Then again, knowing the 11th Squad's reputation, he would probably be expelled from his squad and forced to take up a Captaincy if he was ever found out.
She sighed, somewhat bemused that she had something in common with Ikakku and Yumichika. I wish I did not have to resort to this. But pride is no matter now. Life and death are at stake.
She tugged firmly at the remaining end of the ginjohan, hoping the knot would be secure. In the distance, someone yelled "Taichouuu!!!!! Help me!!!!" In the distance.
She ignored the screams and focused on her enemy instead. Barragan, you may be the god of death in that you kill and bring people to death's door. But I am Shinigami. Shinigami guide people beyond death's door. I exist because you do your work, yet I and my works do not serve you. Your works serve me.
Soifon stepped onto the roof and held her zanpakuto in front of her with her remaining arm.
