Rin
He considered doing a little jig of his own, bowing down as she complimented him in a weird, twisted and dark way. But there was no time even for that as she appeared next to him, charging another cero in his face. Just like the first time he saw her. Although this time he was at least able to see her face. She looked better that he'd expected, although that realization didn't exactly help his situation. He was able to escape the first time around due to his Tsukiakari's special ability, this time - that wasn't the case. He was on his own.
But there was something - he still had a chance. Shoske's blade was flying towards Rin and Joker, and he felt his Zanpakuto's blade fully regenerated. Although that still didn't help his situation. "Bakudo number 8, Seki!" Rin generated an orb directly in front of his face. Not exactly hoping it would deflect the cero, not this strong of a cero and certainly not from this range. But it was a common trick used by magicians. Misdirection.
And Rin had some misdirection on his mind. Misdirection of misdirection. Since she probably saw the blade coming towards them, she'll realize he was just trying to keep her in one place long enough for it to strike. But that's where his second misdirection came into play. Both of his blades back in their place, Rin shot out one of the "wings" directly at her. Since she was aiming at him from point blank range, his blade had the same distance to cover. And since the cero was still bubbling in front of him, he figured she was still in front of him. And instantly, without knowing whether it impaled or just scraped her, Rin clenched his fist, once again disintegrating his blade into a handful of razor-like ones.
If she was impaled, they would cut her from inside out. If she was merely cut, at least his blades would have an opening to strike at.
As for the cero that shot off - well, the positive side was that due to the commotion of him shifting his blade - and body with it - and producing a Seki, his head wasn't blown off. Although the cero passed through the Seki barrier and engulfed the right side of his body, mainly the shoulder and a part of the neck.
He was sent through the air, flying for what seemed like an eternity before he managed to bring himself to a stop. Right side of his body was bleeding profusely, but at least he was still alive. For now.
