Post rebellion
Bonus:
Ashisogi Jizou
Ichigo was walking leisurely through the streets of the seireitei. Something suddenly collided into his midsection, knocking the wind out of his lungs and almost bowling him over. Stumbling back a few steps, he sent his gaze towards his assailant.
Simply put, it looked like some kind of freak experiment. A large, bald and golden baby head with blank white eyes sat on top of a limbless green body held afloat by a pair of butterfly wings sprouting from its back. The teenage substitute blinked, trying to see if he was hallucinating. The weird being was still floating in front of him, its head slightly tilted in what looked like confusion.
"What the hell?" he muttered. The thing gave an unintelligible chirrup. A second later, it zoomed over to behind his back in a panicked fashion. Before he could protest, someone else suddenly appeared before him. It was a young woman with an expressionless face and purple hair in a single braid. Nemu Kurotsuchi, Mayuri's artificial daughter. Ichigo felt the weird creature press itself against him from behind, shuddering.
"Ichigo Kurosaki," Nemu acknowledged in her usual monotone. "I'm looking for a zanpakto spirit."
"You know, you'll have to be more specific than that," he replied, although he had a sneaking suspicion on what her target actually was.
"Ashisogi Jizou," she told him almost instantly.
A figurative question mark appeared over the teen's head. "What?"
"Mayuri-sama's zanpakto spirit. It has a baby's head and butterfly wings," Nemu elaborated. "I can vaguely sense it around the vicinity, but am unable to pinpoint it."
Ichigo felt the now named Ashisogi Jizou tremble against him even more. That was more than slightly concerning, that Mayuri's zanpakto was afraid of going to his second in command and by extension him as well. The creep probably wanted to run some twisted experiment on it. Ichigo considered it a good thing that his ridiculously overflowing spiritual power was interfering with her sensory capabilities. "Well, I did see something like that just before you came," he admitted. "But it dashed off and I can't see it anymore. That's probably why you can detect the spiritual pressure but not pinpoint it."
Nemu nodded in acceptance. "That does sound likely. Very well, I shall take my leave. Sorry for troubling you." Without another word, she turned around and vanished in a burst of flash-step.
Releasing a big sigh, the orange-haired soul reaper turned around to face Ashisogi Jizou. "It's alright little guy, she's gone now," he assured. "I'd prefer if you didn't stick around with me though. I don't want your creepy master coming after me."
The zanpakto manifestation nodded in understanding and appreciation. Its mouth twitched into a small smile and it gave an affirmative chirrup. It rotated in mid-air before flying off with surprising speed.
"Well that happened," Ichigo remarked. "Did Mayuri's zanpakto always look like that, or is it because he already modified it? Actually, I don't even want to know."
