Now let me fast forward to the good bits. The meeting with the captains and the boy.
In case you wanted to know what happened after they saw the walls, it is thus. They saw the walls, the kid (Danny, in case you forgot) was excited, they talked to the gatekeepers, sent a few shinigami ahead to tell the captains of the meeting, walked through the city to the place where meetings are conducted and being at the beginning of said meeting.
"Who is this boy and why is he here?" Byakuya, the captain of the 6th division, asked. All the captains where present and all were staring at the boy with great intensity. The boy in turn was smiling innocently, having a sleeping Shikyo in his lap and hugging Matsumoto's arm rather tightly. She was here due to the fact that Kyoraku allowed it.
He was an odd site even to the millennia plus old shinigami captains. White hair, not to rare around here, green, glowing eyes, rare, blood caking and drying out on his head, not as rare as they wanted and monochrome clothes, common as a blade of grass in a field.
The clothes in question were not the hazmat suit he always wore when fighting crime, though no one knew that and have never seen the hazmat suit. Instead a silk, baggy, white shirt and pants were covered by an ankle length black cloak with a hood that had two raised corners near the top, resembling fox ears when up. He had bare feet and no gloves.
He had other features to boot. He was smaller than the small, white-haired captain in their midst, and skinnier as well, and looked about 14 years old.
On his arms, (they could be seen due to gravity acting up when holding Matsumoto's arm in both his arms and hugging them up to his chest) among a forest of small, fairly large, old and new scars and wounds were tattoos, but not tattoos because of the sprit energy oozing out of them, most likely restraints.
The right had two sets of black dots snaking up, from probably somewhere on his chest, stopping at his wrists and merging to create a counter clockwise spiral on the back of his hand.
His left arm however was virtually the same thing except that the dots were in a pattern of green, light blue, purple, orange, indigo, brown, yellow, red and gray and merging to make a rainbow like clockwise spiral.
Defiantly not a normal being, not shinigami or hollow or living. Not fully any of those at least.
Now the captains were smart. They knew that the tattoos were products of natural restraints of physical and spiritual power. They were on their toes from now one.
Even though most of the soul energy was restricted, they could still sense heaps of it radiating from him and the white fox in his lap. It was in a shape of a dog or a fox and was cool to their minds. The boy was so strange.
The captains stared with different emotions in them. Mostly weariness and pity, for the boy would most likely be subjected to be studied by one of their most odd captains. One pair of eyes that was staring at the boy was that said captain. His eyes were filled with sadistic curiosity and manic joy. That captain, Mayuri Kurotsuchi, looked at the boy sitting happily with the fox and the busty woman's arms in his, and thought of all the tests, agonizing and terrifying he'd heard, he'll do to the small boy.
He grinned.
