When all looked up there saw many people levitating high up. They wore a black and white kimono with sandals on their feet. And swords on some of their hands while some had swords on their backs.
For those who have watched John's works. They knew who these people were. They were the famous death gods.
The Shinigamis.
Yes, the bleach series was what John had just summoned. He just spent an entire 50 billion fan value. Almost all that he had to summon this entire world. From the very beginning he wanted to control this dimension. And the most efficient way to control the dimension was by using a huge force and an overpowered one at that.
And bleach was the perfect series for that. And in addition he bought one of John's favourite characters.
Genryūsai Shigekuni Yamamoto.
John really loved his character. John in his series didn't show beyond the arc of Aizen and thus Yamamoto was still alive as opposed to being killed during the Thousand Year Blood war arc (sorry for the spoilers). This had both pros and cons.
Pro was that he didn't need to spend fan values for Yamamoto. But the biggest con was Yhwach. If John needed to bring him and his full 'family' he needed to spend more on fan values, which would probably be in the tens of billions.
And John liked to keep it that way. He had Hueco Mundo which he could easily attach anywhere he liked and have fun with it. But Yhwach and his whole 'team' would be the personal army of the Avengers.
During the war against Black Winter they had very less personnel in total and John had decided long ago that he would change it. And since Seireitei would be in a totally different dimension after they defeat Mephisto it didn't matter where the Quincies lived.
So John could use them always and after accumulating more fan values he would bring them here. Since Knull would awaken God knows when, he needed to have some contingencies. And who was better to face against Knull then 'The Almighty'.
Though he could face Knull alone too, Knull had a huge army that could bring down universes to its knees so he needed more people in this regard. The more the better.
The people who were levitating on the top were the 12 division captains and Yamamoto (before the last arc). And of course the protagonist of the story.
Kurosaki Ichigo.
All the demons stopped on the tracks after that hit of Ichigo. They couldn't make head or tail of how new people had appeared again. Mephisto had total control of this dimension so how could he allow new people to arrive and powerful one at that.
All the demons could feel a pressure emitting from each one of them and it made them feel suffocated and danger. It was like the soul was being crushed by something.
Mephisto too was taken aback by the sudden emergence of new people. He too could feel that these people weren't simple, especially the old man who was holding a cane. He felt like this man was more of a monster than he was.
And the main thing that scared him a lot was that these people weren't exactly alive. It felt like they were dead but he also felt the breath of living. It was a contradictory feeling which he felt hard to describe.
Lucifer, who saw Mephisto was distracted by the people, threw a kick at his face with full force. This kick threw him away a few hundreds of kilometres.
"So this will be our new home. Not bad. Homecoming starts with bloodshed. I like it." came the rough voice of Zaraki Kenpachi. His spiky hair and his eyepatch.
John made sure that these people had their new powers which they got during the blood war. Like Ichigo's new shikai. Kenpachi's huge new shikai which looked less like a sword more like a butcher knife made to kill huge demons.
"Can you all come down and help? Instead of being all high and almighty?" John shouted.
"Ah sorry sorry... Our apologies... We came a little late..." Kyoraku said in a very feminine tone as all appeared near them in a flash. everybody had come down except for Yamamoto who was still in the air and was looking in the direction of Mephisto.
"So these were your help? I thought there would be more?" Constantine said. he could recognize each and everyone of them. Thanks to John's works he knew them but still felt they lacked people in fighting against these many demons.
"Who said we are the only ones?" Unohana said in her classic scary look. This scared the shit out of all the people present. Including Strange who was lost in his own world when he got to see the new people.
