Son Of Another Kind

So we all usually see stories where Percy Jackson is either betrayed, abandoned or cheated on; stuff that makes him hate certain people and leave camp behind after maybe having almost died.

My proposal is that: during the house of hades, he alone fell into Tartarus. What happened after~? A certain black cat with two tails felt his panic and hurt. It exited a big cozy blue-painted bedroom and entered a throne room with a total of 10 chairs. However, one is broken and it's remains flew over the throne in the middle. In the big chair sat a man with white hair who was as tall as the gods of Olymp themselves. He looked tired and melanolic but wise. The person saw the cat and asked what was wrong; "My Lord, I felt him. I felt a connection to your son! It's weak and I fear if nothing is done he may lose his life yet again!" spoke the cat.

"WHAT!" yelled the god like ruler.
"SONS! To me, now!" one after another they appeated: a beam of light, a magic circle, one followed by wisps entered through the door, one appeared in fire, another in water, the next crashed in from the balcony on a swarm of flying mouses wearing punk clothes, another poof'd up next to the one who appeared in a magic circle with a spike on his head; the last, appeared in a puff of brow with holes the size termite bites in his clothes.

"You called father?" asked the one who appeared first dressed in white military clothes. "Yes." he looked at one of his sons. "Azazel, your kin felt a connection. It was weak and I fear your brother might just get ripped out of our grasp again. I doubt I need to speak any further.". It was quiet.
"Kuro; where had you felt the link from?" quickly asked the one with the wisps in a grave tone .

"It was very dark, there was no sun or moon. Beings that were not demons or humans dwelled there. It was incredibly loud from all the monsters and screams there. There was... however a presence that felt like lord Satan, if a bit weaker." Satan hummed getting an idea of what and who they were dealing with but it was no one important.
"I believe I know where. I'll sent you, Samael, Azazel and Iblis over. Find your brother, I'll have a little talk about how a junior of mine has been treating my son." he opened a portal giving his sons a name to the place. They recognized it, well.. The older ones did. With that they rescued Percy Jackson; the reincarnation of their youngest brother, the 9th demon king. The ruler of shadows, their crown prince which was the last son of Satan: Rin Okumura.

Never mess with an God as old as the primordials and a demons family! They will soon get a rough awakening when monsters cover in fear of the superior race as they make way for their ⬆️ prince.

"Rin, Egyn, wait up!" spoke someone flying after the other two who were ahead of him.
"Leave it Azazel, you know that he is pissed. He will do whatever he wants. What he did to Samael back then is/was a prime example" said the lighter blue one diving after the deep blue one. Below them a fight between monsters (a barrage of Hell hounds as well as multiple furies and some Minotaur's) was waging against a group of mortals with unique weapons and powers. Their presence didn't go unnoticed it couldn't go unnoticed.

{they are a kind of dragon, their united form is a symbol of the Gehennian royal family. They do have their own unique forms tho}

They landed next to each other as the monsters who spotted them made way and bowed making the battlefield go quiet. "My, I always knew I make others gape at me but to have demigods do so just makes me annoyed... Especially... If they have replaced me." offendedly spoke Percy *coughRincough* to himself.
