God succession system

It was the day after meeting with the higher ups of the factions, and Alex was ready to go after Hades. He already decided that it'll just be him and his peerage, meaning him Kuroka and Rias, neither had any objection. After meeting up with Kuroka once more they followed her lead into Hades's realm.

***

Hades was in his palace trying to get the damage caused by Sirzechs fixed. He had heard of the Maou's alternate form and was anxious to see it, but didn't realize that it would cause such damage to his palace at the same time. He was annoyed that nothing worked this time, he didn't get Ophis, and those damn so called heroes couldn't even kill those heavenly dragons. As he was thinking this he suddenly felt the ground shudder.

"What was that?" He asked a subordinate. They shook their skeletal head and didn't answer him. Hades took up his scythe and went to see what it was, when his doors blasted open. Hades didn't even flinch as his palace was invaded, and watched as one of those damn dragons walked right in as if he owned the place, flanked by two women. One of women Hades recognized when she helped invade his territory the other day, and he glared with his eyeless sockets and asked,

"To what do I owe the displeasure heavenly dragon?" Alex sneered at him and went super Saiyan while also summoning his gauntlet to start the boosts.

"I'm here to remove a tumor." Hades seemed to laugh in response and said,

"Are you aware of the consequences if I was removed? Though I doubt you'd be able to do so. But I was just thinking about how annoyed I was you didn't kick the bucket before, so I'll just say it was self defense when those annoying crows and bats ask why I killed you." Alex smiled and at that time he got to his third boost.

At that word Alex's aura exploded and the cracks Sirzechs formed grew as the room was flooded with his power. He had checked with Ddraig before hand, and with all his extra training he could now take three boosts, and last about twenty seconds before his body started breaking down. His boosted gear also won't go into a cool down until he got to five boosts, due to it modifying itself during the last cool down.

When Hades felt the power coming from Alex all his c.o.c.kiness disappeared, and for the first time in his many millennium of existing, felt fear. He readied his scythe and when Alex walked towards him swung it at him expecting it go through him and take his life force. Instead Alex raised his arm and a metallic clang rang throughout the room.

CLANG!!!!

He couldn't believe it, his scythe was supposed to be unblock able. He looked to see if there were any reinforcements, but saw that the two girls were holding them all off at the entrance to the room. At that moment Alex disappeared, and Hades felt some kind of pressure in the middle of his skeletal body, before he was blown back and slammed into the wall behind him. His bones cracked and shattered, and shards went flying everywhere. He then felt the same thing on both of his arms and legs as they were all destroyed.

"Now then, how about this?" Hades heard Alex talking above him, and looked up to see him holding a jewel before he placed his gauntleted hand on his body while holding the jewel in his right. Hades then felt his power draining away as Alex took his divinity. As the last of it drained away Alex dispelled the boosted strength he had before running out of time, and called out,

"Kuroka, your turn." The cat girl then ran over with a smile, as she summoned her kasha wheel, and Alex produced another of his boosted gear jewels. He then turned to the girl,

"Are you sure you can do it?" She laughed and said,

"If I couldn't then I would be a disappointment wouldn't I, nyan?" This was the second time Hades felt fear, and he used the last of his strength to demand,

"WHAT ARE DOING TO ME?!" Alex smiled bitterly and said,

"Well even if we killed you then there's a chance you'll just resurrect later due to the influence you have over death, or possibly your allies using the holy grail. This way we can ensure you can't come back, since you wouldn't actually die." As Alex finished speaking Kuroka stepped forward and held the jewel, as she started working on sealing him into it. He then made his way to the door, to help Rias with holding back the grim reapers. The only reason she held out this long was because she was simply sitting there with extinguished star blocking the door.

After Kuroka finished sealing Hades she handed the jewel to Alex, and the three left after he stored it away. And just like that the land of the dead was deprived of its ruler.

Meanwhile Ravel had returned to the underworld, and was currently undergoing a ceremony. Her mother placed a crown on her head and the Maou Beezlebub summoned the monument, and said,

"Will the lady of Phoenix step forward." Ravel stepped up to the monument and reached out her hand while enveloping it with her aura. Once she touched the monument she became registered as a king, and Maou Beezlebub held out a box with fifteen chess pieces in it.

As she received her evil pieces she thought about what led her here. She started as her brothers bishop, but after Alex killed him she transferred to her mother and hoped to become his bishop in the future. But then she heard that he had no interest in having a peerage, and started to lose hope until she became his fiancé instead. But then the other day she learned about his plans for the future, and what he wanted to achieve.

Ravel decided that her thoughts were too small, and if she wanted to help him then she needed to step forward. She contacted her mother the same day Alex told her about Asora, and told her about her decision to become a king. She also had candidates for her peerage in mind, as her brother was kind enough to leave them behind for her. They may not be worth much in a fight compared to Rias's peerage, but she'll train them hellishly if she has to, and do everything she can to be of use to him.
