God succession system

A few days after the party, Alex was alone wandering aimlessly around the Kuoh town park. He was doing so in an attempt to trigger the last event he knew about in the dxd world, something that would lead to a fight with a God, at least if he hadn't changed things too much. Since he had Hades sealed there hasn't been any activity like what appeared in the novel, so Alex was wondering if the situation he was expecting was even going to happen.

As he was thinking about that Alex noticed the area he was in, it was the same spot Rias "revealed" her devil identity to him when she tried to break up with him. As he recalled the memory, he suddenly felt quite a bit of hostility. Magic circles started appearing and he was immediately surrounded by roughly a hundred grim Reapers. They were high class grim reapers, and they all looked to be out for blood with their scythes ready, as they glared at him with their eyeless sockets. Alex smirked, and said,

"Only a hundred? With only that many I'm feeling insulted here." His words only further increased the hostility they showed him, but as they started charging at him three magic circles appeared around Alex. As their glow disappeared there were three beautiful women standing there, and Alex said,

"Might as well use this chance to farm XP, don't hold back." The three girls, Rias, Kuroka, and Grayfia, charged with his words. They were already aware of what Alex was trying to do, and were on standby if he needed them. While they fought, Alex was in the back using fire in a whip-like form to fight as well. He was using this chance to increase his mastery of fire control, while the girls were focusing on most of the fighting.

Rias was next to him lobbing large amounts of destruction magic at them, Grayfia had already promoted to rook, and was drawing their attacks while using her "iron defense" to repel the grim reapers scythes, even though they didn't cut the flesh, and was also using her increased strength to smash them to pieces. Kuroka on the other hand was using both her kasha wheel, and Touki infused physical attacks. She had prioritized training her Touki recently to match Koneko, since she had reached three tails while Kuroka was still only on two.

Alex was using his fire whip to immobilize some of the opponents until one of the girls finished them off, and was looking around for something. Not even ten minutes after they started fighting, the number of grim reapers was almost zero. While Kuroka finished the last of them, Alex was talking with Rias and Grayfia.

"Well I guess walking around for the last couple days worked, let's hope it triggers what I wanted to." Almost as if to answer him a girls beautiful singing voice cut through the air. Both Grayfia and Rias stopped to listen to it, and Kuroka was looking around as if to attempt to identify the source of it. The only exception was Alex, who was kneeling on the ground, as the moment he heard the song he started feeling weaker.

"Hurry, find her!" He said to the three girls, and their urgency increased with Alex's weakened state. Alex on the other hand started glowing with a golden light, and transformed into super Saiyan, surprising himself when he effectively removed most of the effects of the girls song. The song that effected him would only work on dragons, and he theorized that he would be able to fight it if he powered his Saiyan blood instead. Though it didn't seem to be a perfect solution as he could still feel a little weakened, Alex could fight it somewhat, which was more than even Ddraig could do.

Ddraig said weakly from within him, right before a purple haired girl came into view. The fact that she used a song meant to weaken him was an obvious sign of her hostility, but the fact that her eyes were glossed over said something else. As soon as she saw her, Grayfia used a hypnotism spell and sent her to sleep. Alex felt the effect of her song disappear, and removed his super Saiyan transformation. Grayfia approached the girl and said,

"It's hard to believe that this girl has the power to control dragons, but seeing how Master reacted to her earlier proves it." Kuroka nodded at her words, something that would be surprising in any other circ.u.mstances, and replied,

"Theres also those grim reapers, i thought we already taught them what'll happen if they went against us. Plus since shes so dangerous we should remove her now, Nyan." With the threatening sentence ending with the cute "Nyan", Kuroka made her stance clear regarding the girl. Rias shook her head and said,

"Alex wanted to bring her in unharmed, so there must be something more about her. At least I hope so, and it's not just the fact that she looks pretty." Alex's brow twitched at her words, but he couldn't deny them so he let it go. Instead he said something that shocked all three.

"Well, maybe if I said her name you all would understand. Her name is Ingvild Leviathan." At his words they all froze, as they contemplated the true meaning behind them. Grayfia was obviously the most effected, and asked,

"As in, Katerea leviathan?" Alex nodded while saying,

"Yep, she's a descendant of the the original leviathan, through a human partner. She the same as Vali, so much so it's almost frightening. They both are descended from both the original Maou's and humans, and they both wield Longinus class sacred gears." At his words they all reacted once more, but he cut off any questions they had and said while picking up Ingvild,

"For now let's get her back to the dorms and contact Maou Beezlebub, I don't want to stay out here in the open like this." They nodded at his words, and swiftly left.
