What Makes Gremory Highschool DxD Fans Debate The Strongest Character?

Although the Supreme returns in order to pass his days peacefully, he was belittled by everyone. On his wedding day, with a wave of his arm, he summoned the Nine Great Gods of War to him, who addressed him as their master…

Tasoshi Saya, the Supreme God of Zeronity. He was the strongest god to ever live. A mountain of strength that could never be crossed. On the day of his match against his opponent, the Breakers—he was suddenly transported into another world. A world filled with swords and magic. Power? Glory? All that was lost as he entered into the new world. Yet, despite his helplessness, the 'Supreme' God of Zeronity was excited.

"Agh, why are you so cruel to me? Why do you, these mighty beings, want to take them away from me? What have they done wrong? I, Xiao Chen, cannot accept any of this—I refuse! Whoever you are—god, demon, or even if you are Heaven itself—I, Xiao Chen, will forge my own path. I will destroy all of you who take everything from me!" The roar of anger from deep within Xiao Chen’s heart revealed his hatred for Heaven’s path and Heaven’s will; walking a different path from the rest, Xiao Chen strove once again to protect the people he loved. He strives not to lose a single person currently by his side; even if he must fight against Heaven itself, defy fate, or even confront all the supreme gods, Xiao Chen will still walk his own path. To avenge himself against Heaven’s will, to destroy the path of Heaven, and to become the supreme being controlled by no one. The path of defying heaven will be extremely arduous, far more so than the path to immortality and becoming a god. For those who constantly defy the will of heaven never end well. Xiao Chen’s journey will continue. Will Xiao Chen become a being uncontrolled by anything? Or will Xiao Chen instead become a being controlled by the will of heaven, just like the others?

He died killing the Demon King. He woke up sixty years too early. Now the monster is a young man. And he is running out of reasons to stay away. --- Lysan Dusk was the hero who saved humanity. He killed the Demon King, ended the war, and delivered the world from suffering, and his reward was betrayal. He wakes up in a young student's body in a dormitory room of a magical academy, and the calender shows that the date sixty years before he was born. The world outside hasn't broken yet. The war hasn't happened. Lysan's plan is to keep it that way by staying completely out of it. Fail his combat exams, spend whatever borrowed time he has left, living a quiet life, where nothing requires him to be a hero. The man who will become the Demon King, the most feared monster in history is still young and beautiful, with pale grey eyes that find Lysan across every crowded room like he is the only person worth seeing. Lysan knows what those eyes will become. He has looked into them across battlefields, spent a lifetime seeing them in nightmares. He never expected it to feel like this up close. Roman is everything Lysan was warned about — magnetic, dangerous, impossible to ignore. Everyone except Lysan, refuses to be charmed, refuses to feel anything at all. But now, he is failing spectacularly at them because Roman keeps finding him. Keeps watching him and making Lysan's carefully rebuilt walls feel like paper. Lysan knows the ending. But for the first time in two lifetimes, he is wondering if the ending can change. If the monster can be loved instead of killed. If staying is braver than running.
