Sirzechs Gremory, now the new generation Demon King and holding the title of Lucifer, along with his nobles sailed across the Western Eternal Ocean to reach the Nix River. The river into Underworld. On their journey, they encountered Ophis, the Infinite Dragon. Ophis formed the student organization called the Khaos Bridge. She enlisted Kaguya Otsutsuki as a core member.
She met Ophis when she escaped the Seal of the Moon.
Kaguya gained a second life after Yu Ha Bah gained the power of the Soul King and united the Three Worlds.
Yu Ha Bah united the powers of the three factions of the afterlife: Angels, Fallen Angels, and Demons.
They both entered Dragon God College as teachers. Students from the Wizard Academy in Andalusia also came to Dragon God College, such as Zeref Dragnell, Suzuki Satoru, and Nico Robin. They were new students from the Hero Academy, Yokai Academy, and Kuoh Academy.
After the Student Orientation Program concluded, they entered Dragon God College. Not only Dragons and Monsters study here, but also human students. Only a few human students enter this school. Special human students are able to study at this university.
Supernatural powers are the foundation for entering the university. The greater a person's fear of a particular individual, the greater their chances of entering the university.
For example, Zeref Dragnel is a dark wizard who possesses the power of the God of Life.
He used forbidden magic to revive his brother, Natsu Dragnel.
Ophis, a student renowned for her supernatural powers, has formed a student organization called the Khaos Brigade. The purpose of this organization is to fight for the rights of supernatural students at Dragon God High School and protect them from all forms of discrimination. Ophis is the leader of this organization and strives to recruit strong and determined members to join the Khaos Brigade.
One of the people Ophis hopes will become a key member of the Khaos Brigade is Kaguya Ōtsutsuki. Kaguya is a student with immense power and is respected by many at Dragon God High School. She possesses the ability to control the elements of nature and possesses powers that can alter the universe.
One day, Ophis encounters Kaguya as she emerges from the Moon Seal, where Kaguya resides. Kaguya is both surprised and delighted to see Ophis, as she is one of the students she respects. Ophis then invites Kaguya to join the Khaos Brigade, believing that with Kaguya's power, they can become an unstoppable force at Dragon God Academy.
Kaguya is surprised but honored to be so highly regarded by Ophis. She agrees to join the Khaos Brigade, and together they begin to plan a course of action to fight for the rights of the supernatural students at their school.
Meanwhile, Yu Ha Bah, a student who possesses the power of the Soul King and has united the Three Worlds, grows jealous of Ophis and Kaguya's success. He believes his power surpasses theirs and begins to plot a way to seize power at Dragon God Academy.
Yu Ha Bah collaborates with the Afterlife faction, namely the Angels, Fallen Angels, and Devils, to create a sinister plan that threatens the security of Dragon God Academy. They planned to overthrow the Khaos Brigade and seize control of all the supernatural powers within the school.
However, Ophis, Kaguya, and the other members of the Khaos Brigade did not remain idle. They began strategizing and fighting the evil forces that threatened to destroy Dragon God High School. They teamed up with human students who also possessed supernatural powers to fight Yu Ha Bah and the Afterlife faction.
In the fierce battle between the Khaos Brigade and Yu Ha Bah, Ophis and Kaguya used their incredible powers to defeat their enemies. They proved that unity and collective strength were key to defeating the evil forces threatening their school.
Finally, after a long and grueling battle, the Khaos Brigade defeated Yu Ha Bah and the Afterlife faction. They proved that with strong determination and unwavering unity, they could overcome any challenge.
Ophis, Kaguya, and the other members of the Khaos Brigade finally celebrated their success and prepared to face the new challenges ahead. They realized that the fight to protect the rights of supernatural students would never end, but they were ready to face it with courage and strength.
