- Description from Novelupdates

The Third World War has been ended by the efforts of Kamijou Touma. With that, he vanished. With the Magic Side regrouping, the Sabbath for their followers has arrived.

In the headquarters of the Science Side, Academy City’s strongest Level 5 Esper Accelerator has washed his hands off the “Darkness.” Along with Last Order and Misaka Worst, his days pass by peacefully with no sign of GROUP.

Hamazura Shiage has formed a new ITEM with Kinuhata, Takitsubo and Mugino. Peace has come to the hands of the alumni who have “graduated” from Academy’s Dark Side at last… at least until a new evil “first year student” appears before them.

— This is a follow up to the popular Toaru Majutsu no Index light novel series, where Kamachi-Sensei has promised to deliver new premises and give a totally new flavor to the fights and plot developments

Hao Ren was born in another world and has lived for over twenty-two years being nothing but a definition of the word, average. After a high school reunion, the young man sat down on the beach shore, and mumbled to the sky, “God of Novels, you are unfair. I spent forty years of my life doing nothing but reading books and stories written by others. I worked hard to manifest this rebirth, and yet you did not bless me with anything. Why?”A voice echoed in his mind, “Host, you have the Omnipotent Husband System.”Hao Ren scoffed and scolded the system, “What is the use of having you when you are not even active? Are you shitting with me, you bastard?!”The system replied, “Host the condition for activating the system is to get married.”Hao Ren could not handle it anymore and cried out loud as he complained about this condition. He was not good-looking, and neither was he wealthy, who was going to marry him?Tired, he spent the on the beach. When he was returning home, he passed by the marriage registering center. He sighed for his fate but suddenly, a beautiful lady asked him, “Hey, do you have any identity card on you?”Hao Ren nodded in a daze, and the lady dragged him inside the office. The young man was yet to register what happened to him when an automated voice sounded, “Host, congratulations on getting married. Omnipotent Husband System is now activated.”...Years later, Hao Ren became an entity many people wished to meet. However, Hao Ren never stayed outside, to everything he had one reply, “I have to go home and cook for my wife.”Would you like to know his journey from an average to an over-achieving person standing at the apex of power and prestige?
