Flash Marriage: CEO's Sweet Love - Chapter 689

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

It begins on the mountain.

With the glint of a knife, a flash of steel in the hands of a sworn brother. A betrayal.

Stabbed and pushed down the mountain, Zi Chen lied within the red-stained snow, left to die.

This is where it begins; he is given life by lightning,
baptized by thunder.

Those who had once betrayed him should all suffer in his cruel revenge.

Mu Mu transmigrated in the novel that had the plot like a fraud marriage with a man dressed in women’s clothing, rich man regretting and taking revenge after rebirth.

The body he had transmigrated into was none other than that of a scumbag who was a fraud man dressed in women’s clothing. He was also the one that the protagonist took revenge against.

And now, he was standing at the door of the Civil Affairs Bureau with that damn protagonist, holding the newly-released marriage certificate in his hand.

Mu Mu agitatedly raised his head. He saw the fierce and sinister expression on that damn protagonist. He was twitching the corners of his mouth, showing a grim smirk of wishing to eat his blood and flesh.

Mu Mu’s legs were weak and his eyes turned dark. He was trembling: “My good brother, why don’t we get a divorce?”
