Me, Toji's Older Sister

Zenin Nanami is an ordinary jujutsu sorcerer from the Zenin family. What makes her unusual is her technique, [Chasing the Past], which is used as a secret weapon. Even more unusual is that she has a younger brother named Zenin Toji.

Her younger brother has no talent for jujutsu. Though he is clearly powerful, his family suppresses and looks down on him. For more than ten years, Zenin Nanami has struggled to survive in the Zenin family with little Toji.

During a mission, Nanami accidentally jinxes herself by saying, [Once this mission is over, we'll leave the family and live happily together, just the two of us. I've saved up enough money.] When she opens her eyes again, has she become the unlucky one forced into a substitute marriage?

After finally finding a way back from an era overrun by demons, and killing the Demon King with her friends to bring peace to the world, she returns only to be told that the Zenin family is gone?

The white-haired man in front of her, his eyes covered and looking somewhat disabled, casually picks at his ear. "It's the absolute truth. Five years ago, some guy named Zenin Toji went berserk for God knows what reason and slaughtered his way through the entire Zenin family overnight. Blood ran everywhere. There were no survivors besides a few children. I wanted to fight him, too, but unfortunately, he vanished afterward."

Zenin Nanami can barely breathe. My sweet little brother, when did you get so powerful? Are you really the same arrogant but sensible little brother I know?

She recognizes every word, but put together, they make no sense to her.

When she finally finds her younger brother, the towering young man doesn't look at all surprised to see the sister who should have been dead. He simply turns around calmly. "You're back too late. Dinner's gone cold. I'll heat it up."

Wait, little brother, your attitude is making your big sister a little uneasy!!!
