Premise

An office worker named Konoha Satou is killed by a truck and reincarnated in a world based on The Dark History, a self-insert fantasy novel which she wrote during her teenage years. Having written the main character as her Mary Sue self insert when young, in a twist, adult Konoha is instead reincarnated as the main villain of the story: the main character's evil sister, Iana Magnolia. Knowing that in the original story, she wrote Iana being killed after trying to murder her elder sister, she becomes desperate to avoid dying, doing everything in her power to ensure the safety of her sister. Having to convince others that she's not evil anymore, having to face her old teenage writings that she finds cringeworthy now, and making friends with her own characters along the way, Iana needs to remember the plot details of her own once forgotten self-fiction, in order to save her sister, friends, and herself from the many events they face throughout their adventures.

Characters

• Iana Magnolia (イアナ・マグノリア) / Konoha Satou (佐藤コノハ)
• A Japanese office worker who was killed by a passing truck and reborn in a world based on her childhood novel, but as the wicked sister of the story's main character. In the original plot, she was meant to be executed. Not wanting to die a second time, she becomes determined to protect both herself and Konoha using her knowledge of the plot, but her actions begin to change the story. Even so, the story still attempts to undo her changes.
• Konoha Magnolia (コノハ・マグノリア)
• Iana's elder sister, who could use magical abilities and is named after Iana's original incarnation. She was targeted for assassination by her sister in the original storyline. In the altered storyline, she doesn't discover her powers, which leaves her unable to fight, and Iana wishes to protect her rather than kill her. She loves her sister despite knowing of her misdeeds.
• Sol Nemophila (ソル・ネモフィラ)
• A butler who was meant to kill Iana in the previous storyline. In the alternate storyline, he instead falls in love with her and is desperate to keep her safe. He and Yomi are bitter rivals.

• Cheneau Clematis (シャノウ・クレマチス)
• The Vice Captain of the Hydrangea Security Force. He hates Iana due to her villainous nature, having also arrested her in the past. He still holds his grudge despite her personality change, mostly because he thinks Iana is responsible for the disappearance of his sister.

It is later revealed that he is a member of a dark organization called Schwartz Le Chevalier, who seeks to awaken Konoha’s powers for their own gain.
