Office worker Satou Konoha dies in an accident and is reborn as a character from a story she wrote as a student, "The Dark History."

To save Konoha from the monster that kidnaps her, Iana triggers her own death flag; with help from Sol, Ginoford and the others, Konoha's rescue succeeds.

As Iana grows used to life in the world she's been reincarnated into, a young man comes to visit; her childhood friend Yomi is back from studying abroad.

Yomi mistakenly believes that Sol is tyrannizing Iana. His pure love and loyalty to Iana lead him to target Sol's life. He sets up a magic trap, creating a man-eating flower that attacks Konoha. Ginoford and Sol defeat the creature, but Sol believes that he's the target of the strange events that have occurred, including this attack, and he turns to Iana with a gaze full of suspicion.
