Description: The "true ending of the story" not told 10 years ago, where the protagonist turns his back on Shizuku to save Kati's life. The story takes a new turn with the appearance of a new force! Kati is involved in an incident that causes her "special gene" to awaken. The jokes of her "becoming a real magical girl!?" are short-lived, but Kati learns that if her enormous power is fully awakened, she will die. There is only one way to save her - to go along with a certain someone and betray Shizuku and the Akihabara Freedom Fighters.
