Touko is a senpai one year older to Konoha and the president of the literature club. She likes literature to the extent that she happens to eat what she reads. It was her who forced Konoha to be in the literature club so that she could "look after him" as a reason so that he would not tell others that he had seen Touko eating the pages of a novel.
Spoiler!She also likes Konoha, but chose to leave him.
Her past was revealed in "Romancie" books. Her father was the editor of the publisher that was in charge of publishing Miu Inoue's only book. This is why Touko knew what the end was written his book before. She's his FIRST fan that has waiting for Konoha to write second book and knew that Miu Inoue = Konoka.
Her parents passed away in a car accident. Her mother was the one who had been written for her "food" , but after their death, no one could write them until she found Konoha. Her aunt, Ryuuto's mother and the author who was one of the judges who were responsible for giving Konoha award, didn't like her much like her mother because of major story in Romancie books.
