Aoi Hikaru ga Chikyuu ni Ita Koro......

Our protagonist, Inoue Konoha is still being led around by his senpai, the Literature Club's President, self-acclaimed "Literature Girl" who loves stories so much that she can eat them, Amano Touko. One day, someone put a bunch of paper scraps that have words like "Hate", "Ghost is" and a bunch of puzzling numbers on them in the Literature Club's "Love Consultation Post Box". Calling the act "picking a fight with the Literature Club", Touko once again gets Konoha involved in her investigation; but, when they find the culprit, the girl turned toward them, smiles, and says "I'm already dead." The 2nd arc of the popular bitter & sweet school mystery series.

The "mysterious school comedy" centers on the unusual members of a high school literary club. Tooko Amano, a high school senior who calls herself the "literary girl" as the club president, is actually a supernatural creature (youkai) that devours stories, she tears pages from books to munch on them. Her club subordinate is Konoha Inoue, a second-year high school boy who writes stories every day for Amano to eat. He once wrote an award-winning novel, but he wrote it under the pen name Miu Inoue so readers thought the author was a mysterious 14-year-old bishoujo novelist. The stress from the novel's fame and its movie and television drama plans turned Inoue in an introverted recluse. Adapted from the "Bungaku Shoujo" series of light novels

The story starts with the death of Hikaru Mikado. That guy was a natural charmer, a “harem king”, but had no real male friends. After he died, he became a ghost, a soul, but Koremitsu Akagi can see him. Koremitsu though, isn’t really like Hikaru. His red hair and his evil-looking eyes make him look as a delinquent, even though he is very kind inside. Hikaru asks him a favour: he wants to fulfill a promise, which he couldn't fulfill anymore. The promise was to give his girlfriend and fiancée, Aoi Saotome, 7 gifts for her seventeenth birthday. Koremitsu accepts, and has to work hard to help fulfill Hikaru’s promise with Aoi.
