Modern/2004/Tragedy/High School Titles

Koushiro has lost his way in life. His steady girlfriend broke up with him because their relationship was not going anywhere and she tell him that she has fallen out of love with him, and his job at a dating service was not bringing him any measure of happiness. During his commute home, he sees a high school student on the train, and feels a strange spark of connection. The next day they happen to meet again, he approaches her and asks to spend some time together. In an amusement park, they spend some time and talk, where Koushiro finds himself opening up to her, shedding tears at the memories of his broken heart, and where he finds himself being comforted by her.

High School student Shinichi Kudou was a virtual Sherlock Holmes, who the Tokyo police regularly turned to for help in solving baffling cases. But then he accidentally learned too much for his own good about a murder case, and was caught by the villains. They poisoned him and left him for dead, but the "poison" had an unexpected effect--rather than killing him, it caused Shinichi to revert to the appearance of an elementary school boy! He retains his skills as a brilliant detective, however, and since that incident has managed to become adopted by his former girlfriend and her less-than-exemplary private detective father. With them he carries on his passion, and searches for clues to a possible antidote to the poison he was forced to swallow.
