Mystery Anime (976)

Whether its solving a crime or finding an explanation for a puzzling circumstance, the main cast willingly or reluctantly become investigators who must work to answer the who, what, why, and/or how of the current dilemma. The narrative of mystery stories is always on collecting evidence, identifying suspects, and theorizing possible scenarios for the unexplainable, before finally capturing the perpetrator or resolving the current situation.

Almost always, the audience has the same information as the main characters and anticipation is directed towards discovering the explanation, not what will transpire after the answer is found. Contrast with Suspense or Horror where often the audience has more information than the cast, which heightens the tension or fear of what will happen next.

Lee Sori, a polite and righteous girl, attends a middle school plagued with bullying. Enraged by the tragic effects it has had on her friend Kim Julie, she decides to take a stand against the bullying. Unfortunately, this only leads the bullies to switch their target to Sori. Believing a new environment would rid her of the hopeless situation, Sori returns to the city she used to live in and transfers schools. However, the traumatizing experiences that constantly haunt Sori's memory cause her to alienate herself from everyone else. Just as the grim reality of Sori's circumstances begin to set in, she discovers a mysterious letter taped under her desk. While the contents of the letter intrigue her, they only lead her to another letter. Now following a seemingly endless trail of messages, Sori is on a scavenger hunt to find the true purpose of these letters and the anonymous person behind it all. [Written by MAL Rewrite]

Arikitari Heroes is an original song featuring Hatsune Miku, GUMI, Kagamine Rin, and MAYU. It is the fifth song in the Bookmark of Demise Project. It can be interpreted as an answer song to the four earlier songs in the project, because it contains events from those songs. Events include A-ya playing hide and seek alone, C-ta's murder of A-ya, D-ne's imitation of B-ko, and A-ya and C-ta's childhood memories. After getting a couple words from each participent in the Demise Game, it opens upon the group play Kokkuri-san to summon the Bookmark of Demise. (Source: Vocaloid Wiki)

A movie version of Sushi Police that includes all episodes from the TV series. Honda, Kawasaki, and Suzuki all comprise the elite ninth unit of the Sushi Police—a task force with the sole objective of sniffing out restaurants serving illicit or non-traditional sushi and eradicating them, no matter how insignificant their offense may be. The Sushi Police travel freely around the world in pursuit of these vile criminals day or night, with their strong sense of justice and the World Food-Culture Conservation Organization backing them. No offenders of Japan's traditional cuisine can escape their wrath! During one of their purification missions, the Sushi Police encounter Sara—a hot, young, television reporter out to expose them and the World Food-Culture Conservation Organization for corruption. They interrogate her, but her wiles, skills, and charms allow her to easily escape from their grasp, setting off a chain of events that will lead to the true purpose of the Sushi Police being revealed.
