Business is slow for the Ootsuji Detective Agency. Soutarou and his juvenile sidekick Saki will take any job that comes along, even one that sounds like a lot more risk than it’s worth. It’s festival season in the city but away from the public eye, a wave of mysterious disappearances has occurred. A newspaperman hires Soutarou to investigate, suggesting that answers might lie somewhere in the Dark, the notorious, anarchic maze that is the city’s physical, social, and moral underground. Soutarou subcontracts the gig to Saki, but soon enough regrets it when the kid also goes missing. Now Soutarou is obligated to venture into the Dark himself, and confront its dubious subterranean denizens, including the malicious Laughing Masks gang and the renegade police squad piloting the fearsome Demon 463 armored train!

You don't have to shine to have youth. First-year high school student Uta Komaki loves to sing, but she's extremely shy, timid, and a bit of a coward. She wants to join the light music club for her high school debut, but she's too intimidated by the dazzling presence of the members to submit her application. In her moment of despair, she receives an invitation to join the a cappella club from the president, Airi Kojou... The a cappella club is filled with unique individuals—some might say they're a bit odd. Even if they're not flashy or popular, there's a special kind of youth that connects through their voices, creating something truly unique. (Source: Pony Canyon)

The special of the day is Variable Geo-a brutal battle between waitresses who serve up generous portions of energy blasts and vicious side orders of murderous martial artistry. For buffed beauties who make below-minimum wages, VG is the perfect way to make some fast cash. The victorious walk away with millions, and the defeated lose everything (namely, all their clothes). But this high-stakes sport has dark forces and dubious practices behind the fun and games. Lethal injections make steroids seem like vitamins. Instead of team prayer, there's demonic possession. Athletic sponsors are malevolent corporations with a more frightening agenda than increased market share. It's all just part of the game. (Source: AniDB)
