Shinigami-sama ni Saigo no Onegai wo

A relatively new manga which started in 2009. Shizuka Aida is a young teenager who is three days away from being executed for cruelly murdering his family, when a Shinigami comes to visit him. Turns out the Shinigami who appeared before him happens to be his little sister, Hibiki, and she has come to ensure that she takes his soul to hell, personally. She has another job on this trip as well, and that is to grant the final wish of a girl with heart disease, and she drags her condemned brother along with her.

Soon, it becomes apparent that people are not as simple as they may seem at first glance, and even Shizuka's guilt is uncertain. Hibiki and Shizuka promise to search together for the truth about their family's death, and they won't let life, death, or trouble in the afterlife get in their way!

This series provides examples of:

 * Ax Crazy -- Asami Arisawa, who is the first client we get to see. She ended up killing seven people with a cleaver before Hibiki cancelled her wish, because she wanted to feel the thrill of the hunt.
 * Beware the Nice Ones -- Don't mess with Boy A Shizuka and get him mad. Don't.
 * Big Brother Complex --
 * Break the Cutie -- Happened with Hibiki. Initially somewhat averted by the fact that Shizuka was not yet dead, but later played straight when
 * Cute and Psycho -- Again, Asami Arisawa. See Ax Crazy above.
 * Dead Little Sister -- Hibiki, who at the very beginning is certain Shizuka was the one who murdered their family. Later evidence suggests that even he himself is unsure if he did commit the murder.
 * Distinguishing Mark -- Shinigami are identified from normal humans by a strange symbol that is found just under their right eye.
 * Eyes Always Shut -- Shizuka rarely ever opens his eyes, and most of the panels he's appeared in shows him with both his eyes shut. He does occasionally opened just one eye, but the overall air about him when he has both eyes closed is that he is a rather spacy individual. However, he has shown analytical skill that betrays his nonchalant appearance. When he has both eyes open though, beware.
 * Groin Attack -- Satsuki gives one to Shizuka in chapter three.
 * Informed Attractiveness -- Hibiki has been described as having a beautiful figure by some characters, but with the art style used in this manga, she's not really a stand-out.
 * Meaningful Name -- Hibiki means "sound", and Shizuka means "silence". It spills into their personalities as well, as Hibiki tends to be the rash, reckless one who charges in head-on into problems, while Shizuka is the cool, calm and meticulous one who plans out everything carefully, even having back-up schemes should an earlier plan fail.
 * Shinigami -- Hibiki becomes one of them, after her death.
 * A few others have also appeared, namely Luka, Ume, Yoshino and Satsuki.
 * Sibling Yin Yang -- Shizuka and Hibiki couldn't be more different.
 * Token Mini Moe -- Satsuki, one of the higher-ranking Shinigami.
 * Tsundere -- Hibiki, towards her brother. Lampshaded in the omake at the beginning of chapter two.
 * White Haired Pretty Boy --
 * Zettai Ryouiki -- Hibiki has this when in Shinigami uniform.
 * Zettai Ryouiki -- Hibiki has this when in Shinigami uniform.
