Takuo Shibuimaru

Shibuimaru decks himself out in sunglasses, an assortment of rings, a gold chain, and a jacket.

Shibuimaru runs with a pack of bikers and behaves like a brute, cornering and menacing a woman in the street. The films sharpen his cruelty further: there he is a man who walked free after killing five children, openly gloating about beating the charge, mocking the grief of his victims' families, and brandishing a knife to taunt anyone who looks his way.

While he is busy hounding the woman, Light overhears his name and watches the scene unfold, then commits every spelling of it to the notebook under one condition, that a traffic collision take his life. Moments later a truck plows into Shibuimaru's motorcycle and kills him. The act gnaws at Light afterward, since the biker, for all his menace, was no convicted criminal.

The 2006 film reworks the encounter. There Light pulls Shibuimaru's name from a police database he has hacked, finds him in a lounge crowing about an acquittal for the murder of five children, and is threatened at knifepoint for his trouble. Later, spotting the criminal staring at him across a railway crossing, Light commits the name to the Death Note, and a passing train masks Shibuimaru's collapse from a heart attack. In certain runs of the stage musical he is recast as the killer of Misa Amane's parents, again dying as Light's second victim after walking free for lack of evidence.
