In the first film, Shibuimaru is a criminal who was never prosecuted for killing five children. Light finds his name in a police database after he hacks onto the NPA server, and later encounters him in a lounge, bragging about the fact that he was not prosecuted. When a man asks Shibuimaru how he felt, he brags about his acquittal and laughed at the fact that parents of his victims screamed when they discovered the acquittal. Shibuimaru finds Light looking over his shoulder and threatens him with a knife, but backs away and laughs, taunting Light by stating that no-one can prosecute him. Later on, Shibuimaru sees Light at a train crossing, gawking at him. Light, having previously killed another criminal, writes Shibuimaru's name into the Death Note, and he collapses of a heart attack as a train passes between them.
