Ito Shiroba is a motorcycle traffic officer whose routine stop of a speeding driver makes him an unwitting casualty in the hunt for Kira. His abrupt death hands L a crucial clue about how the killer is able to strike.
Shiroba is presented as a uniformed traffic officer who patrols on a police motorcycle.
What little the story shows of him is professional diligence. He pulls over a reckless driver and, when the man bolts mid-stop, immediately gives chase rather than letting the violation slide.
Shiroba pulls over Kyosuke Higuchi, who is racing toward Sakura TV to stop Matsuda from exposing him as Kira. While pretending to search for his license, Higuchi uses his Shinigami Eyes to read the officer's name and enters it in the Death Note, then tears away once more. Shiroba sets off after him and is killed in the crash that follows, slamming into a truck. The unexplained death leads L to deduce that Higuchi can kill merely by seeing a face, prompting him to tighten the plan for the suspect's capture. Shiroba fills the same role in the 2015 television drama, where he carries a different name and his lifespan is shown. His written name is even a pun, reading as police bike in a nod to his profession.

The transformation everyone knows, the follow-up question nobody would touch. Why we made a smooth R&B track about the golden glow Dragon Ball never talks about....

Five Bleach female characters, ranked and settled. Yoruichi sits at number five, the spot nobody expects, and our number one is an Arrancar with a soft heart....
