Asaji Mainichi is a small-time criminal in the early chapters of Death Note, one of the many petty offenders Light Yagami eliminates while under L's watch. His death forms part of Light's scheme to appear innocent before the observing Task Force.
Mainichi has short, dark hair, a thin mustache, and a covering of stubble.
The series reveals nothing of Mainichi beyond his standing as a minor lawbreaker, the kind of small offender whose crime rates a passing mention on the evening news.
Worried that L still has him under suspicion, Light Yagami devises a way to keep killing without exposing himself. He sits before the hidden cameras in his room watching television and quietly ends the lives of lesser criminals as their names and faces appear on screen, all the while memorizing major offenders to deal with later, away from the watchers. The upshot is that bodies keep dropping no matter whether he appears to be watching the screen. Mainichi is one of the minor criminals whose name Light enters into the Death Note during this stretch.

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....
