One of the great things about anime is the excellent use or interpretation of police.
In several anime series, you always have some sort of police force or enforcement agency fighting for what’s right and good against the wrong and evil. Not that many series have a strong presence of police in them.
That’s why this list is determined solely on the intense use of police alone, having the series completely based on them, or the characters representing the police itself. This means an officer or a detective.
