We don't currently have an entry on this manga series, but I reeeally feel we should, seeing as how this manga broke records on longest-running manga and volumes sold. The problem is, I haven't heard of this manga somehow, I only knew this existed because several other Shounin Jump manga are paying tribute to Ol' Kochikame by inserting some imagery on their most recent chapter. One Piece slapped a giant M on their first page symbolizing Kochikame eyebrows, while Shokugeki no Soma, Toriko, Boku no Hero Academia both gave a character the signature eyebrows. Haikyuu gave a giant M on a character's jersey.
Anyway, it seems like this is major manga history that we should definitely document.
