There are people on this board who have never experienced the pinnacle of Manly anime: Golgo 13
If K-ON is the pinnacle of feel good school moe anime(In which I love a lot), then Golgo 13 is the K-ON of manly anime.
Every episode you feel like a badass.
Isn't it just meaningless action fluff?
It's not something I particularly cared about in large doses, but Golgo has been running for longer than most active mangaka have been alive.
That's what it does best.
>running for longer than most active mangaka have been alive.
That's belong to either Kochikame or Sazae-san
