So after stumbling upon the Devoted Followers tag and adding a few series I knew of, I decided I'd like to read some more.

I'm feeling pretty leinent, so you all don't have to read one of my long, detailed, and painfully specific requests. Just keep away from yaoi, yuri, shounen/shoujo ai and hentai please. Also, I'm not looking for a bishounen fanclub type of devotion and I'm not really too keen on harems either unless it extends beyond romance.

Some of the best examples from the list are probably Katekyo Hitman Reborn!, Noblesse, Maou: Juvenile Remix and Rappi Rangai (even though it's a harem, there's some feudal loyalties and stuff).

Thanks in advance

Thanks, I've aready read Dance in the Vampire Bund but I might check out Gunslinger Girl, since I've been seeing it get recc'd all over the place.

Anyone else have something?

20 Seiki Shounen + 21 Seiki Shounen
