So far, I think InuYasha is my favorite longest running series. I think it's been in its FINAL arc since December. Chapter 548 came out Wednesday, and it's slowly coming to a close. As in, they're still all inside Naraku and killing him in some unknown way. Shippou's running around being useless. Naraku's last incarnation (Byakuya) is dead, and he did some weird thing to Kagome. And apparently Sesshy's arm grew back. >_>;; For shortest running, I'd have to say Chrono Crusade. It was short, but it had a reasonable storyline and was really sad at the end. My friend and I always argue as to what really happened to Rosette and Chrono at the end. So yeah. I'm gonna go get breakfast. You can state your series. :3
DN Angel and Fruits Basket are my favourite long running series....... All the manga I have are long series, so I don't really have a favourite short series manga.
Naruto. And honestly, at this point it is fun to see how bad it is getting. Not exactly a manga, but I also love following So Common, So Cheap. There is something so addicting about it...
Naruto, I've bought every English mange book so far. It's addicting. Also Fruits Basket, I just LOVE reading about Kyo and Yuki, and stuff. <333
Longest it is a tie between Inuyasha and Fruits Basket. Shortest? Either FLCL or Wolf's Rain (2 volumes!) I randomly have Bo-bobo-bo-bo-bobo (sp? oh who cares?) somewhere, that's just 1 volume.
my favorite longest running manga is naruto.and shortest running is a tie between wolf's rain and pastel.
