I NEED NEW ANIMES

Blood war and action: Toward the Terra
Ninjas action and samurai; Nabari no ou
ヴァンパイア action and blood: Blood(or blood+ idk)
demons swords and action: Inuyasha, Ao no Exorcist
Nice story hot guys action: Ouran Highschool hostclub, Maid sama, エンジェル Beats, Hetalia
Action Blood Hot guys: Kuroshitsuji(oh wait....they can't be gay? DARN! XD) Just kidding there are some moments but not really...

Well, I'm too lazy to think too much...but I do know the アニメ I'm currently obsessed with (Soul Eater) has blood, war (sort of), action, swords, samurai (actually, only one, though), demons, and a cool story (in my opinion). I also think a guy in it is hot, but that's not really a big part of it.

Wow.. You're way too picky. ._.' (xD ..)

Ao No Exorcist.
Has-
Demons
Action
Blood
Swords
And Rin and Yukio are smexy to me..o///o

Detective Conan/Case Closed
Has-
Blood
Action
Swords(Usually when the person is dead with a sword in him,I guess that counts.;D)

Well "Escaflowne" has swords,war,blood,and action. And in my opinion has a nice story too.

Inuyasha, but theres a perverted monk in it. I cant really think of anything else.

It has:

Demons
blood
swords
action
and a nice story

Sailor Moon, Boku No Sexual Harassment, Fruits Basket, Moonlight Lady, Mermaid Melody, イチゴ Panic, Boys Over Flowers, W Juliet, Sensitive Pornograph, Rape!Rape!Rape!, Ouran High School Host Club, Cardcaptor Sakura, and Hamataro.

Well, one of my フレンズ is obsessed with a shonen called Kenichi: The Mightiest Disciple. It has a lot of action, and according to her hot guys. But I haven't seen enough of it to tell あなた much other than the voice actors for Yuki and Kyo are in it. (In fact, I only watched it once for that! Lol, I'm such a Furuba fanatic! X3)

Sorry that's all I can give you. But if you're interested in going out and buying some マンガ to read, I can tell あなた +Anima has action, a nice story behind it, and PLENTY of hot guys. Well, Cooro's もっと見る cute, but there's still Husky and Senri... oops, now I'm babbling *blush*!

And maybe あなた can Google "shonen anime" because that sounds like your range. Although あなた did watch Furuba, my お気に入り アニメ EVER (and a shojo) (but it does have a lot of fighting, blood, and hot guys... like Kyo... and Haru... and Momitchi when he gets older in the manga... and... the 一覧 goes on XD)
And- Ah, I see you're a member of the Total Drama Island spot, hm? Well, I've been searching for something in the anime/manga world similar to TD, but haven't been able to find anything with quite as much teen angst and romance that has nothing to do with anything スーパーナチュラル または some fluffed up 愛 triangle... May I ask あなた if あなた have seen anything like that? Forgive me for babbling on like this *shame*
Good luck on your search!

THEN GO ON THE アニメ SPOT.
