Viewfinder is all I can think off xD

Forever lurking...

Ai no Kusabi has action and sci-fi.

wild adapter- sounds perfect for what you want.
From Eroica With Love- same again, but how do I put this? the main character I would say is kind of 'womanish' in a way (perhaps 'flamboyantly gay' would be a best decription), but without the extreme girlishness you usually see in so many main characters.

U don't know me
Doushitemo furetakunaii (he is kind of shy, but more like a real troubled man) You have to read Yoneda Kou, especially if you liked Suzuki Tsuta
Prince Charming
Gerard & Jacques (Yoshinaga Fumi has really good stories, though the art seems ugly it is really charming when you get used to it)
Sangen Tonari no Tooi Hito
Renai Junkie
CUT
Arashi no ato
Seven days
Negai Kanae Tamae
Bokutachi wa Asu ni Mukatte Ikiru no da
Bond(z)
Konna Otoko wa Aisareru (honjou rie is a good one)
Ikenai Otoko
Memory of the future (flamboyant gay)
Darenimo Aisarenai
Yume wo Miru Hima mo Nai
Ai no Gebokutachi
Dash!
Fake
Maiden Rose
Love me hard
Mukizu ja Irarenee, Buddy system (or anything from Sadahiro Mika)
Ikoku Irokoi Romantan (Yamane Ayano has some good options)
50 x 50
Nanahikari
Kawaii Akuma (this is a weird one)
Boku no Shiru Anata no Hanashi
Koi suru boukun

My Reviews

Alright, I think somebody may have already recommended some of Sakuragi Yaya's stuff, but I'm gonna put my two cents in anyway and recommend her story Plus 20 cm no Kyori. It's one of my personal favorites.

Mind eraser, no chaser
