KARASUMA KYOUKO NO JIKENBO

2050, Tokyo. The sixteen year old, special gifted police detective Kyouko Karasuma works for a special devision in the Asakusa Police Department. Her rather abnormal cases involve: she's fighting against Oni, Tengu and other monsters from the Asian myths and legends. The modern art by the character designer of Speed Grapher works very good with the action-heavy story line and the overall art improves with each volume.

SAKURA TAISEN

From Tokyopop:
The year is 1921, and this is a Tokyo where monstrous steam-powered robots crash a flower-viewing party only to be cut down samurai-style by a young girl in a kimono and traditional hakama pants.

He's assigned to a base in Tokyo, but soon discovers that his headquarters is the Imperial Theater and his first mission is collecting tickets at the gate. He gamely goes about his menial jobs at the theater, surrounded by beautiful girls who seem to know a lot more about what's going on than he does, but he's about to be swept into a roiling world of robots, demons, and hot girls in uniform.
