since you like love monster...ummm try:
high school of the dead = mix of all zombie movies and games with a touch of ecchi and harem
card captor sakura is pretty cute and sweet but dunno if you can still download the manga version...anime you still can though
Rurouni Kenshin has some romance in it and there's lots of action.
I'd recommend Saiyuki or Fushigi Yuugi. .
