Hmmmm, if you consider a manga a book, well.....
(unlimited bursts of)
Blood (not AL)
GORE(tear-jerking)
Drama(non-awkward)
Comedy (like omfg i did not see that one coming)
Twists (a little bit)
Fantasy (more)
Medieval and (less -- or none at all)
Futuristic(top of the notch, hardcore and kick-ass)
Action Ecchi (spices up the mood a lil bit)
SEX (one reason why i <3 reading
AIKI and
UBEL BLATT --- oh and add smexy Magical Elves and Fairies to that...... however, I won't like it if it's mostly you-know-what... if it is, it's plainly Hentai)
ROMANCE (does romance between Siblings, Inu/Neko girls, Multiple girls X one lucky guy, or same gender count?)
Violence (may it be serious or downright senseless)
and with
Main protagonists who are already owning and pawning antagonists' asses even at the start (AIKI and Kaze no Stigma for example --- hate those DBZ types wherein the protagonists are weaker when they face a starting foe and become stronger to defeat them then only to appear weaker again after a new enemy comes along then the cycle repeats itself... like BLEACH -- but hey, I like it still... but it's kind of a let down)
Other tastes of genre include:>
Slice of Life and School life>
Gender Bender (Hanazakari no Kimitachi e/Hanakimi and Power FTW)>
BL (shounen-ai --- I blame my SIS, Mina, for making me hooked.. wtf)>
HAREM (slash ji ji)>
Psychological, Mystery and with a little Horror (loved Ono Fuyumi's works -- novelist behind Ghost Hound)>
Josei (more explicit and mature than shoujo)>
Historical (perhaps... or could be a Historical Parody, such as GINTAMA)>
Girls after Guys (like Nagasarete Airantou, To-Love-Ru, Sekirei --- it's as if they're asking for it
)>
Futanari (.............. i don't know why the hell i wrote this)
