I
Once
Saw this
Series, a few
Years ago, but I
Can't remember the
Name. All I know is that
Two highschool dudes were
Somehow transported to another
World of something, and in order to
Fight they have to exchange body fluids,
Like kissing or somesuch, and this female thing
Would get enough power and fight monsters for them.
It is killing me that I can't remember the name of it, so if
Someone knows it, tell me please. Thank you in advance ^_^

Sounds like Love Quest.

Thank You ^_^
