Apparently you can snipe kills from your friends battles. Get the killing blow and you get a present! Not a bad way get more rewards, let them do most of the leg work! I'm not sure if the person who found the girl who gets anything...hopefully they do. If not I'm a terrible person! I did do 1 hit throughout a whole fight but not the killing blow and didn't get anything, I'll continue to test this.

-UPDATE-
So actually you do get a reward even if you only hit the girl once not sure if the top contributors get better rewards yet but I did get 10,000 pero just from 1 hit on a girl and I was rank 3 for overall damage! Also I did let someone get the just the killing blow on mine and got a reward of a peronamin N Wild and R Wild. Looks like the best thing to do is to share your girls with your friends so all reap the rewards!

Dropped rewards are static amounts.

Normal Guard gives 2 for the finder, and 1 for supporters.
Super Guards give 3 for the finder, and 2 for supporters.

The bonus you get for things like MVP and Killing blow are EP multipliers.

I'm actually still on the fence if I want to go for dropped rewards, or EP for ranking.

Well, really feels like I'm not getting most of my support EP rewarded.

Yea, its definitely seeming like you get screwed over as support unless you land the killing blow

Anyone figure out how to use the sexual energy drinks? I bought one because I ran into one of those 9 MILLION health bosses and the option to use it is greyed out! WTF NUTAKU I WANT MY 5000 PERO BACK!

You have to use them before you attack the boss.

lol at least I know for next time. This girl was rather expensive to take down but dang that is some nice EP!
