Thanks guys, I finished the game earlier today. It was a little confusing at first, but google translate helps.

The goal of the game is to steal a crown in order to become rich. Somehow raping a bunch of women facilitates this process. Your team is Kandar (who you might remember from Dragon Quest III), and three generic henchmen (don't let the identical sprites fool you, first one is a warrior, second one is a cleric, third one is a wizard.)

Some tips: When fighting females, eliminate all male companions she might have. Once they're gone, have Kandar use his Sexual Harassment ability (in the second one in the spell menu,) and have the henchman go on the defensive, defending, healing, buffing, etc. When a girl is attacked by sexual harassment, she cannot act. After a few turns of this, you hear a weird "spriong" sound and she is defeated. Sometimes she manages to escape, and you need to attack her with the ability again. Practically all females you battle need to be defeated this way in order to get the bonus h-scenes.

Some girls you don't battle directly, just their bodyguards. You can defeat these goons normally.

The hardest boss I faced was Maya and Meena. They're fond of status effects. I got trashed the first time around, but I find that using sexual harassment on Maya (she is the dancer, right?) seems to be more effective then targeting Meena the Fortune Teller.

For the final boss, try to focus on harassing the Heroine and the Martial Artist first. They seem to be the hardest hitters.

Make sure to look in all barrels, pots, bookcases, etc. "H medals" are hidden in these. You trade these to a guy in the basement of your hideout and get rewarded with H-scenes of the bunnygirls. There are 30 total H medals in the game, but I only manged to find 28 of them. Make sure to talk to everyone! One of the prisoners in a jail cell rewards you with an H medal, while others give you keys you need to progress though the game.

I hope that helps you enjoy the game!

P.S. If someone finds all the H medals, could you post their locations? I'm backtracking all over the place and going bonkers looking for those stupid things.

Edit: thanks a million, Ryuukami123
