Re: ボクのために戦って負けて犯されて!? Translation
To be honest, I'm not sure. The game implies that there is some sort of challenge in hard mode, where you have to finish the game within some kind of time or move limit, but I never found it what it meant. I do playtest the games I translate to check about bugs, but I never get to 100% them so....you could find out yourself!
The Challenge is that you complete Hard mode within 28 peddler runs. It was a complete B*TCH trying to get it before, but I managed to get it all before the final run.
The difficult part was that a couple of mercenaries (Mage & Final Knight) had to do the full three runs in order to gather their trusts to 100. Then you're able to get the extra scenes in any way.
Edit: the most problematic mercenary was Rachel (the first merc from the intro). As the bonus girl, she was VERY STRONG in the latter runs. Just when I thought I had gotten her the 2nd time, she went out and bought a freakin tentacle armor that practically boost all her stats to nearly 3000 and she kept one-shotting everything. I was lucky enough to just curse her and had utilized every trap, poison, & weapon sabotage to get her final scene. After Breaking her spirit the 3rd time, I feel like a complete douche....no, a complete asshat for doing that.
Hint: in order to get all of the Final Knight's scenes (including the final public humiliations) you need to have enough money to purchase the love potion for 2000, plus have the other three items that raises the trust levels. All of those 4 items, plus the three peddler runs, will make sure she'll fully trust you at 200. That's when you hire the King from the merchant in the Pub and then do the 4th run while remaining at 200 trust. When you face off against the King, you can know use the move Surrender and finally get those last scenes.
One more thing is that you can gain addition, yet expensive Items from the West side area depending on the mercenary you take along with you. I had to do multiple runs to find out the best route possible, but I got all of the items from every female.
