Activating the epitaph device with Battler.

BATTLER: ......Gouge the foot......and kill. ......Now it's complete...
ERIKA: I see, ......so that's what 'gouge' meant after all. Once again, my reasoning was correct.
The reaction this last time was clearly different from the previous ones, making it feel as though some sort of device had activated.

However, as far as a quick glance could tell, there was no dramatic change, such as an entrance of some sort opening.
Apparently, they would need to do just a little more before they could find it...
BATTLER: You're incredible. .........After all this, if we really do find the gold, we'll have to split it together.
ERIKA: Enjoying the intellectual stimulation is enough for me. ............The only thing I like is solving riddles. Proof that I was right is all I need for a reward.
She shrugged it off, saying that just seeing the gold would be enough.

Then she crouched down, peering fixedly at the lock mechanism.
......It's no exaggeration at all......to say that this girl really loves solving riddles.
Her fondness for treasure hunting is fueled by a romanticism regarding the process of finding hidden things, and she has no interest whatsoever in getting the treasure for herself and becoming a billionaire or whatever......
ERIKA: ......I see. You really think such a device would fool me......The mistake 'you all' made was welcoming me onto the island in the first place. .........Simply by the existence of the epitaph in that place, this level of reasoning is possible for Furudo Erika. ......What do you think, everyone?
As she said this to the device she had exposed, she grinned at it.
That smile had a bit of triumph on it, but it was more fully characterized by the small bit of unpleasant disdain it contained.

After solving the riddle, she was probably reveling in the pleasure of having won against the one who had proposed it, as well as the way she could now scoff at this person......
ERIKA: .........If we find the gold now, the successor to the head won't be Krauss-san, but you.
BATTLER: Heh. ......Well, I wonder.
ERIKA: ......Isn't Krauss-san kind of arrogant? Maybe you could even call him a braggart. It'll be pretty pleasant to see him have both the gold and his position as successor to the head snatched away by his nephew in the course of a single night, won't it?
BATTLER: ...................
Erika was still crouched down as she spoke, her back to Battler as she toyed around with the device...
ERIKA: .........Jessica-san...was her name, right? The girl who spoke up against me.
BATTLER: Nn, ......yeah.
ERIKA: .........She really was acting big about her father being the successor to the head. ......When she wakes up tomorrow and learns that you've inherited all the gold and that her father is no longer the successor, I wonder what kind of expression she'll have on her face......?
BATTLER: .........It's not like I have any desire at all to keep all 20 billion for myself. ......Well, if I get even 10%, that'd be as much as I could handle. We can split the rest fairly amongst the family. I'm even less interested in being the successor to the head. I'd be glad to let Krauss oji-san deal with that.
ERIKA: .........Can you really settle things so easily in the end...? *giggle*giggle*giggle*. Instead of trying to predict that, ......I get the feeling it'll be much more fun to guess what kind of expression Jessica-san will have on her face tomorrow and what kind of sad excuses she'll try to make.
BATTLER: .........You...really have a bad personality.
ERIKA: Oh? .........Couldn't you reason that out from the time you learned that I liked solving riddles......? .........I'm an intellectual rapist who enjoys exposing things people try to hide, get it? ......Same thing goes for solving the riddle.
BATTLER: ......You probably wanted to expose the gold Grandfather had done everything he could do to hide.
ERIKA: Yes, that's how it was at first, ............but my goal changed halfway through.
BATTLER: Halfway through? ......Changed to what?
ERIKA: Jessica-san. .........She butted in on my reasoning, contaminating a pure and noble time for me. .........That's why I changed my goal into solving the riddle so that I could get even with this girl called Jessica.
BATTLER: ............Hey...are you serious?
ERIKA: *giggle*. .........*giggle*giggle*giggle*giggle*. ...I'll make any opponent surrender, no matter who. That is my sole pleasure. ......Do you need any more reasoning?
ERIKA: .........Ushiromiya Jessica irritated me. That's why I wanted to put her in her place and decided to solve the epitaph. .........That is what guided me to the emotions I hold now. ...Can you reason it out?
......This time, I turned my back on her in earnest.

...YUP.
