Terminating the Dark Force.

I've been waiting for you to come back here. Utilizing the power of a language expert, I've been able to research 葛雷文件 for the last few days. Through that, I found out something that may interest you... and of course, I'll need your help once more. What do you think... do you want to do this?

The most important part of this is missing, so the perfect way to turn these 'monsters' back to dolls isn't available, yet. What we DO know is that the 黑暗母礦 that you'll find with 暗沉水晶 from time to time again has something to do with all this.

Go to the 67th floor of the Eos Tower again, defeat Drummer Bunnies, and return with 30 暗沉水晶s. This should pose no problem for you. I'll be waiting.

I thought I could count on you to take care of this mission, but I guess not. This is a discreet project, one that cannot be advertised to total strangers, so... if you ever change your mind about this, then please talk to me, okay?

Hmmm... okay! I can try different things with this many to work with. Here... I have to reward you well for your job well done. I'm a general, so if you want anything, just say it. Hmmm? You don't need anything right now? Hahaha... I understand. Here, please take this!

I can't thank you enough for helping me out this much. I'll never forget all your help. This doesn't mean everything's been solved, but I can safely say that the path to a solution has now been established. Hope to see you around here from time to time again. Bye.

I'm still waiting. Go to the 67th floor of the Eos Tower again, defeat Drummer Bunnies, and return with 30 暗沉水晶s. This should pose no problem for you. Good luck.
