The History of Zeta Leticulan

Hey, you're the one that helped me eliminate グレイ from Kulan Field, and gathered up ノートs for me, right?? We just finished deciphering ノートs, and we found some very astounding information inside, and frankly, I don't know how to react. Will you help me out here?

Thanks for saying yes. The deciphered ノートs confirms our fears, in that the Grays had a reason for invading Omega Sector and Ludibrium. Apparently, the place where they live is currently filled with lethal dose of contaminants, and, fearing for their lives, decided to move here as the next habitat.

I think it's essential to find out how lethal those contaminants are to them. Please defeat グレイ, ジェットグレイ, ウルトラグレイ, and 元老グレイ at Kulan Field, after which you should take a sample of DNA, each and every one of them.

Really...? I understand. Everyone seems to get a tad hesitant when dealing with ugly aliens like them. If you ever change your mind, however, I'll be right here.

Whoa... this is it! With this sample, the conducted the studies that are taking place in Omega Sector will be reinvigorated with results! I am also at a loss for words for finding someone that is more talented than me at hunting. I'll have to get back on track! Anyway, for your job well done, I'll have to reward you accordingly.

Here, please select the scroll of your choice. All success rates are at 10%.

I don't think you have gathered the DNA samples of the following Grays: グレイのDNA, ジェットグレイのDNA, ウルトラグレイのDNA, and 元老グレイのDNA. Please gather up at least 1 of each, which can be found by defeating the particular Gray. Good luck!
