Eliminating Chief Gray

You're the one that helped me get rid of グレイ the other day at the Kulan Field, right? The research on the force controlling them is just about to be concluded, and it's taken longer than expected, but I'm glad you're here now. I have something else to ask you for a favor. Will that be alright? Would you like to at least take a listen?

Thank you for all your help. Did you know that there are ranks even amongst the Grays? We've found out about high-ranking Grays that have jurisdiction over the other Grays in this area. Each is called a 元老グレイ. There's not that many of them amongst the Grays, so it was really difficult to track them down. Anyway, they should probably be in クーラン草原4 and クーラン草原5.

Can you defeat these 元老グレイ aliens and bring back 5 of their ノート things? I think each ノート contains some very valuable information. Come back to me when you have 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.

Ah, you got the ノート! It took me a while just to find those guys... I guess I need to work harder! Anyway, here's your reward for helping out! I know this isn't much, but please take it!

Thank you so much. Now, let's try to decipher this note. Just as I thought, this is written in alien language, so it's near impossible to understand what's written here, but with a little time, I'm confident that we can decipher this book. I gotta get this going, so I'll see you around!

It seems like you're still missing a ノート or two. Go find the high-ranking 元老グレイ, get their ノート, and come back. ノート probably contains some juicy secrets!
