The Man in the Black Suit

...I would say I don't know that person, but I can see I can't fool you. What I am about to tell you is not to leave Omega Sector. Is that clear? If so, I'll tell you about コリン.

I wish I could say I have no knowledge of that person, but looking at you, I don't think that's going to work. Alright, then, I'll tell you everything I know about her. Before that, though, can you please promise me that you won't tell anyone anything about matters regarding コリン, myself included?

Okay, then. I'll spill out everything I know. I've actually been well aware of the fact that she'd been declared missing, but by then, it was past our hands. All we could do afterwards was to just hope for her safe return.

She was kidnapped by the aliens that invaded Omega Sector. I'm guessing she was kidnapped by ガンティアン, since she lost her memory.

They probably tried to lock down the place by kidnapping a few residents. You can find 記憶のかけら containing コリン's memories from the battle with ガンティアン on Boswell Field. They might be of some use.

Please gather up 5 Pieces of Memory for me, so I can put them all together for you. Now, I trust that you keep all this information to yourself. Please head over to Boswell Field and face them. They are difficult to fight against, so I advise you to be on your toes at all times.

This is classified information, and it's a dangerous mission, to say the least, so I cannot stress this enough, but please do not reveal this information to anyone. I cannot talk to you about anything unless you promise to keep this information a secret. Well then, I'll have to get back to work, so if you'll excuse me...

Great job taking down the ガンティアンs at the Boswell Field and collecting 5 Pieces of Memory in the process. Alright, then. I'll try to put these pieces together and make it a whole. Here are some Mesos as a sign of thanks for taking out some aliens for us.

You did will, but...these memories are badly damaged. You could take this to コリン and regain some memories, but I can't say what effect the damage might have. It may be better to leave those memories behind...

You could try to find another way to retrieve the memories.

Or it might be better...to live without them.

I don't think you have collected all the pieces of コリン's lost memory. Please head over to the Boswell field near the Omega Sector and defeat ガンティアン, in order to collect 5 Pieces of Memory to recover コリン's memory.
