Campaign Creations

Hello!
I'm playing chapter 5 of the first book and I have a little problem. In the quest window I see two optional quests. The second one is Ayame's, but I can't find the first one. I explored the whole map but I didn't find it anywhere. Can you tell me what quest it is and how can I trigger it, please?

I think the first quest was 'runner'. You will have to kill him when he appears at the upper left of the stage..

I think this appears when you enter resistance base and raze it quite a bit?

Thank you!
I didn't attack the center base because it was very difficult to fight against Nekurow and Johan with the army stuck in that tiny ramp. I found much easier to wait for the big attack and counter it. But it seems the first quest triggers only if you defeat Nekurow or Johan before the Resistance's mass assault.
