Starting the Raid

Five minutes before they reached the destination, all the participants had been assembled in the cabin, including the explorers under the OpenSky Company. 

There was a 19-year-old man giving them the briefing for this raid.

"As you already know, we'll be targeting the seven Tier 3 beasts in this place. Our teams will also be participating and we will do our best to keep you from getting into danger.

"Next is this…" The man raised a flare gun. "Shoot the flare to the sky if you want to get rescued or notice something wrong. We'll immediately send our team there.

"While we do our best to help you, it'll be hard to keep track of all the people. Hence, I'll set up perimeters. Anyone who crosses this line can consider themselves eliminated. If there is any beast coming over to you, we won't be able to come to you right away." The man drew two straight lines parallel to each other.
