Mr.Jester

The voice made the four's mentality shake even further. But the blonde man managed to recollect himself in time and shouted:

"Get yourselves together! We're clearly under attack!"

"What do we do, boss?"

The blonde man scanned his surroundings, then commanded:

"These rats are just mundane animals. There's nothing to be afraid of. We just need to group up and start killing them one by one."

The woman agreed and the two approached the lightbulb head and tall man. They quickly briefed their plan and the four stood next to each other, back to back.

[Hahaha...squirm while you can, little rats. There's no escape anyway.]
