When Jack used his companion token, Arlcard didn't immediately appear. Arlcard even asked if it was an emergency. He'd just come out of his cocoon and was still trying to grasp his improvement. Jack told him that it was a bloody emergency. They were in a war and they could lose if he didn't come.
Jack could hear Arlcard's sigh when he received the notification that his companion had accepted his call.
'Bloody heck. I wonder if others ever experienced such a thing when they called their companions,' Jack complained in his mind.
A dark slit appeared in the air in front of him. Out of this slit, thousands of bats rushed out. These bats hit the zombies Jack was fighting. Upon impact, the bats dissolved into shadows that covered the zombies' bodies. The zombies stopped moving afterward. Damage numbers came up on those zombies every second.
