Traitor

In the Lab Dungeon, before the battle between Kuzu and the trio. 

Kamiya pulled a folding chair from the pile, unfolded it, and sat next to Hitori. Reon was on his right while Hitori was on his left. 

"One of the most important things that I want you to keep in mind, always," Kamiya began, "is that: When we are in the Pontianak's courtyard, we have a defense shield that would protect us."

"For how long?" Reon asked, nervously. She cupped her hands together and pulled them on her lap, over her lab coat. 

"It depends." Kamiya turned to Reon and said, "on how long you are exposed to their weapons." Kamiya then glanced at Hitori. "It can shatter in a second if a forbidden weapon is used or it can last as long as half an hour if only normal bullets are used," he completed.

Hitori listened carefully to what Kamiya had to say. "What is the catch?" Hitori stopped nodding his head.
