Fighting a ranked B demon isn't an easy task. Especially one who views your attack as invulnerable. From the sides to the top, then bottom, it would all be useless if a plan, a solid plan, hadn't been prepared.
Vin knew this when he saw the laughing demon, whose length and width, exceeded the vivid imagination he had.
"Make it cry?" Ruyika asked. He might not know Magic or anything regarding this, but he was an excellent swordsman, which made him useful in this battle.
"Yes. A laughing Demon's weak spot is within. A core which when touched, would make it cry" Vin explained, while he kept a good look, monitoring the Demon.
"A core you say?" Ruyika narrowed his eyes, "Where can the core be found?"
"That's the main problem," Vin said, "This core isn't in a fixed place. And even if, we won't be able to find it on time, without proper navigation."
"How big is this core?"
"About the size of a marble"
"I see."
