Rin scowled at the piece of paper. Each had been asked to try and summon a demon. If they were successful, they had potential to be Tamers. Rin didn't care about that. He knew he would be fine as a Knight. But of course... There was something about the paper. He wanted his blood on it. No, inside the circle.
He witnessed Shiemi being successful with her little Greenman. And Izumi was doubly so with her fox spirits. None of the boys were successful.
"Oi! Okumura! You going to summon anything?" Bon called out. Rin glared at him.
"Can't. Guess it's not for me," Rin responded with a slightly cocky tone.
"But you haven't even used your paper yet," Shima pointed out. Rin glared at the usually lovable pervert.
"You want me to try and summon," Rin growled. He grabbed a pin and broke the skin on his finger, barely bleeding, rubbing his blood on the paper.
"From the sins abound, and Devils play, killers of commandments far and wide, the seven wrought and animals brought-Take what's mine!" Rin called out. Nothing seemed to occur. Rin chuckled at the nonsense he spouted.
"Man, I can't believe you guys believed that."
"Knock it off you bastard," Bon grumbled. No one noticed the paper symbol beginning to glow. It was only when the room had been overwhelmed by smoke. The children began coughing. Professor Neuhaus attempted to leap into action only to be pinned to the wall. He gasped and a deep chuckle was heard throughout the room.
"Merlin? I swear if this is one of your jokes..." A bored voice mentioned offhandedly as the smoke dissipated. A tall man stood, holding their teacher to the wall. His hair, a wild silver-white. He had a tight red leather outfit with silver studs. He had one hand on their teacher's neck lazily and he gazed over the group with little interest.
"Little things aren't you," the man said without interest. Red eyes not telling anything but boredom.
"O-Okumura! Control him!"
The white haired man raised an eyebrow and followed where the loud one had called. His eyes narrowed on the dark blue haired boy. He inhaled slightly. A cocky grin came to his face as he let go of the teacher. Faster than anyone could blink, the man was behind Rin, an arm slung over his shoulder and put his head next to the young exorcist in training.
"Control me? You? Not even Master can control me. You're welcome to try though."
"Gah! Who are you?" Rin yelped. He tried to pull away from the man but the grip of the summon was far greater than he expected.
"Names Ban. But you might know me as the Fox Sin of Greed," he said with a sharp toothed grin. His red eyes landed on Rin's sword. His smile grew even larger, "And if I had to guess, you brats are a bunch of Holy Knight Squires right?"
A one shot idea with the little prompt below.
Blue Exorcist X Seven Deadly Sins
Rin is attempting to summon. Everyone is surprised when out pops a "unique" individual. One of the seven sins.
Rule 1. Rin summons one of the seven sins... Or an equivalent character
Rule 2. The sin/equivalent character won't leave Rin alone.
Really, I think it would just be funny.
