Issei followed after Azezel timidly but with the trust that he would help him save Rias from that monster of a devil. The wedding was scheduled for ten days from now and he didn't know what else to do. So he called up Azezel, whose number he had got after he hung out with him before as a part of a devil contract and asked him to help. They had lost soundly in the rating games and the only hope he had was to defeat the regenerating ass-wipe in a death or forfeit duel before the wedding, as explained very clearly to him by Serzechs Wife and Queen when he asked after Riser left.
"So where exactly are we going?" Issai asked as he followed Azezel down what looked like a hospital corridor even though he knew he was far underground as they took the elevator down here after teleporting.
"To a scientist of the Grigori, thee scientist of the Grigori actually," the black and gold haired man said with a small smile at the obviously pent up and worried little pervert. "He's been studying the old bloodlines of the devils for quite some time now and he believes he's found a way to impart a bit of their power to a young...willing individual." Smirking again at the smaller sacred gear user as they finally got to the end of the hallway and entered through a set of doors as he swiped a keycard. He loved researching interactions and abilities when he had the time and this was perfect.
Issei looked around in awe and a little bit of worry. The stark white room was filled with an array of tables with different jars, instruments and medical tools. He shivered as he saw what looked like organs, eyes, and even flesh inside the jars. Steeling his gaze as he reminded himself that this was for Rias and her absolutely perfect pair of Chesticles he continued into the room with Azezel. Near the far side of the room a man was standing next to what looked like a large stretcher with straps to keep someone down. The man turned as they approached and smiled a small kind smile. He was an older looking gentleman who had short white hair and kind brown eyes that crinkled a little with his smile wearing what looked like a doctors uniform.
"Dr. Kanou, nice to meet you young man," he said as he shook Issei's hand, "I heard you might be willing to be my first patient in these trials." His look of mild embarrassment as he said first unnerved Issei a bit but he still grasped his hand firmly as he responded.
"Yes sir. Anything to help me save Rias"
"Anything you say...good good." He's gestured at the nearby table with surgical tools and a jar with a small red organ inside. "This is what I'm hoping will give you edge you need my child. It's a very special organ taken from the last of its lineage at the time of his hmm...death. The Great Devil House Ghoul according to my research had their lines abilities come from this mutated organ. Which I am hoping will be able to be implanted with no complications in you."
"What do you need me to do?" asked Issei. He felt his nerves shake a little but trusted that this was his best chance.
"Take off your shirt and relax on this table, back up, young Hyodou."
"I'll leave you two to it then," said Azezel as he put his hand on Issei's shoulder leaning over a bit to look him in the eye, "Good luck Issei," was all he said with a momentary serious look in his eyes before smiling and walking back toward the doors. 'You might very well need it for this to work,' he thought to himself as he left swiftly, to return in a few days time.
