This enraged Issei instantly. To hear that this guy raped an Angel and has no regrets of it made him sick to his stomach.
"Alright this guy is a sicko. I'm not gonna bother spend much time with him so I'll make it quick" Issei said.
"Oh this is hilarious. You think that you can beat THE Freed Sellzen!?" He retorts. "I'll chop you to pieces!"
Freed lunged at Issei but it didn't faze him one bit. All Issei did was raise his left arm and said 3 simple words. "Chains of Shadows". At that a large portal appeared below Freed and out of it came chains that launched at him.
"What!? What are you doing to me!?" He asks, desperately trying to free himself from the chains.
Issei walks up to the chained down Freed and raises his hand. "Trash like you doesn't deserve the easy punishment of death. For all the sins you have committed you shall spend eternity suffering in the Prison of Shadows. Goodbye". With a snap of his finger the chains bring Freed down into the portal, devouring him and making him suffer, without the privilege of being killed.
Issei continued to stand there, clearly still enraged while Raynare and Kalawarner stood there, shocked on how Issei had decided to deal with Freed. Unlike Rias and Sona, the two Fallen Angels don't have any idea of his past or his power.
After the passing of the shock Raynare decided to walk up to him and give him a hug from the back. She didn't like the more brutal side of his, she wanted him to be the sweet guy who took him on that wonderful date a few days ago.
"Issei" She said. "This isn't like you. Please bring back the man I fell in love with"
Once contact was made between the two he slowly began to calm down. The anger within him began to subside and his carefree side began to return.
"Why did you go this far?" She asked. "Why didn't you just kill him?"
"He didn't deserve the luxury of death" Issei replied. "After what he did he deserves to suffer"
"But why did you get so enraged after I told you what he did?" Kalawarner asked.
Issei was very hesitant to answer but he decided that they deserved to know. "A few years ago when I first started to train and get stronger I was attacked by a group of Fallen Angels. I fought long and hard but I couldn't last that long. Once they were about to finish me an Angel came down and saved my life. She took care of me for the next few days until I left. I guess it angered me that Freed could have done that to a pure Fallen Angel and had no regrets of it"
"If Fallen Angels have caused you pain then why do you treat us nicely" Kalawarner asked.
"Over time I learned that not all Fallen Angels are evil. Like you two there can be good Fallen Angels who I can care about"
Raynare instantly began to blush when Issei said that he cared about her. It crossed her mind that maybe the two could be together in the future.
"If the two of you are done flirting around we have a nun to save" Kalawarner said.
"We weren't flirting!" Raynare retorted.
"Yeah yeah whatever lets just get to work" Replied Kalawarner.
"And where exactly are the rest of the exorcist?" Issei asked.
"They should be in the hidden chamber down stairs. I know the way down follow me"
Issei followed the Fallen Angels to the hidden stairway in the center of the church to hear screams echoing from the bottom.
"The ritual is almost over we need to hurry!" Raynare exclaimed.
The trio ran down the stairwell and saw dozens of rouge exorcist around a male Fallen Angel holding a green orb of light with two rings in it. The screams of the girl was dying down and her body was lifeless.
"You're too late" The man said. "Twilight Healing is now mine and no one can stop me!"
"That's where you're wrong Dohnaseek!" Kalawarner replied. "By the time the sun rises you and the rest of these traitors will be begging for mercy"
"Oh is that so? Its only 3 of you against my army. You can't defeat us"
"Wrong once again!" Said a voice behind the trio.
Issei and the two Fallen Angels looked behind them and saw Rias and her peerage, all in a battle stance.
"Ah the heir of Gremory its an honor to be in your presence" Dohnaseek said mockingly.
"Its quite contradictory to say that after capturing an exiled nun and stealing her sacred gear now isn't it?" She said.
"Well I guess you could say that but it won't matter after you're all dead. Kill them!" Dohnaseek ordered.
"Go my servants and show them what happens when you mess with the house of Gremory" Rias commanded.
"Yes president" Her peerage said.
The 3 servants went on to attack all the exorcist, cutting them down in a quick fashion.
"Now if you don't mind i'm gonna deal with their leader" Issei said, summoning two swords of darkness in each of his hands.
"Try not to hurt him too much Issei" Rias requested.
"No promises" Issei winked.
Issei finally released his dragon wings which consisted of four total wings. Two of the wings were purely white with beautiful scales on them both. The other two wings were as black as shadows and within the scales had Ophis' signature infinity sign.
He flew directly at Dohnaseek and swung his swords at him. The swords clashed with Dohnaseeks spear of light but surprisingly to him the spear shattered.
Dohnaseek flew into the hair, dodging any other attacks that came his way.
"What's the matter Dohnaseek, you scared already?" Issei taunted.
"Shut up you worthless dragon! I'll slay you where you stand" Dohnaseek yelled in rage.
