Warning: This chapter is more violent than the other two. Issei murders two people here. Don't worry, none of the girls. Rated R. Be warned. And enjoy.

The occult research clubroom was becoming colder by the minute. The old building itself appeared to be holding its breath. Akeno served green tea to Issei while he sat on the black couch. Even though no one said anything, Issei could easily tell they knew something about what happened to Rias. He was sure they didn't know it was him that did anything, though, just that he was involved in some form. He wondered what they suspected he knew.

"I won't have to wait long to find out." He thought, smiling to himself. Akeno, who was watching him intently while sitting opposite to him, noticed his smile and decided to speak.

"Well then, Issei-kun. What business did you have here? Did you come to meet the president?" She inquired, holding her pleasant smile.

Issei had already prepared his answer beforehand. So he decided to get to the point right away.

"I know what you are, sister of Maou Serafall Leviathan. I also know you are unfairly controlling this school. And I can't have you stay here anymore. But I still need your powers, so I suggest you give me them quietly."

Akeno looked surprised, but only for a moment. Whatever she had expected from him, it was clearly not this. She decided to answer without any hostility anyway.

"I can't do that Issei–kun. This is the President's territory. She can do whatever she wants here. We stay here. And as for giving you my power, how do you suggest I give them to you?"

"You can do both, actually. And I don't mean just you. I want all of you to leave and never return. As for your powers, you don't have to do anything; I will take them if you just do not resist the drain. Oh, and as for this being your President's territory, she is no longer a high-class devil. I took her powers and made her my slave. So this is now my territory."

Without pausing as his words shocked everyone in the student council room, he pulled out his smartphone, the one that he go from Rias, and showed her the photo of Rias and Raynare in a cage, shackled and chained.

The reaction was instantaneous, Kiba Yuuto, Rias's Knight, charged with blinding speed and slashed with his sword. Issei barely dodged it. Even though he had the power of a high-class devil now, it was still nowhere near enough to challenge someone with an evil piece who had the training to use it properly. But in the last week, he had used the knowledge of Ddraig and came up with a few techniques that utilized his Bishop piece, the piece that enhanced demonic power. The sword clanged and reflected off the barrier that he had set up around himself, Kiba tumbled from the momentum. But before he could strike again, the school mascot, Koneko kicked at his face, the barrier, already weak from Kiba's attack, shattered but absorbed most of the force. Issei didn't waste his time, he began the draining process again, beginning with Akeno, but before it went anywhere, Akeno herself shouted,

"Stop. Everyone. He has Rias hostage." Even though Issei hadn't considered using Rias as a hostage, as he wanted to fight all of them at once to get some live combat experience, Akeno ruined it by asking everyone to stop.

"Where is Rias-san?" Asked Yuuto Kiba, holding up his undamaged blade and pointing it at Issei.

Issei didn't answer. His plan to fight them directly was no longer viable. He decided to change tactics.

"She is safe. But if you do not hand over your powers right now, she will not be." Issei replied.

Yuuto smiled confidently,

"That will not be possible. I will defeat you here, right now, and force you to free her. I am her knight, I will protect her" He charged again, ignoring Akeno's order. Koneko also followed. Issei decided to use his trump card,

"BOOST BOOST BOOST BOOST"

His abilities multiplied, and he evaded Yuuto's sword, but before he could punch him, Kenoko delivered her strike to his stomach, sending him flying against the wall. Yuuto continued his assault, not giving Issei the time to recover and attack. To make matters worse, Akeno also joined the fight, attacking with multiple types of elemental attacks. The three of them pushed Issei back, who had little experience defending himself from three opponents at once. Thankfully he had his sacred gear, otherwise, he would have been killed by now. As Akeno charged her strongest attack, Issei restarted the absorption process, deciding to absorb their power little by little. Before he could go further with this plan, Ddraig spoke in his mind.

"Partner, don't absorb her power. Target the swordsman, he has a very versatile sacred gear, if you combine it with your power of the Bishop piece then you can become a versatile opponent yourself for them. But be careful, he appears to have the souls of his comrades with him, I think he has another balance breaker and sacred gear that he didn't manage to activate."

Issei did what Ddraig advised. The sacred gear began draining Kiba's energy and all of his latent potential, while the three continued to push him back. Issei countered as well as he could, which wasn't much. But after a while, Yuuto's strike began to weaken, Akeno and Koneko noticed it too, for they stopped their relentless assault and tried to figure out what was happening to Kiba.

Issei used this opportunity to rip away his sacred gear without anyone interfering with his concentration, feeling tired from both the attack of the three and having to use two sacred gear at once.

Yuuto hit the floor as the sacred gears left his body, Akeno and Koneko rushed over to make sure he was okay. Issei didn't attack them, instead letting them talk. He quietly began draining the energy of Gasper, who was in the next room, and decided to end him for good. There was still something left in him and the powerset wasn't complete with it.

Akeno looked on in concern when Yuuto tried to speak, but no word came out. Wondering what happened, she tried to use her demonic power to heal him but suddenly noticed that her energy was very low. That made her pause, she had only used a part of it in the fight, and she should still have enough left. Before she could ponder on it though, Yuuto finally began to speak, to her surprise, he began to speak to Issei, not her.

"You really are the lowest. Attacking a woman….." Before he could finish, however, Issei hit him with a ball of fire followed by a destructive wave of flames that completely obliterated his body. Looking coldly at Akeno, he stated,

"He talks about how I shouldn't attack a woman yet doesn't mention how she tried to enslave me. I am tired of people telling me how to live. I will kill anyone who tries to tell me what to do."

Akeno attacked him in a blind rage and thus didn't notice that her power has diminished to almost nothing. Issei tossed her away by throwing Koneko at her, having caught her trying to attack him from the back, the force blasted her and Akeno through the wall where Gasper was in a coma, and now lay dead. Recovering from the attack within moments, Akeno noticed the last sliver of her power drain away as Issei began absorbing Koneko's power. She then noticed something that frightened her even more.

"Gasper-kun". She exclaimed, causing Koneko to look at him as well. Forgetting about attacking Issei for a moment, she walked over to the sofa as Akeno did the same.

"What did you do to Gasper-kun?" She demanded, looking at Issei with rage and a bit of fear.

"I killed him."

Issei said,

"he had no use to me anymore. And he would have supported your plan to enslave me."

Koneko looked even more enraged.

"He had nothing to with it" She screamed.

"You killed him over nothing, I will never forgive you. First Kib-kun now Gasper…."

"Oh yes, he did. He had been tracking my online activity for a while on Rias order. She told him everything, and he went with it." Issei interrupted her, no longer having the patience to listen to more lies.

"He …but he…." Koneko mumbled and then stopped, having realized the truth in Issei's words.

"He what, exactly?", Issei asked, his anger getting the better of him, "He was in on the plan to enslave me. I should have burned him down like that guy." Issei began to yell too, his rage taking over his common sense.

Ddraig suddenly interrupted,

"Partner, you should leave now, you are nearly at your limit. The energy you absorbed made up for using the sacred gear. But you still have only a bit left. You should wrap this up right now."

Issei didn't care. He wanted to rip Koneko into pieces. His common senses were clouded with blind rage, just like the two girls at the loss of their comrades. Charging a large fireball, he suddenly stopped and looked toward his left arm. The sacred gear that appeared there was one he didn't recognize, it looked similar to his boosted gear but White. Even as he watched, it vanished.

"Ddraig, what happened?" What was that?" Issei asked, ignoring as Akeno said something to Koneko, who shook her head.

"That was a danger signal. It was probably an effect of the power you developed after you absorbed the vampire's powers. The time-manipulating sacred gear appears to have been doing something weird, forecasting the future, maybe. I can't be sure." Ddraig answered, confused himself.

Issei was distracted. He decided to concentrate to learn what his sacred gear had analyzed, not noticing the conversation that was going on between the two girls. Before he could learn anything, though, he noticed a sharp decrease in his power as the boosted gear released itself. Exhaustion hit him, and he suddenly dropped to his knees, no longer having enough energy to even stand. Akeno however either didn't care to attack him in his vulnerable state or didn't have enough power to.

"Partner. This is enough. Leave this place now. Your body still hasn't adapted to your powers. Any more and you will start to damage it. You can always capture them later" Ddraig warned him again.

This time, Issei listened. He wanted to live. He wanted revenge. Dying here will not accomplish that. He decided to stop the fight. Looking at where the three were, he was surprised to see Koneko was being dragged away by Akeno as they tried to escape, but Koneko was against leaving Gasper's body. Deciding not to pay them any attention and focusing on recovering, he suddenly had another idea. It was true that he was exhausted, but he still had another card left. He called out to the two fleeing girls,

"I still have Rias. Do you want to leave her too?"

That made both of them stop. Seeing that his plan was working, Issei continued,

"You are leaving Gasper because he is dead, but Rias isn't. Do you want to leave her too? She will be sad when she learns it. Come with me, become my servant, and you will see each other again. If you run, I will humiliate and harass her every day. She is a devil. They live for 10000 years. I know. She told me. Wonder if her mind will last that long? You don't want to be responsible for that, do you?"

Akeno and Koneko both paused. Then Akono decided to go forward with her plan, which wasn't much other than trying to talk Issei down.

"What do you want Issei-kun? You already took our powers, and it appears you already took Gasper's power and you killed two of our friends right now. Is there anything else you need?" She asked angrily. But she still controlled her voice, or tried to. The anger was still there. But she also knew angering him will not accomplish anything now. What it will do was make Rias, even more, worse than she is right now.

"Yes, there is, in fact, another thing. Don't need you anymore, but for my mental satisfaction, I want both of you as my slave, I want to see how you like it when the shoe is on the other foot. And this is the last time I will ask. I am getting tired of having to explain it again and again. You are smart, Akeno-san. Surely you know nothing good will come out of refusing me." Issei replied calmly.

"I won't do it."

Koneko replied angrily. But Akeno looked confused,

"Is that why you took Rias?" She asked. "Just for your mental peace?"

"Yes. And she is planning to escape. But let me tell you she won't succeed. And neither will the Fallen Angel." Issei replied.

"But Issei kun, is that all you want?" Akeno inquired.

"No. I will destroy all devils and fallen angels and well as the Angels. They tried controlling my life. I will get revenge." Issei replied, anger coming back in his voice as he thought of all the things they did to him.

"That will not work. Issei-san. Her brother is the strongest Maou. A super devil. You can't beat him. But he will blast you to dust."

Issei looked toward the source of the new voice. The school council president and her peerage have arrived. The sound of the battle and the demonic powers used have alerted them to the situation. The one who spoke Sona Sitri, fixed him with a deadly look and continued,

"But that will not be necessary. I will eliminate you here and now for hurting my childhood friend."
