Servant, The president of the cult research club, along with all the club members were demons, Although he still didn't know exactly what a demon was, He knew they were different from fallen angels and the opposite of angels, hearing that proposal his mind could only go blank, Servant, what did that imply?, No First of all, Why was she asking him something like that?, How is he supposed to react now? After all she is asking him to align with her against the other factions, he still didn't know how many factions there were, But with the two she mentioned it was enough for him not to try to get involved, it was suicide for him to enter that world, It would be complete stupidity for him being so weak to join some side, Besides it would go against the new objective he set for himself

"If I reject your proposal, What will happen to me?"

As he backed away a little he asked that question, He knew who he was rejecting the proposal from, She was a demon, even just standing in front of her he knew how dangerous she was, even the dwarf had a strength that far surpassed his own, If she was just a servant, How powerful would her mistress be? It wouldn't be strange if she could kill him with just a finger lift, He didn't want to die, But he can't just accept that proposal and have several factions of different races looking for his head

Rias didn't look so surprised, it was an answer she didn't expect, Although she thought it was a possibility that he would answer like that

"Nothing really, If you refuse we will let you go right now"

As she said that, issei blinked in surprise, They would let him go, Just like that? He knew they were demons, Didn't they plan to silence him?, It didn't seem like she was lying, but it was too suspicious, He had information about something that in theory he shouldn't have being human, something was wrong, his instinct told him so, Even so he decided to ignore it, when he thought about leaving he heard rias continue talking

"We will leave you alone, But I couldn't be sure that the other factions will do the same, Less the faction of the fallen angels, You killed one of theirs, Remember?"

As he thought about turning around and leaving he heard those words, Right, The faction of the fallen angels, If they had a sense of camaraderie they would undoubtedly come to avenge yuuma's death. Demons or not. Whether he liked it or not. He was already involved in this. Looking at rias he asked her a question

"What benefit would I get from becoming your servant? All I see are disadvantages. If I join your side. Wouldn't I be in the same position as now?"

As he asked her that question he looked her in the eyes

"You're wrong. If you join me as my servant. The chances of another faction attacking you will drop considerably. Among demons there are structured ranks. The title of my family is very privileged in the underworld. Both fallen angels and angels won't be able to do anything to you if you carry the mark of my family"

As she said that. He could notice some annoyance and pride in her voice. So if he joins her his future problems will be solved? If so he wouldn't have any problems doing it. Although he still couldn't fully trust her statements

"I have a question. Why do you want to make me your servant? I don't think I have anything special. If you only take into account what happened with the fallen angel... anyone could have done it under my circumstances"

As he said that. His voice faltered a bit. Did she know about his power? If so. He would understand why she would want him on her side. But if she's only proposing this because of killing the fallen angel he would definitely distrust her. After all he doesn't believe that achievement is such a big deal. Anyone in their desperation would have done the same

"It's not just because of that. I'd say it's my instinct telling me I must make you my servant at all costs. Issei do you know the term sacred gear?"

That word again, Sacred gear, they had repeated it to him countless times but he still didn't really understand what it was, If it was what yuuma told him, then without a doubt rias knew that he had a power but, Did she know that he could come back from the dead?

"Yes, Yuu-, The fallen angel mentioned that word when he tried to kill me, He said it was a power that is granted to humans"

Although he stumbled a bit, He was able to answer, If she knew about his power, That would definitely be something to consider

"That's correct, You have a power that was granted to you by god, If you become a demon and use that power to help me fulfill my objectives, I in return will promise in my name and in the name of the gremory family, that I will do the same to help you fulfill your objectives"

With a serious voice she declared that, at that moment, issei felt overwhelmed, walked a little and sat next to kiba, He felt him put his hand on his shoulder, although he ignored him, With one hand on his forehead he started to think, Without a doubt it was a tempting offer, No, it was an excellent offer, If he accepted his problems with the fallen angels would be solved, He would have rias' protection and could at least have a quiet student life, something that was right now his goal. He just wanted to stop thinking about things like living or dying. He wanted to go back to his previous life as an ordinary human. If he had to ally himself with demons and become one in order to live peacefully. He will do it without doubting-, Wait a minute. Become a demon?

"W-wait a minute rias-sempai. If I accept. Will I become a demon?"

With a face of disbelief he asked that

"Yes. I will turn you into a demon if you accept"

Rias tilted her head as if she didn't understand why he was asking her that while answering with an innocent tone

"Excuse me president. But it seems that he doesn't like the idea of becoming a demon"

While akeno whispered that to rias. She looked at issei who was with eyes of disbelief

Something like becoming a demon he hadn't considered at all. If he becomes one there would be no turning back. He didn't want to leave his life as a human being. When he almost lost his mind in the loops. The only thing that kept him sane was the feeling of self. He was very attached to his humanity. He couldn't accept leaving it just for his selfish desires. Even if the fallen angels. Demons and angels want to go after him. He will never give up his humanity.

"I'm sorry rias-sempai. But right now all I have is my humanity. I can't throw it away like something disposable"

As he said that. He decided to leave the club. There was nothing more to discuss. He didn't care about the fallen angels anymore. When the time comes for them to hunt him down he will think of something

"I-issei wait. Don't you care about your life? If you don't do anything now. They could come after you today"

As rias shouted at him in disbelief. He stopped as he touched the door handle. He didn't want to die. That's the thought he had in his head. But losing the only thing he clings to was undoubtedly something worse than death. He couldn't lose his humanity.

"I'm sorry. I've made up my mind already. Don't worry about my well-being. I won't let anyone kill me"

He understood that this was a stupid idea. To pass up this opportunity just for such a silly reason. It was stupidity that could cause him many problems in the future. But he didn't care. Right now he had to think about how to deal with the fallen angels. When he finally opened the door and was about to leave. He came face to face with the student council president

"Hyoudou-kun, Didn't I tell you to come to the student council during recess? Next time I'll tell your parents how you hid in the girls' bathroom last month as punishment"

As she entered the club she said that, issei was surprised to see her, Since because of the conversation he had with rias, He had completely forgotten about her, Now that he thought about it, Did she have the same objective as rias? That's why she summoned him? He stood at the entrance not knowing what to do

"Are you going to stand there? Come here, I have to discuss something with you, Rias, From what I see you did poorly with the negotiation, I thought you would convince him"

While looking at rias with a smile she said that, issei went back in, He was no longer thinking about negotiating, so he would make it clear to both of them.

"I know what you're thinking hyoudou-kun, Don't worry, I didn't come to convince you to be my servant"

As she said that, she urged him to sit down, so he did, What did she have planned? Wait a minute. Now that he thought about it..

"Hey, I don't remember going into the girls' bathroom last month"

As issei said that. The president looked at him

"No, you didn't. Although.. Who will they believe? Just give up. Now we'll talk about something more important"

As she said that. Rias looked at her

"I must say it's a nuisance having to show this side of me. Issei doesn't want to become a demon. What do you plan to do?"

As she said that with a defeated tone. She looked at souna who had a smile

"Nothing you haven't thought of. I know you were already planning on doing this. But I'll help you watch over him in case he's in danger"

As she said that. She adjusted her glasses. Issei was a little surprised. Did she plan on taking care of him even if he refused to join her faction? That was something he didn't expect. As issei turned his gaze towards rias. She showed him a smile

"I still feel guilty that you had to deal with the fallen angel on your own. We knew she was after you. But we ignored it because we thought she just wanted to watch over you. I'm sorry"

As she apologized. Issei could only divert his gaze towards the ceiling. She certainly wasn't to blame for what happened. Although if they had warned him at least he would have died less times..No. Even if they had warned him he wouldn't have believed them. Anyway that wasn't important now

"Hyoudou-kun. About your sacred gear. Do you know how to activate it? You need a way to defend yourself. Killing a fallen angel with a light sword. Although inefficient. Was very ingenious. But it won't work again for you. They won't underestimate you next time"

As she said that she looked at issei with serious eyes. His sacred gear. His method of activation was to die and restart time a week before his death. That was the only information he had about it. No. He had a little more information but anyway he can't share it with anyone so..

"I'm sorry souna-sempai Yesterday was the first time I heard that word so I don't know how to activate it"

As he told such a clear lie rias was the next one to speak

"Activating it is simple Raise your left hand Close your eyes and visualize the most powerful image you can With that it should be enough"

As rias watched issei She gave him instructions on how to activate his sacred gear He knew nothing would happen He knew that wasn't the method of activation But it didn't matter For now he would follow her instructions The most powerful image he has That would undoubtedly be the image of that psychopath She was someone who could only kill with a lot of luck and several attempts in between If he died now There's no doubt he would die many more times to kill her again.

Thinking about that fallen angel something happened A green light illuminated the club room and his left arm was covered with a red gauntlet with claws It looked like a dragon's arm At that moment issei didn't know what was happening This What the hell was this? Could it be The physical form of his ability to go back in time?

"Twice critical I see"

While Souna whispered that, Issei looked at her surprised, did she know what it was?

"S-Souna-sempai, do you know what this is on my arm? Do you know exactly what it does?"

With disbelief, Issei asked her.

"That's your sacred gear, Hyoudou-kun. It seems like a Twice Critical. It doubles your power. Although it's common, it will undoubtedly be useful to you."

As she said that, Issei stood up abruptly. What the hell was this? If this was his sacred gear, if this was what Yuuma was after, what the hell was making him go back in time? If it wasn't a sacred gear, what was it? He didn't understand. His head started to hurt. All this time he thought his ability to come back from death was due to the supposed sacred gear that Yuuma told him about. But apparently it wasn't. Damn, if he could ask someone what the hell this power was, he would do it without a doubt. But he can't do that. After all, if he did, he would instantly wake up in his bed a week earlier.

Clarifications: If you wonder why I decided to leave him the boosted gear, it's simple, It's a crucial part of the story, I couldn't just discard it and give it to someone else, Besides there's the issue that Issei is a mere human, Even if he has the return of death he will face extremely strong people in the future, So it would be difficult to advance the story in that way, Although it's just a complement, His main ability will be the return of death.
