"What she's getting at is, you might want to find a big tree to latch onto in case things get awry for you." Kousuke added. "What if one day your power went out of control again like with fire breath, and it actually killed someone by accident? Then, Rias can cover that up for you, maybe."
"I will, it's nothing difficult since accident can happen after all. Though it's a different story if you did it intentionally," Rias said. "Of course that comes at a certain condition, not anything like selling your soul to me, mind you. I might be a devil, but we don't do that sort of trade anymore."
"That means they may have done it in the distant past," Kousuke muttered with a whistle, then he looks away when the crimson haired girl glares at him.
"In short, I wanted to offer you a place in my peerage." After letting out a sigh, Rias finally revealed the true reason Ruri was called upon. It was like throwing a carrot to the rabbit after purposely scaring them off. It might comes off as a shrewd tactic, like a conman creating a problem out of thin air to sell their merchandises to the ignorant elderly. Except she wasn't lying at all, everything she said so far are undeniably the truth.
"Peerage?" Ruri asked, she understand the meaning of the word, yet feels as if it doesn't fit the context of the conversation at all.
"She will turn you into a reincarnated devil, which resulting in you being tied to her for the rest of your life via the Evil Piece. The latter is basically this magical chess piece that can turn anyone into a devil, pretty nifty, as expected of Ajuka, the nerd Satan. Anyway, Reincarnated Devil is basically a half-devil, so at that point you're no longer human but at the same time, you might have a durable body, which will be a great boon to you especially." Kousuke explained calmly.
"Ah, I was going to explain that! You took the words out of my mouth!"
"I don't trust you telling her everything, you might say something like 'you might feels slightly different later but it's nothing to be worried about' and be done with it." He replied with a knowing look on his face. "Being reincarnated devil might sounds good, but you also gained some negative traits, like getting damage by just mentioning God."
As if proving his words, almost everyone in the room simultaneously flinched, with the exception of him and Akeno. Ruri noticed this minute detail so she raised her brows at this, she recalled earlier on that her senior mentioned she was also a reincarnated devil. Yet she appears fine. Of course her reaction didn't escaped Kousuke's hawk-like eyes, so he continues.
"My Akeno is a little special, I tweaked her Evil Piece beforehand, thus completely sealing off most of her weaknesses for good." He admitted pompously. By now, Rias and her peerage already knew about his overpowered ability to manipulate physical laws to a certain extent thanks to his Sacred Gear.
After all, he did helped his friend out because he finds the latter rather pitiful. Between the previous Issei and Vali, one can easily tell who would dominate the battle. Though if he was pushed into the corners, there might might be some unexpected surprise. "Rather than calling it the Queen Piece, I'd like to refer it as the Empress Piece. What do you have to say to your diligent boyfriend, Your Eminence?"
"You did a fine job, my Emperor. I am very proud of you~" She replied in a jest. Her finger begins trailing under his chin, before pushing it up as she leans closer and sealed his lips with a rather passionate kiss. It was so smoothly that Ruri was stunned before her cheeks turned red from second-hand embarrassment. 'They're really bold as the rumors said...'
"Ehem! Like he said, you'll have to be reincarnated devil to join my peerage. You don't have to worry about being treat wrongfully because the Gremory are widely known for being affectionate to people we considered family, unlike the rest of the devils." Rias stated, pride swelling in her tone.
"That's low bar to begin with," Kousuke muttered after separating from his girlfriend's kissable lips with a smirk. There was a clear lipstick smudge on his lips, but he didn't rub it clean as if wanting to show it off to everyone there, especially Issei. "If you think about it from another perspective, those devils might actually be the real being made of sins, its build into their souls to literally commit sin. In that case, Rias and her entire family could be seen as weirdo or a family of freaks."
"...That's true," Ruri muttered unconsciously. As an ex human the past few days, her general knowledge of devils comes from the bible and entertainment, more specifically manga and anime, sometimes even video games. Thus. she thought his words makes a lot of sense, that's why she finds it hard to believe that becoming a devil would be anything but good. Of course if her senior is also willing to tweak her Evil Piece as well, then she might consider. However, Ruri very much knew how unlikely that sounds. They're barely acquaintance to begin with.
"Hey! Are you going to assist me in recruiting her, or stopping me from doing it?! Your words and action don't match at all!"
"I am neither, I wanted to be as neutral as possible so that she can think for herself whichever suits her best. I do think becoming a reincarnated devil is one of the good options, after all she really do needs a tough body if she didn't want things to go wrong if there are more of her dragon power still laying dormant and waiting to be awaken. The thing like that fire breathing accident might happen again, and it could result in something much worse if she is still human by then."
"There are more?!" Ruri gasped. Just the fire breathing already given her enough headache as it is. Fortunately, she was able to control it somehow thanks to her mother's teaching. But if there are more powers dwelling in her, things might really be bad for her if it manifest in a rather unlucky circumstance. Like awakening the ability to discharge electricity while inside a pool with her classmates for swimming class, that could potentially be life threatening situation, not just to her but also her friends.
"Yes, I can see it clearly. Your soul itself is slowly morphing into that of dragon, so I wouldn't be surprised if you awaken another power this week." Kousuke casually dropped the bomb while sipping on a well-brewed coffee. "Mm, the aftertaste is just addicting."
