Realizing that she was going to have to tell the truth Blaze told Rias what she wanted to hear, after all she had trusted her with the truth so it was only fair that she did the same
"Ok I'll talk, I have a sacred gear, that's why I'm so strong" Blaze admitted, revealing her strength but not how it worked or the downside that came with it
"Hey it's not a downside, it's a upgrade complained Herm able to tell what Blaze was thinking
"A sacred gear, that makes sense as to why I can't feel the energy of any other type of being on you, you're not a devil, fallen angel, angel or any other type of being from what I can tell" Rias responded, going into deep thought "what is the name of your sacred gear, maybe we I have heard of it before"
"Wait, what is the name of my sacred gear" Blaze asked Herm
"I call it 'dual nature' it shows that you can use both sides of anything, light and dark, holy and demonic and of course, it shows that you're more than just a girl" proclaims Herm proudly "also she will never have heard of it before as you are my first user as I told you so you don't need to worry about her figuring out that you have the type of dick that she probably dreams of late at night when she's alone"
"you could have just stopped after telling me she wouldn't know about it" Blaze sighed in resignation, her penis twitching due to the thoughts being put in her head "the name of my sacred gear is 'dual nature' it allows me to use opposite attributes at the same time such as fire and water and light and dark while having resistance to most elements due to it being inhabited by a goddess, it's also due to her powers influence that I'm this strong" Blaze said, not revealing anything about having reincarnated or the fact she was a futa "I'm also apparently it's first user so you won't have heard of it before"
"A sacred gear with a goddess sealed in it" replied Rias with a degree of shock forming on her face "it must be quite a powerful one, do you know the goddesses name" she inquired
"Unfortunately not, all I get when I try to think of it is something that seems to be in greek which would probably explains my physique" Blaze lied, hoping it would be enough
"Understandable, the more powerful a sacred gear the more secrets it will hold" agreed Rias, seemingly fooled by the lie "now then onto the reason I called you here, I would like to invite you to become one of us" she said, inviting Blaze
"One of you? you mean like a devil" Blaze questioned, already knowing the mechanics of the evil pieces
"Indeed, there are many benefits from doing so, the ability to fly, demonic powers which if your sacred gear does what you said it does will mean you will also most likely get angelic powers as well, a piece of my territory, an extended lifespan and a comfortable ride through life if you wish it as the Gremory family has connections everywhere and we could help you get your dream job once you have finished your eduction" Rias explained, telling Blaze the benfits of joining her
"That all sounds incredible, but what's in it for you, in the stories a deal with the devil is never without a cost" Blaze said trying to sound like this wasn't everything that she had ever dreamed, mainly due to the fact that it meant that she would get to be with Rias and Akeno everyday and she was good friends with Kiba and would get to know Koneko as well
"I won't say there's nothing in it for me" Rias smiles "having a servant as strong as you will help me in what are called rating games, a way for me to earn honor for my family, someone who is already stronger than Koneko who has been boosted by the power of the rook piece that I gave her is a rare occurence throughout all of the devils history" she explained
"Well not everyone is a reincarnated powerhouse with a goddess like me making them even stronger" exclaimed Herm proudly
"That's all well and good but I get the feeling there's something else you're not telling me, you seemed to come for me incredibly quick after finding out about me" Blaze questioned
"Hah, I guess you would find out about this soon, but I am in a need for strong servants quickly due to a situation I am being forced into" she sighed "and honestly I think with your help I would have a higher chance of being able to resolve this situation, and finding out more about your sacred gear has increased my confidence" she said determined "so will you join my group"
"I would love to help you out Rias" Blaze replied, wondering what piece she would be given
"Then let us begin the ceremony" Rias stated with a pleased smile, bringing out her evil pieces, 8 pawns, 1 rook, 1 knight and 1 bishop "let's use the rook, your power will be increased by it" the rook floating forward but nothing happening
"hrm, seems like you don't resonate with it, maybe the knight" she says taking back the rook and instead holding out the knight, but still nothing happened
"The bishop, maybe the goddesses power resonates with magical ability more" she stuttered, starting to get flustered but still nothing happened
"Please let the pawns work" she said starting to panic, but again nothing happened
"Ara ara, it seems we've underestimated Blaze here, it seems her power and potential is to much for you to change her into a devil Rias" sighed Akeno sympathetically
"No, this was supposed to be a chance for me to get out of my engagement to that scumbag Rias cried, slumping onto the floor
"I can't bear to watch this, Blaze do as I say" commanded Herm with a serious tone Blaze had never heard from her before
Following her instructions Blaze knelt down next to Rias and gently took the pawns from Rias's hand, closing her eyes and focusing on the pieces clenched in her hand, power radiating from her
"Blaze, what are you doing?" asked Rias in surprise, the rest of the group watching on in awe
A few seconds later Blaze opened her hand to show the peieces that had gone dull "this should work"
"What happened?" Rias questioned looking at the pawns drained of their powers
"The goddess inside of me informed me that although you weren't powerful enough to make me your servant she could use the power contained in these pieces as a cost to make a contract with you, essentially making it so that we are partners and due to the fact that your evil pieces were used it essentially infected me with a piece of your energy, giving off the impression that I am your servant to other people meaning that I can fight for you as your pawn in rating games while giving me access to the powers of the evil pieces as a benefit" Blaze explained
"What?" exclaimed everyone, before Rias pulled Blaze into a hug on the floor "Thank you, Thank you, you don't know what this means to me" she sobbed happily
"I-it's fine, my pleasure" stuttered Blaze, feeling Rias's soft chest pressing against her own and able to smell Rias's natural scent, her dick threatening to rip it's way out of her spats and pants all at once
"Tonights going to be fun" snickered Herm, but Blaze was to busy short circuiting from Rias's hug to be able to comprehend anything else.
