(AN: The rating games is gonna be different from what was shown in the anime. Take it as a butterfly effect)
=========
William and co. are currently waiting inside a room. Today is the rating games against Raiser.
"I wonder how did you do that William. I can feel your part of my peerage but not fully part of it" Rias asked curiously.
"I have my secrets~" He didn't answer and just smile. What Rias was talking about was William being a temporary part of her peerage. Of course along with Asia.
How he did that was, of course browsing the shop and see if an item can help him. And there is, so he borrowed 1 bishop piece and a pawn piece.
He then bought 2 of said item priced cheaply at 20 points each. He the. used the item and made so that the evil pieces made them into temporary part of the peerage. It's duration is 2 days.
They waited and soon they were teleported to a separate space. The model was kuoh academy and they were at ORC.
[Ladies and Gentlemen, today we are gonna witness the fight between Raiser-sama against Rias-sama]
[If Raiser-sama lose this match then the engagement between them will be nullified. But if Rias-sama lose then they will be married tomorrow. Now let the match begin!!]
"Just stay here and watch me." William said before jumping down. He ran towards the field and met Raiser and his whole peerage.
He wore his usual shirt with hoodie to hide his hair. And he also wore a his silver masked to hide his face.
"Is Rias surrendering by sending only you?" Raiser mocked after seeing William.
"Hey Fir- I mean Raiser want a personal bet with me?" William smiled playfully.
"Hmm? Why should I bet with you commoner?!"
William took out a demonic sword he created using his magic. Dense demonic energy filled the field.
"If you win I'll give you this, and if you loseI will take your sister with me"
Raiser's eyes was full of greed when he saw the demonic sword. Though he can't use it in battle, he can use it to boast to other.
"I agree, hahaha that sword will be mine" Yup he immediately Agreed.
"Nii-sama?!" Ravel was shocked hearing her brother sold her out quickly due to greed. She smiled wrly and shook her head.
"Alright then..." William kept the demonic sword away and took out his personal sword. He didn't even wait and slashed his sword.
A crescent blade made of light was unleashed towards his opponent.
'Booommmm!'
Dust filled the air, William just used a casual attack so some devils survived. He doesn't plan on showing his full power here, maybe...
Before the opponent can even react he appeared in front of them.
"Wha-?!" Before they can finished what their saying William already started cutting them down. Few moments later, the dust already subsided.
Raiser is the only one left and he was bounded by golden chains, Enkidu the chains of heaven.
"Now then I heard you are immortal because of the pheonix blood in you, is that right?" William asked playfully.
"That's right commoner"
"Well then let me try that immortality thing of yours" He then created Harpe the immortal slaying scythe. Raiser can feel danger when he saw Harpe.
William then cut off one of Raiser's arm. But it didn't regenerate.
"Aahhhh" Raiser screamed
"Hm...I guess you don't have immortality after all. If you had then shouldn't that already regenerated?"
("Partner, what is that scythe?")
"Hmm? It's Harpe the immortal slaying scythe Why?"
"Well since I've already tested that Harpe works then you can die now." After saying so he beheaded Raiser with harpe.
Silence...
Those watching was silent. The match only took a few minutes and it already ended. In fact it only dragged on because of the taunting part. Whereas the real fight was only seconds. And more importantly the one who fought was only one person.
"Heyy! What are you waiting for, the fight is done"
[Uhm, a-and the winner of this rating game is Rias-sama!]
==========
The next day, in the ORC William sat in a sofa while opposite to him is Ravel. Rias is beside him while Akeno served tea.
"So? You're here because of the bet?" Rias asked Ravel who was blushing hard after seeing William's face.
"Y-yes Rias-sama, so may I ask where is that man who made the bet?" She said while glancing at William who just smiled.
"Here he is" Rias said pointing at William.
"Nice to meet you ms. Phenex, my name is William Arkwright. About the bet you don't have to worry, I just did that so you can get out of Raiser's peerage." William started explaining.
"Thats-...Thank you but as a noble I must fulfill the bet. Especially since it was in an official rating games." Ravel stated with conviction but her blushing face ruined it.
"Heeeh...Is that really the reason?" Rias teased
"Okay okay, then I accept"
"Thank you William-sama"
