You call Ozpin on your scroll after going back to the school and seeing no Demons.
"Ozpin, I need Ban's location now!" You demand.
"You'll need to go to Vacuo, but that's on the other side of the continent, you can't possibly make it—."
"Call off the initiation Ozpin, with Demons roaming around its far too dangerous for the kids. Tell them anything, just give me time to at least get Ban." You plead.
"I'll do my best Meliodas." Ozpin hangs up the phone.
"Well, I have to move now, no use in holding back." You use some of your power and boost your speed to run as fast as you can to Diane.
"DIANE!" You call out. No answer.
"DIANE!!" You call out again, when you search the area, you see blood on the ground. You hear stomping and you feel the ground shaking uncontrollably.
"CAPTAIN! DEMONS ARE EVERYWHERE!"
"I know! Look, I need you to throw me and far as you can toward Vacuo."
"You want me to throw you?!?" Diane reacts the way you thought she would.
"Listen! I need to get Ban out of prison, so if you could expedite the process of getting there, that would be awesome." You explain to her.
"Oh I'm coming with!" She says getting ready to run.
"WHO IS THAT??!" You turn around and see Ruby, Weiss, Blake and Yang. All of them have their weapons drawn except Blake.
"Huntresses!" Diane yells out.
"WAIT!" You yell out, everyone stops.
"Ruby, can you guys put your weapons away?" Diane looks back at Ruby.
"So you're Summer's daughter..." She says with a saddened tone.
"You know my mom?" Ruby asks saddened as well.
"I guess there's no way to hide it now." You joke looking at Diane.
"Hmph!" Diane pouts, she then looks back to Ruby and gets sad again.
"Who are you, and what are you?" Yang asks.
"I am Diane, and I am a Giant thank you blondie!"
"Diane, that's Ruby's half-sister."
"You're Yang?"
"I'll ask again, who are you guys and how do you know us?" She gets in a defensive stance. You walk forward slowly.
"I need you three to promise me something."
"Three?" Weiss interrupts.
"Me and Blake have met before, and don't judge her for not telling you guys earlier." You pull up your sleeve and Diane turns to her right, revealing her thigh.
"My name isn't Y/n." You roll your sleeve all the way up, revealing your Dragon Mark.
Diane also turns fully, showing her Serpent Mark
The three girls look stunned.
"I am Diane, The Sin of Envy of The Seven Deadly Sins."
"And I am Meliodas, The Sin of Wrath of The Seven Deadly Sins." You and Diane tell the three girls who didn't know this.
"You're part of The Seven Deadly Sins!!!" Yang and Weiss take a step back and prepare to attack.
"Girls listen to me, I know it may sound crazy, but the reason initiation was called off wasn't due to Grimm. It's Demons. And I need to get to Vacuo to free another one of my friends, I don't want to fight you three. But if I don't get to Vacuo quickly, Beacon could crumble before the school year's even started." You say to them. They look at each other, Blake steps up.
"Meliodas isn't a criminal."
"Oh yes how could I forget, you knew this and never mentioned it?!" Weiss asks her.
"Listen to me! Meliodas saved my life the night we met, and I could feel it, he isn't a bad person. Him and the Sins were framed if I had to guess. We need to let him and Diane get to Vacuo." They look at each other, Weiss and Yang holster their weapons.
"Fine, but when you get back, we want answers." Yang says in an aggressive tone.
"Gladly-." You look at Ruby.
"Ruby?" You ask.
"How did you know Mom?" She says with her head down.
"She..." You say.
"She what?"
"She was one of us." Diane finishes. Ruby and Yang are shocked, but stay silent.
"Summer... Summer used to be The Sin of Greed before she..." You hold your tears back.
"Before she went on a mission and was killed." You let a few tears fall.
"Me and her were close... very close..." You say. You wipe your tears and look at Ruby.
"I promised her no harm would come to her children. I intend to keep that promise." She falls to her knees. You walk up and kneel beside her.
"Listen, I'll tell you all about her when we get back, but we have to go now before the Demons destroy Beacon."
"I can run there in about twenty minutes Captain." Diane tells you.
"Is that full speed?" She nods at you. You stand up and offer your hand to Ruby.
"Wh—?"
"You're already here, so you four are coming too." You say to her. You look at her sister and friends. Ruby grabs you hand, but you hold onto it.
"Diane? Catch." You throw Ruby up to Diane.
"WHAAA!!" Diane catches her with no problem.
"It's nice to meet you Ruby." Diane smiles at her.
"You three next." You hold your hand out.
"Oh no, I am not going to be thrown around like some—." You grab her by her waist and throw Weiss at Diane.
"YOU LITTLE—!" Diane catches her too. Blake offers her hand and is thrown too.
"I got it Meliodas. Thanks though." Yang puts her sunglasses on and fires into the dirt to jump into Diane's arms.
"Alright girls, hold on tight, Diane is REALLY fast!" You get ready to sprint too.
"LET'S GO!" You and Diane begin running full speed. You keep an ear open and her the four girls screaming in fear.
"AAAAAAHHHHHHHHH!!!" They scream as one.
"Thank the Deity for Blake being the middle man." You say. You pull your scroll out and call Ozpin.
"Just to let you know, Ruby, her sister, the heiress and—." You whisper into the scroll.
"The faunus are coming with me and Diane."
"Did you tell them about the Sins?" He asks.
"They took it pretty well actually, which meeeeaaannnnsss..." You say into the scroll.
"I'll will let you as you say, "whack Grimm" with my cane. But that will be after the Demons."
"Sweeeeett!! Thanks Oz, I got to go now. I'll let you know when we have Ban."
"Alright." You hang up. You and Diane keep running at full speed.
"I'm coming buddy, just be ready to kick some butt."
