Demon Mentor (Akaza Reader X RWBY)

Akaza, Third Upper Demon

A/n: Something different that peaked my interests.

-Ruby and Yang in Forever Fall Forest-
Ruby was going to get sap from the Forever Fall Forest to make some sweets for her team. She was made the team leader so she believed she should do something nice to build morale. Weiss being on the team was not a huge help either but she was sure she could win them over with her mother's famous crimson pancakes. Yang had tagged along as to not let her sister go off on her own. The forest is pretty safe all things considered and Ruby is very capable but Yang still worries, she is her baby sister after all. Ruby was also doing this in hopes after were assigned a mentor they would recognize her attempts to bring the team together. At the moment team JNPR had their mentor and his name was Kyojuro Rengoku, Ruby thought that he was really cool. Though they hadn't seen him fight or anything like that but the look he has as well as his demeanor just puts off that he has considerable strength. Ruby then decides to say enthusiastically Yang.
Ruby:"I sure hope we learn who our mentor is going to be soon. I hope they are super strong and cool!"
Yang:"I just hope they are just as big a hunk as Team JNPR's."
Ruby:"Ew!! Yang he's only a little younger than our dad!"
Yang:"I'm just saying hopefully his hair isn't the only thing fiery about him."
Ruby:"Every time I talk to you make me want to scrub my brain!"
Yang:"Aww! Does baby sister not have a crush? I'm sure some guy at the school has caught your eyes. I bet it's that guy blonde hair and blue ey-..."
They just hear a loud concussive boom ring out through all the woods at this Ruby begins running over to the direction of the sound. Upon arriving Ruby's eyes widen in horror as she stares at the crater, Yang soon arrives and is very confused until she lays eyes on what is sitting there smiling at the two huntresses in training.

(This is you, though for a bit your gonna be called Akaza. Your full name is (Y/n) Akaza, but for reasons you'll see later he doesn't use that name)
Akaza:"Two huntresses in the Forever Fall Forest? By themselves? That's very peculiar. Anyhow why don't you show me how strong you are."
Ruby blinked and in that time he had closed the distance and hit Yang who had blocked causing an awkward metal clang to ring out while sending her flying into the woods. At this Ruby ran off using her semblance to get away. She turns around to see where the demon was but slammed into someone and upon looking up she began to tremble in fear. Her whole life flashed before her eyes as she began to tear up, she expected a monstrous punch to split her head but instead she feels her hood be pulled off her head. She finally musters the feeling to look him in his eyes, she then gets a flash of memories, but not hers. She looks at him in shock until he says.
Akaza:"They train you huntresses younger and younger it feels. You must be Summer's child, the eyes are kind of a dead giveaway."
Ruby can tell he has no ill will for her, in fact she almost feels like he has her best interests in mind she then sees Yang throwing a punch at him. Only for him to grab her fist and slamming her into the ground before deciding to knock Ruby out.
-Team RWBY's Dorm-
Ruby jerks awake in her bed as she looks around in fear only to see her room was normal. She soon hears a knock and opens the door to see Headmaster Ozpin. Causing Ruby to shake off her grogginess and say.
Ruby:"Oh hello Mr. Ozpin."
Ozpin:"Good Evening, Miss Rose I came by to tell you that your team will be receiving your mentor tomorrow."
Ruby:"Oh that's great. Who is it?"
-Earlier-
Akaza:"I brought back your two huntresses. You will not get another act of kindness from me."
Ozpin:"And why did I receive it this time. You're an upper rank demon I don't think whoever you receive orders from would be pleased. You should be trying to rip my head off or painted the dorms with all my children's blood that reside there. But you returned two kids without any carnage. Why?"
Akaza:"Maybe I hope they'll get better and I'll have a proper fight. Also killing you is not so simple we both know that."
Akaza starts to walk away only for Ozpin to say.
Ozpin:"I want you to be a mentor to team of hunters here."
Akaza:"And why the hell would I want to do that?"
Ozpin:"Because she wanted you to be better."
Akaza stops as he sees a flash of a woman with blue eyes and white hair giving him a smile before changing to a woman that looks just like Ruby but with a white cloak and a few months pregnant. At this Akaza stops before punching the wall sending a large crack up the wall.

A/n: Wanted to do something involving demon slayer as after Mugen Train I finished the manga and I loved it. I hope you guys will like it. Oh also Which team RWBY mother should be close to Akaza? Answers should be placed in the comments. Until next time peace!
