Katekyo Hitman Reborn x RWBY

Note: Its actually a different weave to Slytherin Stolen Princess.

Airhead. Oblivious.

Those were the words that completely describe Nana Sawada.

Well, it really fits to the T.

Nana is a lovely Japanese brown haired woman who is the female version of her son Tsunayoshi Sawada. Being married to Iemitsu Sawada, the blonde Italian she loves so much.

To an outsider, she is a perfect wife fully dependent on her husband and doting son. However, once you know what to look, the picture perfect family she is painting at is not that perfect.

Because her darling of a husband is never home. Yes, Iemitsu is loading their account with money so she and her Tsu-kun could live without needing to work. Contented being a housewife that took care of the house, feed her son and all the normal things to do.

Obliviousness. . . along of being an airhead is actually damaging her son's life. She notice the wounds of her baby boy but always chalks it out being her Tsu-kun being extra clumsy.

To be honest, this is not normal. A voice in her head always screams how outrageous is she doing. Being trap on her own delusion of a perfect family is very much a problem.

Even so, Tsunayoshi loves his mother dearly. Of course, he noticed that his mother is not always there but having her in his side is a blessing unlike his most likely dead father.

Nana argued that Iemitsu is still alive, anyway.

Not that he would believe that a Drifter that would spend a week on their house every few years is his Father. No way, thank you!

How could he convince his mother that she needs to get married?! His father is dead, damn it!

Their normal lives took a deep turn when Nana found a pamphlet about home tutors. Of course, Tsuna is suspicious since the said Tutor appeared immediately just before he goes to school.

The baby in suit, the Sun Arcobaleno Reborn told him he is the next Vongola Decimo, the leader of the most bloodiest Mafia organization.

Breaking down inside his head, Dame Tsuna analyzed his options. Reborn told him that he is the last heir so in other words, he had no escape. Also, the information network Reborn has, he could easily search for his father and maybe, just maybe , they could see what the heck is wrong with his mother.

"Okay, just help me with Kaasan. I want to know what is wrong with her."

"Dame Tsuna, explain."

And explain he did.

Reborn agreed to help him as the Sun Arcobaleno wanted this tutoring much easier. Tsuna may be a Dame according to his information given by CEDEF, he is actually seeing the while picture.

And he doesn't like what he saw.

Nana is still oblivious on what is happening around her but notice the growing number of Tsu-kun's friends. She is very happy about it as his grades are raising spectacularly!

Oohh, she should call Papa about this!

When that thought came, it made her halt on the middle of the street. Something is very wrong that it triggered something buried underneath her consciousness.

Nana didn't noticed the incoming ten wheeler truck that came out of nowhere.

The said vehicle slammed on her sending her flying. Her body hit a thick lamp post.

She could hear the bones cracking as her skin turned cold.

The last thing on her mind is that her Tsu-kun would be sad.

***********""

Blake Belladonna hated her life.

Being a Faunus, she is automatically a second class citizen that made her hide her cat ears with a black bow. She thought her group, the White Fang, could be treated as normal people.

She was wrong.

People lashes out to the things they cannot understand. Well, Ruby, Weiss and Yang, along the Team JNPR, accepted who she is but honestly? She's really irritated on normal humans who treated her race like a gum in their shoe.

Being a Huntress is such a great opportunity to stop Adam and Salem, well, Adam since Salem killed her.

Wait, Salem did kill her right? Then why in the dust name is she feeling like crap?

Opening her eyes, she wince at the lighting. Hearing a rustle of clothes, the lights dimmed as she smelled the antiseptics around.

She's in the hospital?

"Kaasan, how are you feeling?"

Golden eyes met caramel brown.

"T-Tsu-kun. . .?" She whispered.

How the hell she knew this boy?!

Tsunayoshi grabbed a glass of cold water and helped her drink it. Taking small sips until she is full, Blake leaned on the pillows on her back.

"Kaasan, I'm glad your are awake! You scared me.. . " the young man gently wrapped his arms loosely on her waist as he buried his head on her bust.

"I'm. . . sorry," her eyes immediately landed on the flower portrait in front of her bed. "Get out, whoever you are."

If the baby in disguised is startled, he didn't show it. Something , also something is rubbing her aura in the wrong way that she wanted to wield Gambol Shroud and cut it (not the baby) into half and burn it on fire.

"Please remove that thing or I might destroy it."

"Ciassou, Mama. I do not know what you are talking to."

Blake narrow her golden eyes that resembles a cat.

"The pacifier. That thing is filled with darkness much worse of a Grimm. I don't think you are oblivious to not notice its feeding your aura."

"Its called Arcobaleno curse, Kaasan." Tsuna looked on her face. "You should never hide your eyes. They are lovely"

"Hmm, I never hide them except for my ears. . ." Blake looked around for a mirror which magically appeared beside her.

Looking on her reflection,

"What in the name of the Four Maidens happened to my hair?"
Her once bouncy and wavy black hair that reach her waist is now neck length. "Augh, I need to ask Weiss for this. . ."

Tsuna tilted his head cutely.

"Mom, whose Weiss?"

"She's my friend. One of them. Weiss Schnee is the heiress of Schnee Conglomerate." Blake run her fingers on her sons fluffy hair. "Now, care to tell me why I had two sets of memories? They are a still a bit fuzzy so~"

The Decimo heir told her what happened this past fourteen years, what he knew anyway. Tsuna didn't want to hide anything even Reborn disagree on telling Blake some parts.

Like the Flames.

"So, my idiot of a husband decided its a great idea to seal MY five year old flame active son, turning him into a clumsy and bullied teen. While my Nana persona is such an embarrassment of a parent." Blake shook her head in disbelief. Hugging her son, "I'm so sorry, Tsu-kun. My own mother would be horrified knowing this."

Tsuna shook his head. "No, it's not your fault being affected by Sky Infection."

"That's not an excuse. My aura should had protected me!" Her cat ears lay flat on her head. "I'm so sorry. Please let me make up those years. . ."

He just nodded.

*********
Blake finally got discharge of the Hospital. Sure, she shocked the kids of her new look but really, she missed her house.

"Mom, what are your plans if papa comes home?" Tsuna asked as they settled on the car Reborn rented.

"My, Tsu-kun, have Gambol Shroud after that imbecile son of the bitch." She answered as she played with her bracelet that her son only noticed after the incident. "Also, I am a Faunus, dear. And according to Dr. Shamal, I am a Misty Rain so don't worry."

Tsuna smiled as he buried himself upon his mother. Since then, Blake is very much affectionate which he doesn't mind.

He ignored Reborn teasing him as a Mamma's boy.

Which us actually true, but who cares?

Reaching their house, Iemitsu Sawada spit his sake.

His former brown haired wife is now an exotic, and drop dead gorgeous raven haired, golden eyed woman who is wearing a white fitted blouse, black slacks that fit her lovely lower half like a glove partnered by violet thigh high heeled boots. A black bow is tied on her neck and hair.

Those cat like golden eyes studied him like a predator who was about yo play with her prey.

"So, you are Iemitsu, my. . . husband." Tsuna smirked hearing his beloved mother spit the title with so much venom. Producing a large tub of popcorn, he sat down beside Reborn and Hibari of all people, enjoying the drama.

"Nana, dear. . ."

A sharp sound Pierce their ears as her black bracelet transformed into a thick cleaver type weapon pointed on the blonde's neck.

"My name is Blake Belladonna. A Faunus and a Huntress. I am never be Nana Sawada, a airhead that is a poor excuse of a mother. I am still muffled on how I came in this world from Remnant but beside the point, I want divorce and full custody of my son."

Iemitsu gulped as the sheat of Gambol Shroud drew blood on his cheek. He tried flairing his sky but the result is. . .

"How ungraceful."

The once flourish living room turned into rubble as two clones of Blake appeared. Her weapon is coated with violet and blue flames. Golden eyes are filled with amusement as she unsheated Gambol Shroud.

"He's all yours, Mama." Tsuna stood up and drag both Hibari and Reborn.

"Thank you, Dear. I meet me in Takeshusi."

"You are allowing her to kill your Father?" Reborn asked as they gotten out of the door.

Amber golden eyes stared at his dark ones.

"That man is not my father. Its always been my Mother and I. Also, he had it coming after sealing an active Sky.''
