(A/n: I'm going to rough on you guys on this, but I'm not writing a backstory for Jaune Arc being betrayed, #1 I don't really care about teams Rwby & (J)PNR and anything related to beacon #2 because Samurai are better than Huntsman in almost every aspect (change my mind), and #3 Jaune after being reincarnated will have no memories of his past life, even after arriving to remnant he will have no memories about the place, (unlike the many other authors out there, who names I won't say [mostly because I poor memory of Authors names now days.].) and before anyone starts disrespecting me that there were no "Female" Samurai you would be incredibly wrong, and hey you might know them from the Fate: Grand Order series. Plus I just finished watching Godzilla: Minus One on Netflix and let's say I enjoyed watching it, it reminds myself of the original OG 1954 Godzilla movie.)

(The Dawn Empire)

[8 years before canon events happened]

As two Bokken clashed as a female samurai smiled at the young boy who was only about 10 years old, of course there was a 12 year gap between the two. Up above the training yard the Shogun Saigo Takamori watched as the two were training together.

Miyamoto Musashi a well mannered young woman with beautiful Azur blue eyes and bright pink hair, and was hearing a a sleeveless top with a deep neckline, primarily in dark tones with red accents and gold detailing, coupled with a high-waisted, red and blue skirt that has a thigh-high slit on the right side, revealing black thigh-high stockings underneath. The skirt is held by a decorative belt with intricate patterns and multiple layers, featuring a mix of red, blue, and gold. Over her top, she dons a long, flowing cape that matches her skirt in color and is similarly adorned with elaborate designs. The cape's inner lining has a leafy pattern that complements the overall motif. Her left arm is covered with a detached red sleeve that has a flared end, while her right arm remains bare, save for a black and red arm band on her upper arm. Both wrists are circled with ornate, golden bracelets.

Musashi's footwear consists of red and blue boots with a pointed, upturned toe, a design element commonly found in historical Japanese footwear. The boots have golden buckles and reach up to her knees, aligned with the overall color scheme of her outfit. But her "combatant" was a young boy, with black hair and brown eyes, he was wearing training armor similar to the traditional Samurai. Saigo knew that boy was abandoned as an infant, and was left on Saigo's front door, while a thunderstorm rumbled through the valley...

A note was left behind the note read, that the mother and her child, where on Ootojima a island close to the mainland, and was attacked by the Vikings, the defenders tried protecting as many innocent people as possible but were beginning to wipe out, that was the island's spirit appeared, and with its great vengeance attacked the Vikings without remorse, its massive dorsal plates, shaped like Mable leaves, and ripped its enemies apart... before roaring into the heavens and vanishing into a cloud of dust, like the creature never really existed. The infant eyes changed from Amber like the Black Dragon back to brown again.

Saigo never said anything about the "event" that transpired after the incident. Of course he never had too. The Emperor of the Dawn Empire forbid anyone from saying anything about it.

Saigo: どこまで行けるか見てみよう、若き赤井 (Let's see how far you go, young Akai.)

(A Decade Later)

The sound of fires raging across the Dawn Empire, as The Black Legion, the Viking clan and Dawn Empire's finest warriors rush to save as many as possible. One being a Orochi in Black & Blue, his eyes glowing amber as his Katana glowed azur blue, as a. Berserker appears welding duel axes, and tried to get the hit off him, only to be successful blocked and pushed back stunning him, as the Orochi stabbed his blade through his chest and out his back, before pulling it out, as the berserker fell dead, as a red pool formed under the corpse. As Raider with his Great Dane Axe tried his luck, the Orochi dodged the Raider's attack, and was swiftly defeated with a few powerful strikes.

Before the Orochi left his zone a strange humming noise came to his left, as he turned a black creature appeared, it looked like a Dire Wolf, but instead it looked more humanoid, it had bone spikes growing out of its back,  arms and legs, and it wolf skull and its red eyes, filled with hunger, and hate.

The Orochi stared at it with his amber eyes with flames raged in them. Orochi grabbed his Katana tightly and prepared himself for this attack, a monster, and the Black Dragon inside a human body. The beast charged first as the Orochi watched and ducked and struck drawing black blood, causing the wolf to howl in pain before turning and striking only to miss again, as Akai watched its movement like a predator watching its prey.

The beast and samurai fought through fire, ash and brimstone, until a blade went straight through the beast's skull killing it. As the beast fell and began to turn to dust. Orochi watches it disappear with concern, as he noticed the strange portal thing was still open. The Orochi carefully walked towards the portal while still holding his Katana waiting for anything to come out.

Two, three minutes passed and nothing came out, Orochi believed that it safe and almost touched when he was pulled in and disappeared from this universe, and thus began the Orochi's journey in another universe, outside of his lifestyle and way of life...
