Welcome to this place of random ideas. If you enjoy the idea or want to take it for yourself, PM me about it or review. If you want to take any of these ideas, please mention that you got it from me please. Anyways this whole story is just random ideas that popped into my head when I was in class or just listening to music. So enjoy the story. First up is a RWBY and Vocaloid crossover.

{play Soleil either the original version or the English version by Lizz as I added both lyrics}

A white snowy forest. In the distance, a small village partly in smoke is shown as the view shows a small circular patch in the forest. A human sized black colored bird with a white bone mask rushes through the foliage, chasing two yellow haired children, one male one female.

(Kanashii hitomi no shinigami wa kataru/God of death with a gaze of woe, spoke to me as he told me so). The boy then spins, using a short sword to deflect a peck from hitting both of them, holding the large bird back. The girl watches, scared for the boy as he is being pushed back slightly.

(Anata ga watashi o sukuu mono na no ka/ Fast, before I will lose control, please, have mercy and save my soul.) the grimm then begins to howl in pain as the sword is stabbed into its mouth. It then headbutts the young boy backwards, causing him to stumble slightly, leaving the sword stuck.

(Nozomazu ni yami o seou itami/ All the pain you feel, I am sure you didn't wish for that) "Please, help me. The pain, it hurts, it hurts so badly". The girls then looks around, wondering where the voice comes from until she makes eye contact with the large grimm.

(Kono sugata mo nanto ozomashii/ And the looks that you bear are so grim, those you wear) as the bird lets go, it flys up slightly above both of them, showing off a broken amulet imbedded in it's chest. A memory of an old friend, flashes across their minds, a blue haired man wielding a two swords, and a younger version of them placing the amulet on his neck. he then gives a small sword to the boy and pats the girl on the head before running off towards some others, all wielding some sort of weapon.

(Taiyō no yō na tatazumu shōjo wa/ shining bright, she is like the sun, waiting there for her fate to come) the girl then walks forward towards the grimm, hair glowing slightly as she walks forward.

(te o sashinoberu to eminagara kataru/ Holding out her hand with the flow, smiling as she then told you so) holding up her hand, it begins to glow a shining yellow, with the eyes of the grimm glowing the same.

(Daijōbu Yami o hikiukemashō/ "It is quite alright, I shall take the darkness that you hold") the girl then places her hand on its face while speaking, the grimm comes closer, sending the boy back with a flap of its wing.

(Sono sugata mo tori ni kaemashō/ and I will change your shape, as a bird you can escape.) holding onto the birds face and the sword, she and the bird begin to glow as she pulls the sword out. The grimm then begins to turn white while a black stigma begins to appear on the girls body.

(Sora o doko e nari to jiyū ni ikeba yoi/ You can fly to a place far away, in the sky you are free everyday) the amulet then begins glowing as the man in their memories appears from the birds chest, chains holding him to the bird. The man's eyes then open in surprise, widening as he sees the girl in front of him as he cries.

(Ate ga nai no naraba watashi to tomo ni ikō/ If you don't have a goal or a prey, then it's fine for with me you can stay) the girl then looks up, seeing the man crying over her as the boy comes closer. The chains holding him to the bird then glow before disappearing into particles. He then smiles while petting both of their heads as he too begins to glow while the grimms eyes turn golden.

(Shiroi tori wa tomo ni habataita/ white as told, wings unfold, here it stays, following always) the man then glows before he too disappears into light particles, flying into the sky as the now white grimm kneels before the girl, bowing its head to her in submission. Soon, more bird like grimm appear before them, with the large white one flying up to defend the two children with a loud screech, knocking them backwards while a large beowolf with a white rose insignia on it's chest walked towards the girl.

(Amata no yami wa sukui o matte/ many more are wanting now for her to save them all somehow) the beowolf then stares into the eyes of the girl as a voice talks to her in her head. "Please help me, I can't handle this sadness anymore" she heard with a woman's voice.

(shōjo wa subete te o sashinobete/ and the girl was reaching out, saving them without a doubt) she held out her hand, her body glowing a white with some black splotches appearing where the stigma showed. Leaning into her hand, the beowolf began turning white as the darkness went into the girl's body, the stigma growing further along. As the grimm turned white, the rose glowed as a woman appeared above the grimm, a white cape covering her black and red hair while silver eyes cried tears of joy. The chains holding her to the grimm broke as her body dispersed with a single "Thank you".

(Sora o ōitsukusu shiroi tori hikitsure/ slowly as all the birds were to fly, she was up there among in the sky) the now golden eyed white grimm then faced the group of small nevermores before howling and joining the other white grimm in defending the children by slashing the black grimm while the girl fell over collapsed as the white nevermore placed her on its back and flew up.

(fukai yoru no yō na sugata o shita shōjo/ for the birds were all covered in white, she had turned just as dark as the night) the black stigma then began spreading faster, covering most of her body turning gray while the bird protected her.

(Sude ni sono karada wa yami ni mushibamarete/ she's consumed by the darkness they bore, she shall never wake up anymore) the boy then began to jump off the smaller birds going up towards the white grimm as the girl fell off.

(tsui ni chikara tsukite tsumetaku natte iku/ for she used all the strength she would hold, now her body is finally cold) jumping higher, he began to slash some nevermores who tried to block him while using their fading bodies to jump higher.

(Nageku tori wa yami o kuraidasu/ grieving bird, gave his word, took the pain, darkness and all vain) he then caught her, glowing a dark blue while looking on in surprise as the gray glow turned back to golden while his aura changed to a grayer blue. His eyes then turned purple as two tainted black and white angel wings unfolded from his back, screaming in a rage filled fury as he started to fly.

(Sora o ōitsukusu kuroi tori no naka de/ through the clouds up he would fly, birds in black were all over the sky) as he went up, the white Grimm began to help him attack the black Grimm as he began slashing everything except the girl.

(konjiki ni kagayaku kimi no na wa Soreiyu/ now you shine like the gold on the sea, all because you are Soleil) as he past the cloud line, all the black nevermores flew away while the once black wings turned white. He then felt a sense of calm overcome him as the wings went away in a cloud of feathers. Looking at the girls face, he then smiled as he fell unconscious while the white bird grimm caught them and landed safely on the ground. As it landed, it gently placed them on a patch of flowers while both white Grimm laid next to the two, protecting them from the cold.

A/N so what did you think. If you liked it then hopefully you may review. I may start a story for this as with the other ideas that I may put on here. If you want to take a story then please PM me first so that I may read your story when you post it.

Anyways the main idea is that when a human or faunus die to grimm, their soul is overcome by the negative emotion that comes across them or that they last felt turning them into the species of grimm that killed them. Hunters and huntresses who die and turn into grimm are stronger and smarter then other grimm and hold their emblem on their body, whether it be on their fur or their bone armor. If normal hunters and huntresses kill these human grimm, their souls will just be reborn as another grimm until their tenth death causing them to pass on with the pains of all their deaths as grimm in memory. The vocaloid main characters are going to be Kagamine Rin and Len, Hatsune Miku, and Gumi. Each will have their own semblance and will be put on the same team. Rin and Len will still be fourteen but will be twins in this story allowing a closer bond between them.

Rin's emblem is a golden butterfly on her right shoulder, (get the reference) and she has a semblance allowing her to purify the spirits of humans who have died to grimm and only the human spirits. The darkness she absorbs leaves her body slowly but she can die or go into a coma if too much darkness is in her. The purified grimm then turn into familiar like beings focused on protecting Rin and following her orders. She uses a large staff loaded with wind dust as her weapon.

Len's emblem is the sun from the soleil title and he has the power to take the darkness Rin has absorbed, using his semblance to change the darkness to light using wings while in a rage focused on protecting Rin if too much darkness is taken into him or Rin. If Rin is forced into a coma by darkness, Len can absorb the darkness, making the coma into a nights rest while going into a rampage. If there is not much darkness, he won't be overcome with rage. He uses a short sword like in the music video.

Miku will have the semblance Chibification, allowing her to make partly sentient chibis and her emblem will stay her 01 on her arm. They can be whoever miku deems a friend and follow a rpg like system with a health system showing how much aura they have left in them. The chibi follow a rpg like system with the classes as well such as sword master and gunslinger. Along with following an rpg system, they can heal if by eating and drinking allowing them to last longer. If the chibi is given aura from the one they are based after, they will gain some of their personality. If a chibi dies, miku can resummon them with the sufficient aura. Summoning the chibi only take some aura and doesn't continuously spend her aura allowing them to roam freely. Miku uses a headset to send music to attack enemies along with her chibis. She can only have one chibi of any person and the chibi's have their own language that only themselves and miku can understand.

Gumi is based of the song panda hero and her emblem is a panda face. Her semblance is called Deep Pockets which lets her take anything out of anywhere. She can pull a baseball bat from behind her back and even a nuke from a trash can. Anything she pulls out will disappear after a minute of her not being in contact with it. She uses anything and everything as a weapon as her semblance allows anything and anything to be pulled out should she need it. She needs a large rocket launcher, she can pull it out of her pockets or even a hole. If she can fit her hand in it, she can pull anything out of it.
