Alright, after considering it for some time after uploading, I might do RWBY Chibi version of this fanfic when I finish the first arc of this fic (Pro. to either 6 or 7) which I'm calling the Undertale Arc, which is basically the fic's plot.

I've chosen to make Frisk 16 years old. I got a comment to make her 12 but I think 16 to 18 might be more fitting as that's around normal Ruby's age when she got into Beacon and I highly doubt Gylnda will let Ozpin let a 12 year old into Beacon, not to mention a 12 year old who will likely be bullied for a special plot twist that would actually make sense in what we know about Chara and Frisk. I'm not planning any ships with her unless platonic friendships and maybe some Frisk and Chara bromance (or whatever the female bromance is called), count as ships. Also now we've got Frisk's gender, I'm gonna call them a her and occasionally slip into gender neutral pronouns. Also Chara (who is also female) and Asriel are 16 to 18 as well.

Enjoy. Also Headcanons ahoy as they would make a lot of sense.

WARNING: This chapter contains talking about abuse and near death experiences. This chapter should be taken like a Hurt/Comfort fic for this chapter.

Frisk was at first shocked when she saw her ex-skeletal friends go heads to skull against a team of 4 that seemed professional enough to be in that school. She then got some flashbacks when S!Yang said her opening only to then swap to a quote she heard when she survived the first attack a second time. The other attacks she and P!Ruby used lead to her thinking about all her friends.

Her thoughts then drifted to the one friend she had for her entire journey (or journeys if timelines are taken into account) throughout the Underground. She was called Chara, who was like her in almost everyway, she didn't like to talk about her gender as back on the surface they both were ridiculed and bullied for being a faunues and female as they had less rights than a human girl or faunus boy. She never enjoyed disclosing her gender as some of the more sexist students msde fun of her. She then unfolded her small cat ears that blended in with her long shaggy brown hair and then a fluffy brown tail that she had wrapped around her waist like a belt made itself knowm as she then rubbed her tail, remembering all the times it was pulled.

"Frisk?" a voice said in her head as it then manifested into a girl that looks like her only with a green and yellow sweater with a notable inclusion of a golden heart locket, longer chocolate brown hair with red highlights, paler skin tone, pink blushes, and two red eyes over Frisk's brown eyes. However the most notable similarity between them is the cat ears and fluffy tail. However she could also be seen though due to her ghostly nature, but she can be seen and heard when she appears, but can only stay like it for a period of time. This was Chara's ghostly semblance, which is a special type semblance used by human and faunus spirits alike if they are fortunate enough to become a ghost. When she possessed Frisk by accident years after her death, she and Frisk gained a few benefits like talking to ghosts and seeing ghosts like even a common monster like Frogit or a boss monster like Toriel could see, Chara can also can physically maintain a form to talk to others for only 1 hour before a 10 minute cooldown occurs, She can also talk to Frisk and see enemy stats with a special move she called CHECK which can analyze any monster, human, faunus, and Grimm. However she also can be heard when she's not physical by ghosts like the mad dummy, Napstablook, Mettaton, and more. Finally her most useful ability is to heal any wounds that Frisk has that is physical over time as it did take awhile to heal damage from aguthe fall that Chara knew firsthand hurts like a Real Knife to the gut, however they require items to heal Frisk's aura. Nobody but Frisk knows that Chara exists as Chara would only hurt Toriel by bringing back memories from her death.

When Chara appeared, her eyes are full of concern, she knew Frisk was thinking about her time on the surface again. She knew Frisk wanted to talk about it, but a bully nearly strangled Frisk to death for standing up for herself and for a fellow faunus classmate a year to maybe a few years older than her. If the girl hadn't called for help, Frisk might've died for lack of oxygen. However her vocal chords were broken to the point where they couldn't be healed. However ever since Frisk woke up when her wounds from the fall were almost healed up after a few hours of being in a near death experience due to the fact she couldn't take it anymore and tried to commit suicide, Chara has been healing her vocal chords the entire time.

Frisk smiled at her friend, before they heard a knocking and a "Frisk?" as Chara vanished before Toriel could come in as Frisk hid her ears and once again wrapped the tail around her like a belt. When the goat monster came in the had a look of concern that matched Chara's. However unlike Chara, Toriel and the other monsters didn't know she was a cat faunus and was abused so much, she had a guess that was nowhere near the truth. She was only aware Chara was a faunus that fell down because she was sick of the abuse and injustice she and her fellow young faunuses got.

Toriel tried to comfort Frisk and eventually put her to sleep with a light snore coming from Frisk as the tears stopped pouring. She wondered "What happened to Frisk that could get her this upset?" Her train of thought was interrupted by a message from S!Yang that told the former queen she and P!Ruby were gonna visit them as they had a suprise for Frisk and the others.

When the 3 appeared in Snowdin as they exited Ruby's room, they didn't expect to see Frisk and their monster friends in their home.

Suddenly Ozpin rushed to bathroom on the wall next to Yang's room. When he came out, he was green and sick until he felt better a few minutes later as he was not used to it like Frisk, Yang, and Ruby were. Though they remember also feeling the urge to puke the first few times Yang used her shortcuts.

After catching everyone up on what they missed.

Ozpin then looked at the monsters before they exchanged names as Ozpin then noticed Frisk and was suprised that she was the one thst saved these creatures, he assumed she would be older or taller. He then kneeled to her eye level and said "So your the human that Miss Xiao Long told me about? I can say I'm suprised you lived a fall that would greatly lower your aura. How on Remnant did you survive it?"

Frisk felt their vocal chords were healed enough to speak, however her voice was very timid and weak as she tried to say "I don't know. Maybe I'm just lucky enough to live like the other humans who came and fell due to very certain reasons." The moment she began everyone was shocked and thought she just mute.

"Kid? How long have you've able to speak?" S!Yang asked.

"My damaged vocal chords were broken beyond repair when I was strangled and almost died by a bully when stood up for a girl, thanks to some help however, my vocal chords are slowly healing and are healed enough right now to speak very quietly."

Everymonster and the skeletal sister duo had nothing but anger and they were gonna to destroy the one who's responsible for this if they every find him. Ozpin began to stare at Frisk as he didn't know what to do.

"My child? Tell us the name of the one responsible of your pain and who you were defending? " Toriel asked as she had her motherly instincts go into overdrive.

Frisk began to cry and admit "I don't remember who they were, it was such a long time ago. I do know it was a human boy who strangled me wben I defended a faunus girl, both were either older than me or around my age when it happened.

"Why did you defend her? I'm not being racist but I want to know what you were thinking at the time." Ozpin finally asked.

"...I could relate to her in a few ways more than one and the biggest is easily explained thanks to these." Frisk said as she pointed to the cat ears and cat tail, now out in the open. Much to everyone's surprise.

Toriel finally got why Frisk was that depressed, she saw her tail looked fluffy overall, but it was thinned in certain areas like it was grabbed tightly and pulled like somebody didn't care it was attached to Frisk. She recognized Chara's tail was in a similar condition when the faunus fell down all those years ago. When Toriel was told why her tail was in such a state, the ones responsible were lucky the Barrier existed at the time and now that they're dead by now, Toriel can't exactly kill them.

Undyne and Alphys both held Frisk and they tried not to squel at how adorable Frisk looked and from the look on their faces, they were failing to not go into anime geek mode.

Asgore simply looked down at the stronger reminder of the fallen faunus that insisted on being called a human so they don't feel out of place.

Ruby then smirked as Yang told Frisk, Undyne, & Alphys about Blake and how she hid her Faunus heritage from them as well so Frisk knew she wasn't alone.

Ozpin however now felt guilty for the girl. However he had a way to make it up to her "Frisk. You showed some sort of Determination when you defended that girl did you not?"

"...yes?" She tilted her head to side in confusion.

Ruby, Summer, and Yang all knew where this was heading.

"Well I suppose you can join Miss Xiao Long and Miss Rose at Beacon Academy if it's alright?"

All of them gasped again as Frisk then stared at him for a few minutes as she then finally nodded with a "I'll do it."

As Frisk and monsters left to go pack Frisk's things, Ozpin, Yang, and Ruby stayed behind as they began to arrange Frisk's initiation at Beacon. However Yang then felt a SOUL appear in the middle of Snowdin forest and it's LV was almost though the roof at a whopping LV 67 and it was on it's way to Snowdin and possibly Frisk, and Yang knew it felt familiar from somewhere.

"Ruby, Ozpin, I felt something appear with a high amount of EXP in the forest. I'm going to go investigate it before it can harm anyone."

"EXP?" Ozpin asked.

The blonde boxer then sighed and gave a similar speech that they gave Frisk every neutral route "EXP is an acronym. It stands for 'Execution Points.' A way of quantifying the pain you have inflicted on others. When you kill someone, your EXP increases. When you have enough EXP, your LOVE increases. LOVE, too, is an acronym. It stands for 'Level of Violence.' A way of measuring someone's capacity to hurt. The more you kill, the easier it becomes to distance yourself. The more you distance yourself, the less you will hurt. The more easily you can bring yourself to hurt others."

When Yang finished, she realized something. "Somebody that feels familiar to me just appeared in a forest with an already high amount of LV... I think I know who it is. I'll be back, and with a maiden in tow if I'm right."

Before Ozpin or Ruby could interject. She was gone faster than Nora can eat 50 of Ren's pancakes.

Yang appeared in the forest as they then looked around and saw a female figure with long, messy, black, hair, as the woman's crimson red eyes glared through trees

The eyes were then met with Yang's Lilac eyes becoming the same colored crimson as the woman's eyes, only the white sclera now became a dark ominous black as her right eye also had a yellow and blue flame in it.

This was gonna be a really interesting battle.

I hoped you enjoyed.

Now many of you might be asking why I chose to make Frisk and Chara faunuses. Well according to Asriel in the endgame, Chara fell down for "not a happy reason", and then infers that Frisk might've done the same. It then clicked as faunuses were often mistreated and their backstories for this fic evolved from there.

Also if you're curious about Frisk's semblance. I have something special planned. If anyone can guess, more power to you. I also explained that Frisk, Chara, and Asriel are somewhere around 16 to 18 years old. Because it only made sense for this fic. I did get a suggestion to make her 12, but since I written the backstory by the time I read it.

Anyway I hope you're ready for the next chapter, this one's gonna be interesting and is gonna forward the plot a lot.
