Tai just walks in the house, defeated after he tried to search for his missing daughters. He started his search since they disappeared. He was devastated when he returned from the killing spree of Grimm around the house, but when he returned and saw none of his girls at the house, he started to panic.

He searched for hours and hours, but he couldn't find them anywhere. When he was searching, he started to remember all the terrible things he did to them. The neglect, the abuse, the beatings he gave out, the bullshit punishments he gave to them, the slavery he forced them.

When he entered his house, his regret went to even further when he saw Yang's arm in the middle of the room. When he saw the arm, it was the last straw. Tears started to form as more regret started to take over his mind. He makes his way towards the kitchen, trying to look for any knife that could do the work. But he felt that he wasn't alone in the house.

"How could you?" said a female voice behind Tai.

He turns around, and what shocked by who he see in one of the chairs in the living room. A white-cloaked figure, dressed in a black dress, and her hair, black with red tips, and her eyes covered by a blindfold.

"S-Summer?" he asked, in disbelieve.

"I'm surprised you still remember me. I'll ask again. How could you? How could you do that to your own daughters!?" she asked, slowly getting angry.

"Summer list-"

"NO, YOU LISTEN! You used your own daughters as slaves! You abused them! YOU CUT YANG'S ARM OFF!" Summer screamed as she her voice slowly started to get distorted.

"Summer, please. Listen out," Tai said, slowly started to shake in fear.

"Listen out? LISTEN OUT!? WHAT IS THERE TO LISTEN TO!?" she screamed in rage.

Her body started to make disturbing twisting sounds.

"NOW I UNDERSTAND WHY RAVEN LEFT YOU! BECUASE YOU'RE A MONSTER TO YOUR OWN FAMILY!"

Summer's arm started to break and twist in disturbing ways under her cloak. Tai started to take a step backwards as he continued to watch Summer in fear.

"I'M GLAD THAT THEY ARE SAFE NOW, AWAY FROM YOU! BECAUSE I WON'T FEEL ANY REGRET FOR WHAT I'M ABOUT TO DO TO YOU!" she screamed as she continued to transform.

Her hair started to turn into a dirty yellow colour, her arm started to bend backward and her left hand started to crack, twist and bend in unnatural ways. Then her hand started to take shape of an axe as the skin started to harden and turn metallic.

Next, was her face. She ripped the blindfold off, revealing her missing eyes as the skin around her mouth to dissolve and rot away, revealing a set of long, sharp set of teeth. What's more terrifying is that there were multiple layers of teeth. Then, the dissolving skin started to travel further down her face and then down to her neck as more teeth started to form all the way down to the neck.

All the while, her cloths started to change, from her white hooded cloak to a black, tattered cloak and her black dress turned into the same clothes that Tai was wearing, but very worn down, ripped and blooded.

When the transformation was done, Tai was shaking in fear, on the ground and shaking in fear. Summer, or what was once her, started to slowly approach him and raise the axe hand.

"You'Ve hURt mY LitTLe giRlS, so NOw... I'm goInG To hUrt YOU!" said Summer, bringing the axe above her head.

With one powerful swing, Summer brought the axe down and started to cut Tai's arm off. The first swing stopped when the axe hit the bone. She pulls the axe back and swung down on the arm again and again, all the while Tai was screaming from the top of his lungs. Once the arm has come off, Tai was crying in pure pain.

"How does it feel, knowing that you did the same thing to your own daughter?" said Summer, grabbing the arm.

Tai didn't answer, he just tried to hold the stub that was once his arm an continued to cry. Summer just scoffed at him.

"Just know, Taiyang, I will never forgive you what you've done to Ruby and Yang," she said as she leaves the place that was once her home.

As Summer left the home, she slowly started to transform back into her original form.

-Emerald Forest, Near Beacon-

I was making my way back to Vale, but taking quite a detour to avoided from anyone seeing me. While I was slowly nearing it little campsite that Tenzu and I agreed on, I only kept worrying about Yang, if she's going to be alright.

He explained that this ritual needed a body part from someone else, so that one of his 'demons' can do a fair trade. Oum knows what might happen, but... in all honestly, it felt good, cutting Tai's arm off. Especially after what he did to my little girls.

After a while, I found the meet up point where Tenzu and I agreed on, but I was surprised to see Qrow there as well.

"Hey Summer," said Qrow, with a sleeping Yang in her arms.

"Where's Ruby?" I asked in a worried tone.

"Don't worry, she's with Glynda. Tenzu told me what the two of you were planning," Qrow explained.

I gave a glare to Tenzu, not that he would be able to see it.

"Do you have it?" Tenzu asked in a serious tone.

"I do," I responded as I handed him the arm.

"Great, then, the ritual can begin," said Tenzu as he grabs the arm and goes to an altar.

He goes to the makeshift altar made of stone, pebbles and all of them with special markings on it. He created for this demon and put the arm on it.

"Undertaker, I summon you," Tenzu commanded as his blind eye started to glow a gentle red colour.

Suddenly, the markings on the rocks started to glow the same way as his eye does. Then, some sort of portal started to appear in front of the altar and Tenzu. The portal itself was a mixture of red and black. Moments later, some sort of demon started to come through it. As far as I can see from the silhouette, it was as big as an Ursa and maybe has the muscles for it. But there was this malevolent aura around it.

"Ah, Tenzu Shiki. It has been a while since you last summoned me. Now, what's could be the reason you've summoned me?" said the demon.

"I came to make a bargain," said Tenzu in a serious tone.

"I see. For who is this arm for, if I may ask?" said Undertaker.

"It's for her," said Tenzu as he gestured towards the sleeping Yang in Qrow's arms.

"Alright. If I may ask, what happened to her?" said the demon in a curious tone.

"Abusive father. Cut her arm off to show a 'lesson' as he put it," Qrow explained.

"Alright. Tenzu, can you hand me the arm, please?" the demon asked.

Tenzu grabs the arm, and kneels in towards Undertaker, presenting him the arm. The demon takes the arm, with one hand and let it disintegrate it.

"Please, bring the child closer to me," said the demon.

Qrow looks a bit worried towards me, but I trusted Tenzu. So I nodded towards Qrow. He then started to walks towards the demon. Once Qrow was close enough to the demon, Undertaker places his hand above Yang and a dark red aura started to form in his hand.

Suddenly, Yang's missing arm started to create a silhouette of dark red. The bones of her arm started to grow, along with the muscles around it. The arm started to grow normally, until it started to develop the skin. And yellow glowing skin started to form first. Then, a second layer skin started to form and this one was thicker and black. Once process was done, Undertaker removed his hand.

(A/N: I know, it looks terrible. But it's the best I could do in a short period of time.)

"She'll be able to transform her arm into a normal looking arm. But this form will return when she'll use her semblance," the demon explained.

"Thank you, Undertaker, for your help," said Tenzu.

"The pleasure was all mine, Tenzu Shiki. May our path meet in the future," said the demon as he disappeared in his portal.

When the demon was officially gone, I quickly hugged Tenzu. He was surprised at first, but quickly hugged me back.

"Thank you so much, Tenzu. You have no idea how grateful I am," I said to him.

"I have to agree as well. If there is anyway I could repay you, just say," said Qrow.

"I was just glad to help your family. You guys own me nothing, no go own and go back to your dorms. I'm sure Ruby is very worried about you," he said with a kind smile.

"Again, thank you so much, Tenzu," I said as I gave him one final hug before Qrow and I make our way back to Beacon.

"May our way cross in the future," said Qrow.

"I'm sure they will," said Tenzu as he makes his way deeper in the forest.
