They immediately changed their civilian clothes to hero clothes thanks to Zatanna's magic. None of them are expecting someone is going to ruin their play and the girls knew the intruder is.

"Celestial, do you know who that crazy chic is?" Kid Flash asked the scarlet-haired girl curiously.

"Yes, in fact-"

"Covering your identity so no one would know who you are, Rubina Hart." She froze and stared at the person in front of them. "It's actually pointless since I knew you girls are."

"David..." Ruby whispered at the person's name. "Is that actually your real name or fake?" She questioned the blond boy.

David stares at her with hatred and scowling look. "You took something from me and I intend to take it."

"You're part of the Mendez Clan." Robin is starting to realize how Ruby's crystal reacts whenever he's close to her.

David claps his hand with a mocking look. "Bravo, what if I am? That pesky brat is not a Mendez and she obtained it from someone else. Tell me, little girl... how did you obtain them? Slaughtering my people? Well, I can't blame you since-"

"I never killed anyone at all!" Ruby defended herself and glaring at the blond red-eyed man in front of her. "Lola gave me this power so I'll survive."

"Lola?" He hums in amusement and tapping his chin. "Ohh!" David snaps his finger. "That old hag? I didn't know she was alive until died in tragic by your arms."

"Don't talk to Lola that way..." Ruby growled in anger and hating someone to mock her mother figure's death. "She died as a hero and I'm not letting anyone mocking her death!"

He glared at the scarlet-haired girl. "You never deserve to wield Crystal magic and you must die, Rubina Hart!"

Kitsune and Aqualad dodge Lust's whips to avoid getting hit. The iris blue-haired smirked and licks the handle of her whip. "You guys are good at dodging." She complimented them but they didn't take it by heart.

"Why are you here, Lust?" Kitsune asked her coldly. She never knows someone from Earthland would come here to find them.

Lust is wearing a black, one-piece bodysuit with high heels and traces of magenta on the legs, torso, and arms which is also accompanied by a set of matching earrings and a choker. "Simple, I want to end your life."

"You're still upset my friends and I defeated your guild." Aaliyah commented bluntly. She tore the skirt of her gown to reveal black cycling shots as she would be able to move freely.

"Grimoire Heart may disband but I'm on my own." Lust smirked darky to see her darken expression. "Aww, don't make that pouty face... It makes me want to torment you more..."

"You really are sadist, Lust." Kitsune and glanced at Aqualad. "Go join the others, I'll deal with Lust."

"I can't leave you alone to fight her, Kitsune." Aqualad denied the idea of her leaving Lust alone.

"Aqualad, it's not the time for debate- look out!" Kitsune immediately casts a water sphere for the incoming attack. "Lust is out of your league! Believe me, when I say this, this girl is their secret eight Queen of Purgatory, Lust Cozbi."

Lust smiles in amusement. "You've done your homework, Ms Empress of the Oceans and Seas. I don't even know why you manage to be part of the Ten Wizards Saints." She noticed the Atlantean's bewildered expression. "Oh? He doesn't even know you're a powerful wizard and holding back a lot of poten-"

"U~ōtādoragon: Tetsu no ken! (Water Dragon: Iron fist!)" Lust barely dodges her surprised attack and grazes her left cheek.

"Nice try, blondie. Take this, Jaakuna kage! (Evil shadows!)" Shadows comes out from Lust's body as it tried to capture her.

"Kitsune!" Aqualad summons his water and stricks the shadow with lightning.

"Baka! (Idiot!)" Kitsune snapped as the shadow changed it course to attack Aqualad. "Are you asking for a death wish, you, fish brain! U~ōtādoragon: Safaiajetto! (Water dragon: Sapphire jet!)" Her whole body covered in water and attacking towards Lust.

Lust smirked and disappeared to appear behind Aaliyah. "Not fast enough to beat me, blondie." She finally wrapped Aaliyah using her whip and slams the blonde girl. "Still the same, Aaliyah."

"Kitsune!" Aqualad cried out her name and dodges from the shadows. It's hard for him to dodge the shadows, especially he doesn't have the ability to create a light to make it disappeared.

"Seinaru ken! (Holy light sword!)" A light of sword heading towards the shadows as it screamed in pain and disappeared. "I'm in the right time to help you guys out."

"Saber!" Aqualad is relieved to see his friend again. "Glad you can join us."

Saber stands in front of Aqualad to see Kitsune still wearing a torn wedding gown is fighting Lust. "Angel told me basic things about Lust. I came here as soon as I could to help you guys out." He explained and feels worried about Kitsune's well-being.

"The civilians?" Aqualad asked Saber curiously.

"All of them are out safely. Zatanna, Artemis, Superboy, Red Arrow, Angel and Miss Martian are with them." Saber explained and dodges from the shadows. "Angel wasn't kidding these shadows are not easy to be taken down easily." He smiled in amusement and summon his swords. "Let Kitsune handle Lust whereas we deal with shadows."

Celestial backflips and raising her hand. "Kurisutarumeiku: Daiyamondoshawā! (Crystal make: Diamond shower!)" David dodges thousands of shards heading towards their direction.

The blond red-eyed boy trapped the boy wonder and yellow speedster inside of the crystal sphere. He wanted the scarlet-haired girl to have a showdown in order to obtain the last final crystal magic. The boys tried their best to break the spell but it's futile for them to shatter it into pieces without harming themselves.

"Why can't Celestial summoned her spirits?" Kid Flash asked the boy wonder curiously while banging the crystal. "Darn it, it won't budge!"

"Celestial and I read the book together from Lola saying she can only use crystal magic when someone dares to challenge another crystal user." Robin answered with a solemn look on his face. "In her case, she needs to win this match unless he can make the choice."

Wally's eyes widened in shock. He finally understands why Celestial didn't use her crystal magic. "You mean-"

"Yeah, she needs to win this, or we might lose her forever." Robin answered with a grim look on his face. He lost his family from the tragic and Robin couldn't stand of losing someone he cares for again. They just finally express their love with each other and found someone who can deal with his impulsiveness.

"Too slow!" David showed up behind her. "Kurisutarumeiku: Ransu! (Crystal make: Lance!)" He summons his lance and about to stab Celestial.

"I won't lose! Kurisutarumeiku: Futaken! (Crystal make: Dual sword!)" She summons two swords and deflects his attack. "Why? Do you want to kill me so badly, David?"

"You don't deserve it or anyone from the Mendez Clan!" David grinned with a sadist look on his face. "I should be the one to wield the crystals and no one can get in my way even from the likes of you! Kurisutarumeiku: Borutekkusu! (Crystal make: Vortex!)"

"Kurisutarumeiku: Dōmu! (Crystal make: Dome!)" She immediately creates a dome to protect herself from the crystals. "What Lola said it's true... the Mendez Clan are-"

"No more but only myself and you scum!" He grinned madly and Celestial only glared. "Die!"

"I may not deserve obtaining this crystal to give me a second chance to live." Celestial gritted her teeth angrily and eyes glowed. "You killed your clan and that's unacceptable! Kurisutarumeiku: Sū sen no hahen (Crystal make: Thousands of shards!)" Summoning the shards towards his direction.

David covers his face. "Kurisutarumeiku: Teikuōbā(Crystal make: Takeover!)" His whole body covered in crimson crystals.

"No way..." Celestial is staring at him with a surprised look on her face. "You achieved takeover spell... Lola never mentioned that form." She's in a deeply serious situation right now and couldn't use her spirits to call them. Her magic is getting low and Celestial is going to use it wisely before she could pass out.

David coldly laughs as it brings Robin and Kid Flash shiver down through their spine. "I experimented with them! The more I killed and obtained their power, I will be unstoppable! Haha!"

"You're sick!" It brings tears from Celestial's eye. "They're your family!"

"A weak family!" David snapped back angrily. "They don't deserve to have this lost magic. It should be me!"

"Killing them is the right way to become powerful!?" Her hands glowed with a magic circle. "Kurisutarumeiku: Shādo no arashi (Crystal make: Storm of shards) what makes it so special about this lost magic? It only brings nothing but greedy and power."

David suddenly disappeared and appeared behind her. "Everything!" Raising his arms to stab Celestial.

"Celestial!" Kid Flash and Robin cried out her names.

"Ha!" A yellow blur deflects the attack and Celestial gasps in shock. "I would never let anyone harm my friends!" Pushing David away and breathes heavily.

"Angel!" Celestial gasps to see their halfling is joining them.

"You guys are taking too long and decided to help you out." Angel gritted her teeth angrily and pushes David away from them. "The League noticed Kitsune and Lust are wrecking the theatre hall." She explained and noticing Celestial is covered with bruises especially her right swollen cheek.

"Tch." David is clicking his tongue and senses someone is aiding the young heroes soon. "Till next time, you scum." He shattered himself into pieces and Angel clicks her tongue in annoyance.

"That pretty boy happened to be a bad guy." Angel commented bitterly and Celestial sighs tiredly.

The crystals surround Kid Flash and Robin disappeared as they approached the girls. Celestial legs are shaking and couldn't stand anymore as Robin immediately catches her. "Ro...bin." She muttered his name weakly.

"Hey... you're going to be okay." Robin assured his girlfriend. He could tell she's tired of casting a lot of spells either defensive or offensive attacks. "We already have someone to help us. You can rest now, my love."

Celestial nodded her head weakly before closing her eyes. She never used a lot of crystal magic and dueling one of Mendoza's traitor clan. The scarlet-haired girl vowed if she sees him again, she would give the other Mendoza's clan for justice and never cares for her life.

Mount Justice || December 21, 00:00 EST ||

Aaliyah remained silent as she stares at the ground in deep thoughts. She changed her clothes to a casual plain white-shirt and black jeans. The blonde girl gritted her teeth angrily for failing to defeat Lust as she escaped from her grasps before they could grab her. It makes her wonder how she managed to get in here and found her. The first Master of Fairy Tail pop out of Aaliyah's mind, she remembered there's a dangerous enemy lurking behind the darkness. Could it be Lust and David are one of the dangerous enemies behind Mavis's warning?

"Damn it." She swears and slamming the bed with her unusual anger look. "Of all people, why does it have to be her?"

Knock!

Knock!

"Aaliyah? May I come in?" Hearing Kaldur's voice and she sighs silently.

"Come in." Aaliyah answered and regaining her composure. "How are the others?" She asked the Atlantean curiously.

"Everyone are fine." Kaldur answered truthfully. "Kurama healed Ruby's injuries including her magic and Robin stayed by her side."

"I'm glad she's okay." Aaliyah sighs in relief. Zara informed her David is one of the Mendoza Clan and the culprit who brutally murdered all his members to become a powerful crystal mage user. Ruby's life didn't reduce as she used a lot of crystal spells because they're dueling if she's worthy enough to wield the crystal or not.

"How are you feeling?" He asked her worriedly.

"Still wondering how she managed to find me." She answered with a thoughtful look on her face. "I didn't know David is a wizard like Ru-chan, Zara and I."

"Arthur is right about David." Aaliyah stares at Kaldur with a skeptical look on her face. "He sensed something off about him and the way he treated Ruby badly. How did you know about Lust?"

"She's one of the dark guild members or Grimoire Heart and their secret trump card." Aaliyah answered and stared at the floor. "She's well-known for being a sadist and we have similar magic."

"How?"

"Lust despised me because we share the same element, water. Lust have Water God Slayer magic." Aaliyah explained and noticed Kaldur's confusion. "God Slayer magic is a form of ancient and lost magic. Dragon Slayer like me was been taught by dragons depending on their main elements to train magic. God Slayer magic utilizes their own magic depending on which elements they want. However, no matter which elements you eat, their element has black color."

"She despised you because you shared the same element?" Kaldur asked her curiously.

"No, apparently their Master is a bit obsessed with me because grandpa wanted me to be the next Master to lead the guild." Aaliyah answered with a serious look on her face. "He sees my potential and Lust hates me because I have her Master's attention more than her."

"I see..." Kaldur isn't surprised because everyone knows Aaliyah is a powerful mage despite she's holding back her powers for their sake. There are times Aaliyah would rarely lose temper and showed her real strength. It frustrates him sometimes because he couldn't read her well by masking emotions. "How did she able to call the shadows?"

"She has a small artifact to call the shadows and aid her." Aaliyah answered and glared at him. "Next time when I said leave, you leave, Kaldur-san ."

"You know I can't leave you behind knowing Lust nearly killed you, Aaliyah." Kaldur pointed out and narrowed his grey eyes at her cerulean eyes.

"I fought her before you did, Kaldur-san." Aaliyah retorted back angrily. "You nearly got killed by the shadows if it wasn't for Arthur's magic. If you ge-"

"I would never abandon my comrades behind whether they like it or not." Kaldur cuts her off calmly. "Aaliyah, I saw you're exhausted from the fight between you and Lust."

"You think with your help- you can stand against her?" Aaliyah stands up and ignoring her pain. "Kaldur-san, she's out of your league!"

"You think you're strong enough to defeat her, Aaliyah!?" Kaldur raises his voice and Aaliyah didn't flinch. "Aaliyah, I'm tired of you pushing us away for the last couple of days. Please, tell me, what's wrong?" He pleadingly asked to express her thoughts.

Aaliyah remained silent but looking down on the floor. She usually expressed Arthur to poured out her thoughts as they're similar to their past before. Her blonde fringe covers her cerulean eyes and jumps in surprised to feel web-hands on her cheeks.

"Aaliyah, look at me please?" He pleads and holds her face to see him eye-to-eye contact. "It hurts me to see you closing off your emotions. Distancing yourself other people-"

"Stop it, Kaldur-san." Aaliyah cuts him off and distancing herself from the Atlantean. "Just don't." She didn't want to get hurt again like the way Hibiki broke her heart.

Kaldur finally realizes she knows his affections towards her. "I-"

"I don't want to be with someone who doesn't get over their feelings to someone else." Aaliyah starts to walk away. "I don't want to be your rebound, Kaldur-san." She left infirmary leaving Kaldur in his shocked state.

Kaldur didn't expect Aaliyah knew he fell in love with someone else before. Tula rejects his feelings because she could see it in her eyes her friend loves someone else. The Atlantean girl pushes Kaldur to confess his feelings towards the blonde girl. Arthur warned him Aaliyah would reject him whether she has feelings for him or not due to her terrible pasts. The brunette didn't explain further why she's distancing herself for the past couple of days. He wouldn't give up and finally found someone worth fighting for.
