As they enter the apartment, they heard a strange song that was played with a violin or a viola, and it was oddly familiar.

"Weird, I never heard anyone except Gumina play the violin before." Sateriasis calmly said, and the Sinners walk inside to see Mammon was the one playing the violin song.

Then suddenly, Held and Sickle pushed Gallerian and Sateriasis and the two lovebirds held their hands.

"Now, shall we dance?" Sateriasis asked with a smile. Gallerian blushes and he nods.

They begin to dance, and someone jumped up and scared the Sinners.

"AH!" They all scream in unison and they fell down and laughed.

"Sorry, I was in the mood to do that." Seth -for it was obvious by the brown hair and glasses- apologized as he scratched the back of his neck with a awkward grin. All of them sat down at the floor, smiling.

"Though simple, I love it!" Margarita said. Mammon smiled.

"I want to see Gallerian and Sateriasis dance again." Mammon suggested.

At the mention, the only male Sinners blushed madly and they crossed their arms and looked away.

In this moment, Beezlebub laughed, and he was in a waiter outfit with many food and drinks he held in just a single tray.

Banica's eyes sparkle with delight, and she licked her lips.

"Oh, isn't it time for a snack?" Riliane and Alexiel asked in their prideful matter. Lucifer appeared in his raven form with a grin.

"Let's EAAAT!" Banica yelled, and Beezlebub ran faster than Banica, and the others catched up.

Eventually, they reach the dining room, and all sits down.

"Snacks are served!" Beezlebub exclaimed and he served a carcass of the First Alice, and her head to Banica.

He served Riliane and Alexiel brioche and tea, served Gallerian mint chocolate chip ice cream, served Nemesis and Kayo tuna sashimi, served Sateriasis some regular Asmodean food, and served Margarita typical Elphe food.

Banica tries a bite of her served food, and she had a happy smile.

"DELICIOUS!" She yelled, and Riliane smacked her gently out of annoyance.

"Have manners, lady!" She yelled.

In a corner near the dining area, Seth removes his glasses, and suddenly, his left eye hurts.

"Ah!" He yelped in pain as his vision on his left eye blurs and he collapsed in pain, just as how Sateriasis collapsed when he was assassinated by Karchess Crim via Grim the End and he covers his left eye.

Margarita noticed him and she leaped to his position.

"Are you alright, Seth?" She asked. He shook his head.

"No..my blind eye hurts.." The Demon replied, and he twitches in pain.

"May I see?" Margarita sweetly said, and she removed Seth's hand covering his eye, and she was shocked and widens her eyes.

His left eye was about almost cracking, as if it was glass. His pupils are in the color white, not black.

"The reason why it's cracked like that because if I did not have my eye contacts, that will show up." He started, and he looks away from Margarita.

"Also, this eye is blind - it's a blind eye." Seth explained in a simple sentence and he closed his blind eye.

"That's why I prefer my glasses or my Mask with a Will, not just stupid fucking contacts." Seth cussed.

Margarita kissed his closed eye and Seth blushed and he looked at her.

"Margarita.." Seth uttered, and with no hesitation, he kissed her.

The Demons and the Sinners present in this scene squealed, especially Lucifer.

Margarita, despite the shock, kissed back and released the kiss, and Seth's eye is not cracked like before, and his pupil was black, not white.

"Wait..I healed his blind eye?" Margarita thought to herself as she widens her eyes.

"Seth! Your eye!" A Demon -either Mammon or Lucifer or Beezlebub said it, no one knew who it was- exclaimed.

Seth heard the exclamation and he tried to cover his right eye to see if his left eye is working.

And it worked, it was not blurry.

He remove his hand and he ran to somewhere downstairs, and the others followed him.

They have reached a dark room, and everyone held each other so that they could not bump into something.

Due to him being able to see anything in the dark, Seth easily found the switch for the light to open.

"Behold, the hidden masquerade ball in this apartment!" Seth proudly presents, and he turned on the switch, and a grand dancing hall and a two thrones at the very end of a room.

Nemesis' good eye spotted a door behind one of the thrones, and she whispered it to her Demon.

The Demon replied and the two smirked.

"Before you enter, you must and of course, wear some 7th EC costumes. And, for Gallerian Marlon,

You have to crossdress like what Karchess did to your lover before killing him." Seth said with a devilish smirk.

The latter blushed madly.

"That's fucked up, Seth! I don't want to!" Gallerian complained, and Nemesis poked his cheek.

"Dad, Karchess may have passed down a trait that he had. Maybe his voice, when you can mimic a woman's voice." Nemesis said. Gallerian blinked his eyes thrice. He nods to the two Sinners he's known for quite a while: Riliane Lucifen d'Austriche and Sateriasis Venomania.

Sateriasis drags Gallerian to a really spacious closet.

"Hey, here's the hair extension." Riliane called out and gave it to Sateriasis.

Sateriasis then locks the closet door.

"The ball will not start yet, all the others are now going to be dressed then, alright?" Sateriasis reminded Gallerian and he nods.

"Here is the clothes I found here." Sateriasis said and he gave his lover the blue dress resembling Riliane's clothes.

"Alright." Gallerian said, and he strips off his shirt and vest, exposing his white torso.

"Wow, I never knew you had muscles, my dear." Sateriasis chuckled. Gallerian blushed.

"Shut up. And plus, I'm not that sexy." Gallerian said, but Sateriasis kabedons him at the wall.

"Yes, you are." Sateriasis said, and he sets Gallerian free.

"Wear it now, the guests are waiting for us." Sateriasis said and smiled.

Gallerian strips and he wears the beautiful dress.

"I can't tie the corset." Gallerian said. Sateriasis went to his back and he ties the corset a little tighter.

"Can you hold it in, darling?" Sateriasis asked.

He suffocates a little.

Sateriasis loosens it a little and Gallerian breaths just fine.

"There." Gallerian muttered. Gallerian turns to him and smiles.

"Now the extension.." Sateriasis uttered and he puts the hair extension on Gallerian, and he widens his purple eyes.

"Your..beautiful.." Sateriasis muttered.

They went outside after Gallerian puts on make up to make it legitimate, and it stunned the Sinners when they saw Gallerian.

"Wow." Nemesis said.

Nemesis wore a green dress reaching her lower knees. Her hairpiece is similar to Kayo's yellow hairpiece, but not the same thing in one way. Her shoes were high-heeled black boots, and under her dress was the case with a revovler and her Key of Wrath..[Punishment]'s key to be exact.

Kayo wore a dress resembling Elluka Chirclatia's dress, except the color was the same as her kimono and still wore her hairpiece. Her shoes were high heels that resemble a geta, which were Japanese sandals. She held her scissors just in case.

Riliane wore a dress that was more extravagant than her favorite dress, and her hairpiece was a crown, signifying that she was a princess, no, a queen.

"Do I look good, ladies?" Gallerian asked, and all the girls nod.

"You are the perfect crossdresser ever, no lie." Banica commented, wearing her dress that Carlos gave her.

Gallerian curtsies.

"Thank you very much." He thanked with a woman's voice, his alternate voice, actually.

"Aside from that, what name should I have? As a lady, of course." Gallerian asked.

Seth walked in with a suit that looks like Kaspar's clothes, just with differences.

Margarita blushed.

"Ah..Seth.." Margarita started. Seth looked at Margarita and blushed, then looked at Gallerian.

"Perfect choice, Marlon. Anyways, the name can be Elizabeth." Seth suggested.

"Then his surname is still the same, yes?" Sateriasis asked and Seth nods.

"Here are the masks." Seth said and gave all the Sinners a mask, and he wore his Mask with a Will, but this time, it has two holes, since his left eye is not blind anymore.

"Wear it now, we are going in." Seth whispered and he comes in.

All the guests saw him, and all the Sinners bows along with him. Riliane walks inside with Alexiel, and Alexiel was dressed in his clothes as a prince.

"Ohohoho! Now, bow to me!" Riliane ordered, and everyone did so.

While everyone bowed to her, Riliane and Alexiel walks towards the thrones and she sits down and crossed her legs.

Sateriasis and Elizabeth entered the room.

"Who is that girl with the Duke?" The guests whisper to each other, and the lovebirds bow.

"May I introduce my fiancée: Duchess Elizabeth Marlon." Sateriasis introduced Elizabeth to the crowd and she curtsies while blushing.

Riliane and Alexiel smirked.

"Nice to meet you, Duke Sateriasis and Duchess Elizabeth." The Lucifen twins greet in unison.

Riliane stands up.

"Now, we shall start the ball!" Riliane announced.

Everyone dances.

"Hey, Lucifer, our plan." Asmodeus said and he winks at the cross-dressing Lucifer and smirks with Asmodeus.

"Now, shall we dance?" Sateriasis asked his fiancée. Elizabeth nods and Elizabeth winks at her Demon and Mammon plays the violin.

"Is the song..Cantarella?" Elizabeth whispers to Sateriasis, and the Duke nods.

"Probably." Sateriasis whispered back. Sateriasis then twirls Elizabeth.

"You know, I enjoy dancing with you, Sateriasis." Elizabeth admitted, smiling.

Margarita and Seth danced together and they smiled.

Nemesis, while lingering around the dark areas, eats carrot-flavored lollipop. She throws it away and she saw a woman with blond hair about to stab Sateriasis.

The woman was no other than "Karchess Crim", the killer of Sateriasis.

"Venomania! Look out!" Nemesis yelled and she got out her hidden revolver and runs. She inserts the Key of Wrath that turned into a bullet in the muzzle of her revolver.

The guests gasp.

The masked Seth smirked, along with his fellow Demons of Sin.

"Now, Nemesis!" Seth yelled. Nemesis smirked.

Sateriasis looks at his back and saw "Karchess Crim" about to stab him and widens his eyes.

"Karchess" was a inch away from stabbing Sateriasis, but Elizabeth glides and she swiftly disarms "Karchess" and the blade went in the air and Nemesis caught it just in time.

"No more killing, Karchess Crim." Nemesis and Elizabeth said in unison and smirked.

Elizabeth winks at" Karchess".

"You know who this is, yeah?" Elizabeth hints to "Karchess", and "Karchess" widens his eyes.

In a split second, Elizabeth pushed her lover away and Nemesis shot "Karchess" in the heart.

"AH!" "Karchess" yelped. Sateriasis glared at him.

"Long time no see, Karchess." Sateriasis greeted. "Karchess" sneered at him.

"You..bitch..!" "Karchess" cussed. Asmodeus laughed.

"Well, Karchess, that bullet completely penetrates you in a few seconds, and guess what golden bullet I used~" Nemesis explained and by the end, she made a sing-a-long tone.

Seth snapped his fingers and the Key of Wrath stabbed Karchess, and blood pours out.

Kayo blocked Banica out of the way.

"Banica-chan, don't. We don't want anyone know that your a cannibal, hai?" Kayo warned her distant relative and the gluttonous cannibal nods and stopped herself.

"Thanks." Kayo thanked and smiled.

Riliane and Alexiel widens their eyes and they rose from their throne and they covered their mouth and hid their smirk.

"Your highness! What are you going to do?!" Leviathan called out and smirked.

Her pink eyes lit up.

Riliane saw what happened and she realized what she must do.

Riliane removed her mouth and she made a hand gesture, and light came out. It was purple.

"Now, come forth, twin of the fallen angel Lucifer: Lucy!" She ordered, raising her hand.

At this moment, Lucy was summoned.

Lucifer widens his eyes in revelation.

"My twin..." He thought to himself.

Lucy also had purple eyes, like her twin. Her blond hair was tied in a long ponytail.

Her clothing was similar to Alexiel's, with the white collar, yellow-orange like coat with pointy end, cream-colored vest but with minor changes.
Lucy's pants has a skirt up to her knees and her boots were brown. She had red bracelets.

Like Lucifer, she has black wings, but the chains were red and there was no Four Mirrors of Lucifiena. 

"Bonjour, Alexiel, Riliane, and.." Lucy stopped when she noticed her twin brother.

"Lucifer." She said, a quiet smile crossed her face.

She stepped down and glanced to "Karchess" and she went to his body.

"Congratulations, Master of the Hellish Yard." Lucy congratulated with a smirk.

"It is a honor, Lucy." Nemesis thanked formally.

Lucifer ran to Lucy and hugged her.

"Why would I even forget my own twin sister's name...?" Lucifer softly mumbled, crying.

Lucy widens her eyes in shock.

"Lucifer..I.."

Riliane and Alexiel was shocked about this.

Riliane went to Mammon.

"Why did Lucifer forgot about Lucy?" She asked.

The Demon sighed.

"While your brother was in a clockwork, Lucy was thrown in there, too, but in a different way. All in those years, Lucy was trapped in there, never knowing how to escape."

"Due to the long time, Lucifer eventually forgotten about her."

In the shadows, a smile creeped out.

"We shall see the play in Evil's Forest."
