Z-Arc was a formidable enemy, there were no doubts it would have been a difficult duel, so each girl quickly brought out their most powerful creature, to even stand a chance against the mighty monster.
"Fusion Summon! Help us, Melodious Bloom Diva!" Zuzu called hers first.
"XYZ Summon! I'm counting on you, Lyrilusc: Assembled Nightingale!" Lulu followed suit.
"Synchro Summon! My most trusted partner, Windwitch - Winter Bell!" Rin was next.
"Fusion Summon! Come forth, beast of the night, Lunalight Leo Dancer!" Celina was the last one.
All monsters descended on the battlefield side by side in front of the massive Supreme King Z-Arc, the duelist, now fused with his dragons, became the ultimate duel beast.
Z-Arc was not worried in the slightest about their new monsters, in fact he started to laugh maniacally.
"Didn't you paid attention when I destroyed your dear friends? I can't be destroyed by card effects, can't be targeted either and all your monsters have their effect negated, there's nothing you can do." The evil being explained all the tools his monster or better himself had at his disposal.
He was quick in destroying all off them, all were with few LP and only Celina had still her monster left.
"My move, I attack Lunalight Leo Dancer with myself, goodbye fusion girl" Z-Arc ordered his Dragon to finish off Celina.
"I activate my Quick Play Spell, Book of Moon! It can flip a monster on the field face down, and since I can't flip you, I'll use it on my monster to not take battle damage"
Celina announced promptly.
The attack went through on a defense position Leo Dancer which got destroyed and Celina was safe at least for now, but the situation was desperate.
"Damn, we really have nearly no moves left... the chance of drawing Rei's cards are so low, it really might be over..." Celina thought slowly losing her confidence.
"But I can't give up, Yuya would never do it, I know we can believe in Rei's words." Celina stopped her train of thoughts.
"You really want to suffer then? I'll finish you off next turn. Your move, assuming you can do something eheheh" Z-Arc smirked in amusement.
"The duel is not over until the last card is played, you don't scare me!" Celina tried to found the strenght inside her.
"Your friends there are probably not on the same page, look!" Z-Arc said as Celina turned to look at her 3 partners and he was right.
"We can't do anything..." Rin was on the point of giving up.
"He's unbeatable..." Lulu was in the same predicament.
"I'm scared..." Zuzu similarly was paralysed in fright.
Celina felt the fear hit her, even if she didn't want to admit, she felt the same way, just like that night in the Synchro Dimension, powerless because of that stupid gas, she slowly dropped on her knees.
"AHAHAHAHAH, I'll reign supreme over every dimension" Z-Arc shouted with all his might creating a shockwave.
"It' over..." Celina was on the verge of giving up, but then a voice called for them from the sky.
"Just believe in yourselves, you are our last hope! I thought you wanted to save the boys victims of Z-Arc's scheme! Do you think they would give up if you were in their place?" Rei said trying to give them hope again.
"Yugo would never give up" Rin said trying to stand on her feet.
"Yuto either." Lulu tried to do the same.
"Yuya would do anything for his friends..." Zuzu said in the same spot.
"I know, Yuya saved me, now it's my turn to do the same!" Celina stood up with newfound determination.
Just then the card on top of all 4 girls' Duel Disks started glowing brightly.
"What?" Z-Arc also didn't understand.
"IT'S OUR TURN!" All girls shouted at the same time.
Their eyes couldn't believe it, but they all drew Rei's secret cards.
"Got get your friends back!" Rei cheered before disappearing.
"I start by activating the continous spell, En Winds before ending my turn! Rin announced.
"This can't be, not that card... but alone still isn't enough..." Z-Arc lost his cool for the first time in the duel.
"Here's an other continues spell, En Birds!" Lulu continued before also ending her turn.
"No..." Z-Arc already knew what was coming.
"And the third one, En Flowers! Zuzu also made her move.
"Impossible, I can't believe it!" The monster was having a taste of his own medicine, fright.
"You better believe it, because last we have En Moon!" Celina spoke as the mithical combination was complete.
"NO, NO, NO, not this again!" The monster was shaking now.
"Try to reach for your friends now! It's the moment to get them separated and seal Z-Arc away forever" Rei instructed.
"Yugo..." Rin spoke.
"RinRin..." Yugo's voice could be heard faintly
"Yuto..." Lulu spoke.
"Lulu..." Yuto was also able to hear.
"Yuya!" Both Celina and Zuzu said simultaneously.
Yuya was then able to take back control over his body, his eyes turned back to their usual assuring red.
"Celina! Zuzu! It won't probably last long but I can help you put an end to this! Thank you, you saved me from the darkness" Yuya said trying to restrain Z-Arc as he had tears in his eyes, but they were from happiness.
"I'm so glad you are ok, Yuya!" Zuzu had tears in her eyes.
"Yuya, please come back, you still have to put a smile on others' faces, all your friends need you, I need you! " Celina called in her sort of confession.
"Do it, we'll be fine! End this duel! Yuya, Yuto and Yugo yelled.
"And even Yuri at this point, I guess..." Celina tought.
"ACTIVATE" The 4 girls shouted.
They activated the final combination of the 4 element of nature as a bright light enveloped everything in sight.
Z-Arc was defeated, but what will happen to the boys? And to the girls?
