During the duel between our heroes and the professor, Yuya was uncertain of what to think about the ordeal of being Z-ARC.

"I'm not Z-Arc, this isn't true..." Yuya said facing Leo.

"Yeah, tell him Yuya" Decklan agreed.

"Really? Let's check then... How would you feel if I did hurt the girls? You become really attached to both Zuzu and Celina if I saw correctly" Leo said trying to expose Yuya's darkness.

"YOU WOULDN'T DARE" Said Yuya in a demonic like voice, with his eyes burning with rage.

"You see son, that's Z-Arc right there, I didn't lie about a single thing, we should join forces and destroy him before it's too late" Leo resumed trying to bring Declan to his side.

"He's wrong, you're not Z-Arc right Yuya?" Declan asked but the doubt was present in his voice.

"Yuya, please calm down! He's only trying to enrage you!" Celina shouted worried.

"She's right Yuya, we must keep our rage in check or Z-Arc will really take over" Yuto said in a similar enraged state.

"I'm trying, but his influence is too strong..." Yuya said to Yuto.

But it was too late, his wrath has reached whole new levels, the powerful monster was slowly taking control.

"Now where were we? Oh, yeah, I attack directly with my Odd Eyes Raging Dragon, to end your pathetic life!" Yuya said with visible insanity in his gaze.

"It's over then..." Said Leo accepting his defeat.

Just then a man intervened activating a card that restrained Yuya, keeping him tied a column, and saving Leo's life, it was Yusho Sakaki, Yuya's lost father.

"Who are you, and what did you do to him?" Celina asked the man for answers.

"I wouldn't be a good father if I didn't stop my son from doing something bad, pleasure to make your acquintance, all of you, I' m Yusho Sakaki, Yuya's father" He declared with trepidation

"Yuya's father? He always said you disappeared mysteriously when he was a kid, what happened exactly? " Celina was still rightfully doubtful.

"This is not the moment for that, it's a long story, now we need to help Yuya" Yusho said with a longing look.

Celina turned over the boy she secretely liked, even if not understending it herself.

"He lost control, and I can't do anything to help him... forgive me Yuya" Celina said in shame.

"Actually, maybe you can help him, try to reach for the real Yuya, I can read in your eyes that you deeply care for him, your voice combined to the power of the bracialet may be able to break through the darkness" Yusho explained his theory.

"I'll try sir, I own that to him, he saved me from my loneliness" Celina was now determined.

"Good girl, we are counting on ya" Yusho smiled

Celina took a big breath before starting.

"Yuya, you were always there for me when I needed it, because being beside you, even in the worst moments gave me strenght. You taught me how to smile even when I felt like crying, the feeling of being cared was something absolutely new for me, I was always on my own and it really felt good... I really want to feel that again so please, come back to us, to me..." She chanted about her internal feelings, something she has never done before, as her bracialet started glowing.

"Celina..." Yuya seemed to be hearing her even if just a little.

"I'm here Yuya, we are all here for you..." She got interrupted as someone got launched into the room screaming.

It was Shay, wounded and defeated.

Lulu soon came beside her big brother.

"Shay, what happened?" Lulu asked in tears.

"That guy, Yuri is coming, he defeated Yugo, and he absorbed his power in some way... I got defeated too..." Shay said before fainting.

"So here it is the party uh? Why wasn't I invited?"

Said Yuri with a grin as he entered the room.

Just then Yuya freed himself of his binding, reading himself for a duel.

"Celina, Zuzu, and everyone else, I'll take care of him" Said Yuya, the demonic voice dissipated slowly.

"Sure you can handle it?" Celina was still worried about Z-Arc's influence but hoped her words made effect.

"Trust me" He smiled as only him could do.

"Fine, but come back safely and victorius" Celina conceeded.

"Let's start Yuya, I was looking forward for this, I'll absord your power too soon enough!" Yuri smirked reading his own duel disk.

"Please, protect Yuya from the darkness" Celina thought in a praying pose as the duel began.
