The People began to cheer for the competitors as Yugo was hugging his older brother. "Nii-san! You made it!" Akira said, "Good to see you too little bro. Wow! You have grown up so fast."

Yugo asked, "How is our father? Is he taking the meds?" Akira was upset and spoke, "Yugo! How could stoop into falling into a foolish trap!" Yugo was deeply startled and begins to say, "Elder brother? Why are you so upset?"

Akira replied, "Back when our father was killed by that same man, He was only after you because you are the secret to unlocking the power of the Sacred Fist!" Akira noticed the people cheering and noticing a space station floating in space. "The Death Star must not be unleashed!"

Yugo said in concern, "I've never seen my brother so angry." Rebecca, the older sister of Kazane and Hyoma said, "It is because of this." Rebecca showed Yugo the blueprints of the planet destroying space station, the "Death Score".

Sessue then added, "It was fated that when the Aliens visited the Roman Empire, they gifted Emperor Augustus the construction materials and the blueprints needed to build a planet destroy space station. The drones managed to use the materials to turn the earth's moon into the Death Score or as others called it the Death Star."

Hyoma said, "And that's how my sister Kazane got the pendant."

Saul Angelo steps in and said in seriousness, "Ooooh... this explains why the US Government wanted to keep that space station project a secret."

Akira was approached by Steve Lattner. Steve said, "Yo! That mean thing ya did to your bro is was passed cool!" Akira told Steve, "If my brother returned home earlier, none of this should've happened!"

Sai Long, Su Qingtao's friend came and said, "I understand your frustration and the loss of your father. But it wasn't really his fault. Your brother has been training to be even stronger than he was." 

Akira replied, "I know.... my brother's growing stronger. I didn't want him to be a bit clumsy."

At the first match of the tournament, Yugo defeated Allen Marzipan, while Su Qingtao was defeated by David Human who was determined to win and clear Mark Galeon's name. Jelly Thomas was defeated by Sessue Kanoh while Steve Laettner was defeated by Cindy Yoko. At the same time, Akira Sangunji defeated Billy Thomas with a bit honor and bravery. Douglas then defeated Darius Sobieska while Hong Yuli defeated Dong Chimney with her drunken fist techniques and finally, Sai Long defeated Ryu Sakazuki due to his loss to him in the his previous match in the past.

In additon, James Carter was defeated by Selena Topaz, a nature-loving capoeira fighter and a princess of an ancient tribe of Africa while Hildia defeated Hong Leiteng and Arthur Stewart mercifully defeated Ann due to his connection with her. Rebecca defeated Mato Sangunji due to Akira's connection to her sister.

Yugo was a bit warmed up and ready for anything and said, "That's my brother. Always staying strong and standing tall."

As the first match continued, Hyoma notice something in the air. Rebecca defeated Jin Kaphwan with her own techniques and remained confident. She said to her younger brother, "Keep it up Hyoma. We will get our sister back."

One night, Yugo approached his older and said, "What's wrong brother?" Akira, filled with concern and guilt, said to Yugo, "Yugo. The reason I have to come to the ruins of the Roman Empire was to save Kazane. I struck a deal with Douglas in order to stop the completion of the nineth Death Star."

Yugo added, "Brother... I don't need you go through these vengeful thoughts to suppress." But Akira said, "Have you forgotten... The legend of Darth Vader. The aliens from the alternate dimension left that legend and the depiction of Darth Vader in a giant red cube."

Yugo hugged his brother, knowing that his father died to protect the secrets of his family. "I know. I missed him too. Time slowly flows by since the day we left the nest."

Akira said to Yugo, "I will do what ever it takes to protect you. No matter the cost."

At the hidden chambers of the Colosseum, Hyoma was spying on Kaiya Tsubaki who was talking to the aliens about the immense completion of the Death Score. After safely evading them, Hyoma found Kazane, sleeping in steel collar and chains. "Kazane..." He whispered. Kazane a kunoichi dressed in white long sleeved kimono with red hakama and ribbons, dark blue cuffs, white tabi and rice straw sandals.

Kazane opened her eyes and said, "H.... Hyoma.... Hyoma?"

Kazane smiled and sees her younger brother fully grown and healthy but sees Kaiya grabbing Hyoma.

Kaiya said, "I know you want your sister back, but you need some rest." He then dragged Hyoma to Yugo and Akira's room and tossed him.

Akira catched him and said, "Are you alright?" Hyoma said, "I'm fine. I found my sister but Kaiya caught me and doesn't like others taking sneak peeks." 

Hyoma explained to Akira and Yugo everything about the Death Score and the aliens that struck a deal with Kaiya in finishing up the progress of its construction.

Akira said in concern, "I know we want to rescue her but the second match comes at sun rise."

In the second match, Akira defeated Hershey Streit with sheer wit and determination. Continuing to compete in the tournament, Yugo defeated Takeru Mishimo by using a simple karate chop on the neck. At the same Cindy defeated Hong Yuli while Saya defeated Sai Long with determination as she saw her father watching her.

While Yugo carefully befriended Selena Topaz after defeating her in battle with romance and iron fists, Sessue successfully defeated Mark Galeon. Hilida was defeated by Arthur as Sessue ends up being defeated by Rebecca.

When walking across the Colosseum and seeing the view of the ancient ruins of Rome, Douglas Anderson was ambushed and caught off guard by Cindy. "My sweet Douglas! You have been very naughty to yourself as time goes on." Douglas spoke and said, "For a fiesty lady, you are really good in Koppo."

Cindy pinned Douglas onto the floor and told him, "Women such as myself are good in martial arts. Don't underestimate the woman who knows Koppo." Douglas didn't dare what was her next move. There was the arm breaker techniques. "This is gonna be an ouch!" Cried Douglas and he shuts his eyes.

His arm twisted. broken arm bone twinkled, the pain was inside his muscles is terrifying. Douglas felt a certain injury on his shoulder. He clearly gets up with hesitation.

Cindy turned to Douglas. "Sweet little Koppo Boy." She teased. "I am after you in the third match. Hope you could keep up with that broken arm of yours." She walked away.

In the morning, at the beginning of the third match, it's Koppo vs. Koppo. Cindy vs. Douglas. Douglas struggled to keep up with Cindy's movements. As Douglas attempted to pin his opponent doen by the leg, Cindy boasted about Douglas's weakened, "Hah! I knew you'd tried to do the same thing!" She uno reversed Douglas's technique and smacked Douglas to the floor by the head, knocking the detective and a strong fighter unconscious.

Akira, Yugo, Hyoma and Rebecca watched as the Tsubaki Corporation's medical unit takes Douglas to the medical chamber section of the Colosseum.

While Saya was unable to defeat Rebecca with her grudge getting a better of her, Hyoma managed to defeat Arthur by using his motion sensor technique. His skill allowed him to anticipate the movements of a person when used in combat while Akira managed to defeat Hong Yuli with a hint of merciful means while Yugo was successful in defeating

Before the semi-finals, Akira and Yugo made a promise to each other. Akira said, "If one of us have to save Kazane by defeat Kaiya, I'm certain that the Death Star's launching sequence will stop!" Yugo replied, "Older Brother. I don't want to hurt you but remember what our mother use to say?"

Akira knows his mother's words and said, "I know little bro. Vengeance is not the way of being the Karateka. The rage is not ours to keep and wield."

Yugo then added, "I hope that you don't lose to Kaiya."

Unknown to Yugo and Akira, Cindy Yoko was watching from the sidelines and Kaiya said, "Don't you worry Cindy. You will witness the full glory of the fully armed and operational battlestation."

Underneath the Colosseum was a massive hanger bay created by the aliens and inside it was a massive mobile, planet-destroying superweapon, the Death Score.
