Note: Who is Zhong Ji Yi Ban?

To bring you readers who don't know the K.O. Series and would like to know a bit of information to catch up in order to read this story with more sense, (and because I'm really, really sleepy and it's 3AM, dudes...) I'll quote from summaries made from Wiki now, and put a bit of information from my input later during the story so it makes more sense as you're reading.

The story you're about to read will basically be set between the last two seasons listed in this page.

Season 1: Zhong Ji Yi Ban means "The Ultimate Class".

The Ultimate Class is a class designed specifically for students who have been rejected by other high schools for trouble-making. The strongest student, Wang Da Dong acts as their leader and everyone in that class is bound to answer to him. When a gangster leader's son, Wang Ya Se; and the legendary king of fighters, Ding Xiao Yu join the class, they become best pals out of some fruitous events. The three of them are top five KO Ranked fighters with extraordinary powers, which attracts more trouble as more people come to challenge them. Among one of them is Da Dong's childhood best friend, Lei Ke Si, who has been pretending to be a weak and kind-hearted boy to hide the fact that he is also one of the top 5 KO Ranked fighters. Ya Se is the first to figure out his true identity and intentions, but because Da Dong thinks of Lei Ke Si as his best friend, he refuses to believe him. And after various mischiefs lead to Ya Se being the culprit, his friendship with Da Dong turns hostile.

Aside from the every day challenges, the trio also face problems in their personal lives, as Xiao Yu falls in love with Da Dong's girlfriend, Huang An Qi, and their loyalty is put on trial.

After going through these events, the last thing they need is to face off their ultimate enemy, who has been building his power by collecting minions and destroying powerful martial artists. In the end, Da Dong, Ya Se, Xiao Yu, and their returned friend, Lei Ke Si, all work together to defeat their enemy, Hei Long, but lose their powers in the process.

Season 2: There are many different universal dimensions in the world. This season specifically zeroes in on the Iron Dimension. Last season took place in the Gold Dimension.

This series picks up what happens after the KO fighters' last battle against the forces of darkness.

Da Dong's friend, Xiu, hopes to help Da Dong, Ya Se and Xiao Yu restore their powers in order to turn the war against the darkness to good's favor, much to Da Dong's pleasure. After going through many failed experiments, Xiu tells them of the existence of the twelve dimensions and their alternate counterparts, who may be their last hope in restoring their powers.

Since the other ten dimensions have already been conquered by darkness, Xiu can only travel to his dimension: the Iron Dimension. There, he meets Da Dong's alternate counterpart, Xia Tian, who has very special powers but has little control over them. Upon realizing his potential, Xiu suspects that he may have the potential to become the legendary Ultimate Iron Man; a power-user prophesised to hold the ultimate power and known as the savior of worlds. Xia Tian, however, is not interested in using his powers at any purpose and mainly focuses on improving his musical skills in hopes to one day become a rockstar musician. However, after going through some dangerous events that almost get his family and loved ones killed, Xia Tian realizes that he needs to be stronger to be able to protect them, and so slowly focuses on becoming the Ultimate Iron Man. However, what he doesn't know is that he needs to go through many trials that will put his body and heart in pain before he can become the one.

As time goes by, Xia Tian becomes more powerful while Xiu finds Ya Se and Xiao Yu's alternate counterparts;Lan Ling Wang and Jiu Wu, who also possess extraordinarily powerful gifts. However, Lan Ling Wang is a servant of a powerful dark family, who later takes away his powers and annihilates his family. Meanwhile, Jiu Wu cannot restore his alternate counterpart's powers because he needs to constantly transfer his power to theforce field that protects the Iron Dimension.

With all of their alternate counterparts preoccupied and powerless, respectively, how can Da Dong, Ya Se and Xiao Yu have their powers restored? And now that the Iron Dimension is the only world that hasn't been conquered yet, how will they protect their world from being swallowed by the darkness?

Season 3, 4, & 5: This takes place in another dimension called Silver Dimension, where you can't eat chickens. They're actually sacred there, no lie. It's illegal to eat fried chicken, basically. No KFC or Church Chicken.

The war of the universe is finally over; good has prevailed and the order of the worlds has been restored. However, that doesn't mean the worlds are at peace.

A new story is about to unfold in the Silver Dimension.

Guan Yu and Zhang Fei have been best friends since childhood, and together, they attended 23 schools that always expelled them for starting fights. On their first day at their 24th school, they get kicked out again and encounter Liu Bei, who proposes that they could become sworn brothers to enroll the world famous Dong Han Academy, a school exclusively for royalty. With Liu Bei being the one with royal blood and the boys' guardian and Zhang Fei paying their tuition, they are sure to enroll the school without problem.

But when Wang Da Dong, Wang Ya Se, Ding Xiao Yu and Xiu travel to the Silver Dimension for relaxation, Da Dong drops a penny that eventually causes a human-sized rock to fall down on Liu Bei at the exact moment the three boys swear their vows. As a person who honors his promises, Guan Yu attempts to commit suicide because their vows include them all dying on the same day, but Zhang Fei stops him. When they realize that Xiu and Liu Bei look exactly alike (because they are each other's alternate counterparts), Xiu is forced to temporarily impersonate Liu Bei until he recovers.

Though they enroll the school without a hitch, problems won't stop coming as they must survive the school's traps and hostile invasions from many warring schools. Together, Guan Yu and Zhang Fei encounter Zhao Yun, Ma Chao and Huang Zhong, with whom they eventually become dubbed as the "Five Tiger Generals": the protectors of Dong Han Academy.

The Five Tiger Generals' bond gets tested when Guan Yu is forced to honor his agreement with Dong Zhuowhile his powers are subdued by evil. Xiu's real identity falls on several threads when problems arise. Huang Zhong reunites with his mother but were forced to separate because she is a member of the Huang Jin High School. Guan Yu and Lu Bu become demonized when they both learn Hao Cha Jing to neutralize the effects ofZhen Cha Jing. Lu Bu takes the path of evil and stands in opposition with Dong Zhuo and the Five Tiger Generals. Xiao Qiao and Da Qiao resolve their misunderstandings and finally reconcile. The love relationship between Xiu and Sun Shang Xiang gets tested when the real Liu Bei returns.

Principal Wang is finally back to Dong Han Academy, only to get killed by Dong Zhuo later. Xiu/Liu Bei's identity is at greater risk than ever. The Silver Dimension's timeline gradually catches up to the Three Kingdoms' history.^[2] Dong Zhuo claims control of the imperial court and wreaks havoc everywhere, prompting everyone to war against him. With the assistance of Zuo Ci, the Five Tiger Generals finally defeat Dong Zhuo and reclaim the Nationwide School Union from his hands.

However, he turns out to be a regular person and eventually, Yuan Shao is able to claim Dong Han Academy's landmark into his own. With four of five Tiger Generals gone and everyone forced to retreat to Jiang Dong, Cao Cao's power is weaker than ever.

With Dong Zhuo gone, a new age begins, and new problems. Yuan Shao takes the landmark of Dong Han Academy in his own hands, forcing the Five Tiger Generals, Xiu/Liu Bei and Cao Cao to find the one man who can save it: Zhuge Liang - the famous strategist. With old enemies gone and new characters come into the picture, a new battle will begin.

Season 6: Back at the Gold Dimension, 10 years from Season 1, supposedly....

Wang Da Dong is on his way to transporting Liu Bei to the Iron Dimension when a timequake sends them both into different places of time. Da Dong wakes up to find himself 10 years later in the Gold Dimension, where he and every known power-user of the last generations have gone missing. Worse, his powers have somehow disappeared.

He then infiltrates the new generation of the Ultimate Class to investigate the reason, but runs into trouble with the new leaders.

Season 7: This still takes place in Gold Dimension because it's a continuation of the previous season because in that ending it rewinded time because of a virus and stuff.....I'll explain later in the story you're about to read.

This season picks up where Season 2 left off. With the timeline reset and the KO ranking restored, we see the return of some familiar faces from Season 1.

Wang Da Dong joins Xiu as a member of inter-dimensional guards. When sudden spikes in fighting power propped up in Da Dong's old high school disrupting the KO ranking, he goes undercover to investigate... as a 28 year-old dropout repeating high school. His first order of business is to reestablish his authority inside the class of KO One. His behavior immediately clashes with the current leader, King. While the class looks on to see who would emerge victorious, the competition for leadership intensifies with new transfer students joining the fray.

Season 8: Takes place in many years at the Iron Dimension after the ending of the last season...basically a never-ending battle which causes people with battle point powers to not age for a long while....so who knows how long it's been. Heh. 

Xiong Ge starts a new life following the disappearance of her sons and ex-husband. She opens a hostel called The X-Dormitory, in which she treats her tenants like her family. When Room 206 mysteriously appears out of no where and out walks her ex-husband, she gets a terrible feeling in her gut that something bad is about to happen.
