On the 20th floor of the Tower, the "Regulars" who have been permitted to enter have to undertake arduous and extremely expensive tests to rank up. Most abandon hope and choose to stay where they are—but not Ja Wangnan. Wangnan is determined to reach the top and become the king of the Tower. However, he is weak and has repeatedly failed the exam, with debt collectors tailing him. In desperation, he attempts the exam one more time, only to encounter a mysterious and powerful individual: Jyu Viole Grace, a member of the crime syndicate FUG. Cursing his rotten luck, Wangnan has no choice but to form alliances with strong people, including Viole—who still refuses to be part of any team. Amid a dire situation, Wangnan must find a way to change Viole's mind to finally advance past the 20th floor, or he will never get a chance to build his legacy.

Golgo 13 is not his real name. Then again, neither is Duke Togo, Tadashi Togo, or any number of the aliases he goes by. A man of mystery, not even the world's most prominent intelligence agencies can determine who Golgo really is, or just where he came from. But all agree that his skills are nothing short of legendary. Armed with a custom M16, Golgo is willing to take any job for any agency, from the FBI to the KGB. He has completed every contract he has ever taken and will work for anyone who can meet his price. He is both the greatest weapon and the greatest threat to any nation; no one is safe once they are in Golgo’s sights.
