Yami (in Japanese: 闇) is a worldwide organization of martial artists who use their skills to gain power and the main antagonists of the second half of the History's Strongest Disciple Kenichi series.

Yami was created after WWII to keep the old arts alive becuse many martial artists died during the war. It is divided into two divisions: the Hand-to-Hand Combat Division and the Weapons Division. Both Divisions normally work separately and are lead by two completely different units, but recently have joined forces to complete their goal of starting the "Eternal Setting Sun" and claiming the title of "Strongest in History". The leaders of the Hand-to-Hand Combat Division are The One Shadow Nine Fists and the leaders of the Weapons Division are the Hachiou Executioner Blade, both teams are considered to the strongest in there divisions, and overall equal in terms of manpower and skills. Yami is the opposite of Ryozanpaku: it has enough funds to become a nation of its own while Ryozanpaku veers on the edge of bankruptcy, but at the same time its members lack the emotional bonds with one another that is so often present amongst the members of Ryozanpaku.

It should be noted that because Yami's operations are (currently) mostly in Japan and its members are mostly Japanese, the organization mostly goes by the name "Yami". However, Christopher Eclair has called it by the name "L'Obscurité", meaning "The Darkness" in French, and then stating that the organization's name was "'Yami' in this country", referring to Japan and indicating that the organization may be known by other names synonymous with "darkness" depending on the country of operations.

Its members seem to anticipate an event known as the Eternal Setting Sun, which seemingly intends to create a Third World War so that their skills will not "rot away in these times of peace". Yami power had now became even stronger that the members of the One Shadow Nine Fists has a meeting with the Major of Japan.
