Dead or Alive 1 - Kasumi

A massive corporation known as DOATEC (Dead or Alive Tournament Executive Committee) host a fighting competition called the Dead or Alive World Combat Championship, where fighters from all over the world can compete for the title as champion and a vast amount of money. A runaway kunoichi known as Kasumi enters the Dead or Alive tournament to seek revenge against her uncle Raidou, who was responsible for crippling her brother Hayate.

Kasumi's brother Hayate was next in line to succeed their father Shiden as the 18th leader of the Mugen Tenshin Ninja Clan. After Hayate was crippled, Shiden was left bitter from what Raidou did to his son and he refused to discuss the details surrounding the attack. Shiden ordered his daughter Kasumi to take her brother's place as the next leader of their clan. Kasumi abandoned her village when she learned that her evil uncle was her brother's attacker and she tracks him down to the Dead or Alive tournament where she enters to defeat him.

Kasumi eventually defeats and kills Raidou, but her decision to leave her village without permission violates the strict laws of the ninja society and is punishable by death. As a result, she becomes a hunted fugitive.

Dead or Alive (Japanese: デッド オア アライブ, Hepburn: Deddo oa Araibu) (DOA) is a media franchise based on a fighting video game series produced by Tecmo and developed by Team Ninja. It is primarily composed of fast-paced 3D fighting games that begun with the original Dead or Alive in 1996. The series received critical acclaim with the sequels Dead or Alive 2 in 1999 and Dead or Alive 3 in 2001 which are considered landmark titles. DOA is the creation of Tomonobu Itagaki, who has since left the company and is no longer working on the series, which continues without him.

The plot of the series revolves around the events of the Dead or Alive Tournament where fighters from across the globe participate in and is hosted by the Dead or Alive Tournament Executive Committee (DOATEC). The conflict between the ninja competitors and DOATEC's personnel serves as the main focus of the series.

Dead or Alive has been well praised for its impressive fighting system, graphics, and interactive environments. The franchise consists of six main fighting games, numerous updates and spinoffs. In addition to its fast-paced and countering-based play system, the franchise is also known for its female characters. This aspect of the series' popularity led to the creation of the spin-off game Dead or Alive Xtreme Beach Volleyball and its sequels, where the females and their sex appeal play a more focal role than it does in the core Dead or Alive series. A live-action film adaptation DOA: Dead or Alive was released in 2006.
