The PlayStation Vita (PS Vita, or Vita) is a handheld game console developed and marketed by Sony Interactive Entertainment. It was first released in Japan on December 17, 2011, and in North America, Europe, and other international territories beginning on February 22, 2012. The console is the successor to the PlayStation Portable, and a part of the PlayStation brand of gaming devices; as part of the eighth generation of video game consoles, it primarily competed with the Nintendo 3DS. The original model of the handheld includes a 5-inch (130 mm) OLED multi-touch capacitive touchscreen, two analog joysticks, and front and shoulder push-button input, and supports Bluetooth, Wi-Fi, and optional 3G. The Vita features a quad-core ARM Cortex-A9 MPCore CPU and a quad-core SGX543MP GPU. The PS Vita 2000 series, a revised version of the system, was released across 2013 and 2014. It has all of the same features with a slightly smaller size, extended battery life, and an LCD panel instead of an OLED. Sony released the PlayStation TV, a short-lived, re-purposed version of the Vita that uses a television screen like a home video game console, discontinued at the end of 2015. The Vita's design was intended to meld the experience of big-budget, dedicated video game platforms with the then up-and-coming trend of mobile gaming as seen on smart phones and tablets. However, in the year after the device's successful launch, sales of the hardware and its bigger budget games stalled, threatening to end its lifespan. A concentrated effort to attract smaller independent developers in the West, combined with strong support from mid-level Japanese companies, helped keep the platform afloat. Though this led to less diversity in its game library, it strengthened support in JRPGs, visual novels, and Western-developed indie games. This built moderate sales in Japan and a smaller yet passionate userbase in the West. Though Sony has not released exact sales figures, estimates are around 15 to 16 million units. In the platform's later years, Sony promoted the PlayStation Vita's ability to work in conjunction with its other gaming products, such as Remote Play of PlayStation 4 games, similar to the Wii U's function of Off-TV Play. The platform stalled in 2017 upon the release of the Nintendo Switch, and was completely discontinued in 2019. The system is regarded as a commercial failure in the video game industry, and was significantly outsold by the Nintendo 3DS. No direct successor was released by Sony, though in 2023, a similar remote play accessory, PlayStation Portal, was announced for release by the end of the year for the PlayStation 5.
As Kei Ikushima reaches the finals of the Sentoki tournament, Ranzou Kihara, who was watching over the tournament, would unleash K-001, a clone created in Kei's image and infused with all of the fight data collected by Orion, upon her. After a grueling battle, Kei was able to defeat the clone and win the match, until Ranzou, not liking the results, decided to restart the match right there and then. As the match got restarted, K-001 proceeded to attack the battered and exhausted Kei in cold blood, delivering vicious blows and strikes, which incapacitated her. She was about to be killed when Shin intervened and fought with the clone. He was eventually able to defeat K-001, but Kei barely survived after all of the injuries she suffered, and was sent to the hospital shortly afterwards. Meanwhile, outside the arena, a mysterious man who goes by the name of "Nixon" watches the entireity of the tournament through some of the TVs displayed on a surplus window. All alone on the streets, Nixon has no memory about his past, living his current life as a vagrant, walking the streets of Tokyo aimlessly and occasionally fighting in underground pit fights as his only livelihood. However, despite his amnesia, he seems to recognize the face of Ranzou Kihara. He dosen't understand it either. He just felt something... oddly familiar about him. It was as if Nixon's mind was drawn to this man, for reasons that aren't clear to himself at all. A rising urge builds up within him: a strong desire to meet Ranzou Kihara himself in order to make sense of his amnesiac mind. Almost a year after the last tournament, Orion would eventually announce the fourth Sentoki: Global Martial Arts tournament. Upon hearing the news, Nixon wasted no time and decided to enter the tournament, his mind dead set on meeting Ranzou, thinking he has all the answers to his past.
