This is the world of TEKKEN (Bandai Namco), and this is the eighth Tekken tournament. Heihachi Mishima as you had heard of by now "died" or went missing as they say (but of course, we all know he is hard to kill, so why even bother now anyways?). Anyways; the world has not been the same place ever since, with war raging between the side of Jin Kazama and Kazuya Mishima still on-going, Heihachi Mishima was saved and rescued by The Tekken Monks, then they trained him there, he fought his evil side and all that, BUT EVEN THEN STILL... he came back somehow way more evil than before and decimated them the entirety of The Tekken Monks and also defeated Lidia Sobieska, Eddy Gordo and Yoshimitsu altogether there all at once while holding on his own with seemingly such barely any effort.

But then... you are, and got sucked straight up into this world all of an sudden. So what to even do in this world, pretty much as of right now currently, eh? Choose your choices carefully and all of that.
