New champion in the ''Project: Overdrive'' video?

Ok this champ is everywhere in the new ''project: overdrive'' video... and i dont know if you remember but ''bard: mountain'' ''ekko: seconds'' there is always a word then '':'' and another word. This time it's not that different right? Well anyway, who is this guy in the videos? It seems to be an orcish samuraï with 2 swords... He is also in the beginning of the video, when zed isnt even there, and we can never really see him... his background is always this destroyed chinese village with the leaves falling, and it seems to be related to yi's past. Also he appears 4 times and i don't thing Rito make things randomly... so idk. I really dont... but there is a mystery in this video.
