"Hyper Operative Baking and Ripping Technology - SiIvaGunner: King for Another Day Tournament" is a high quality rip of "Hyper Operative Baking and Ripping Technology" from SiIvaGunner: King for Another Day Tournament.
This is a reveal trailer for the competitor HOBaRT.
Like all of the reveal trailers, it begins with the "What's This!?" jingle and animation. It then fades into video footage of a Hobart mixer. The video then fades to white, and the song "Hobart Drive" by Jerry Galeries starts playing as various shots of the mixer are edited in time with the music.
HOBaRT's name and character art appear onscreen, followed by the usual King for Another Day outro.
