Not a speedrun, but instead a Bounty Board Quest from the Rain server.
Because this is a BBQ, my gear is limited to not be zenith level and certain skills like Solid Determination are banned, creating extra challenge.
Guanzorumu is a pretty basic fight compared to other endgame frontier monsters, but still has an interesting moveset to play around, particularly in its enraged second phase where everything becomes so fast.
Hope you enjoy the video!
