I have run this game in the past.

I noticed BASARA 4 Sumeragi leaderboards has Any% so I submit my video as a new category.

Utage has a category for individual stages which you can post your runs of a specific stage, but all stages catergory would be nice since i run the all stage Speedrun for Utage (and other Basara games), and quick reminder that Utage Speedrun Board uses IGT (In Game Time) instead of RTA (Real Time Action)
