@Anon Regulus' protection against projectiles is not absolute. Sairaorg got downed by Crimson Blaster, after all, which is surely weaker than Star Buster Star Blaster which has defeated gods. And Shooting Star's lack of control over his Longinus' power was the reason for his losses early on, and the reason he picked up the pace and started his winning streak until reaching the finals is due to overcoming that weakness.
