"Thunderous Slash"!
The heavy sword technique of the Rhine Tribe was quite famous throughout the Bimon Kingdom, with "Thunderous Slash" being one of the high-level sword skills. A Rhine swordsman enveloped in the sword's wheel could, like a saw blade, perform four consecutive somersaults in the air, endlessly slicing his opponent. Striking from the air, the robust Rhine swordsman could control multiple lines of attack, covering a vast area. Being hit by this powerful slash could shatter even a rock to pieces, let alone a person—Prince Richard clearly had the intent to kill!
Up until now, all Beamon involved in the brawl had shown restraint, as nobody wanted to create a bloodbath in the Royal Capital. Unexpectedly, the first to harbor killing intent was Prince Richard himself.
