Casio wasn't sure what the rank of his Demon Idol Secret Martial Art was. Because this set of secret martial arts was based on his physical body's re-development and transformation, normal martial artists wouldn't even be able to grasp the basics of the Demon Idol Secret Martial Art. For them, it was useless, with only its combat skills having any value.
However, to Casio, who was completely compatible with the Demon Idol Secret Martial Art, it was vastly superior to third-rate martial arts like the Wind Elephant Secret Martial Art, and second-rate ones like the Rainwater Secret Sword. It was absolutely top-tier. The Secret Martial Art that suits oneself is the best Martial Art.
Without a doubt.
Even if a top-tier Secret Martial Art was placed in front of him now and offered in exchange for the Demon Idol Secret Martial Arts, he absolutely wouldn't agree to it.
In the middle of the room, Casio gathered his thoughts again.
