Vibrations
Rui had very specific ideas regarding what directions he wanted to explore.
The Yin-Yang Shield had earned his fascination and his awe.
Perhaps it was not the objectively best option that was at his disposal.
But it didn't matter. Even if there was an option out there that would have yielded a better return on investment, he had already decided that he was going to pursue this particular avenue.
"Vibrations…" he pondered out loud.
It was a phenomenon that he had long grown familiar with.
Many of his techniques were based on it in some way or another on vibrations.
His Mighty Roar Flash Blast technique was inherited from the G'ar'arkan Tribe to the Reverberating Lance that he had mastered from the database. He had also developed a large number of his own vibration techniques from scratch.
