Yaiba (Show by rock!!)

Yaiba is the bassist of ShinganCrimsonZ. He often speaks with an air of legend and a tone of grandeur, as if he were a musical samurai warrior. He always carries his bass called "Ryukenden," which is like a katana-shaped bass.

Yaiba is usually a rather serious but charismatic guy, always talking about legends. He feels loyalty and friendship towards his ShinganCrimsonZ bandmates (Crow, Aion, and Rom), with Aion being his best friend.
He always talks about music as if it were something legendary or grand; Yaiba loves theatricality, epicness, festivals, and legendary tales.

and hates creatures that want to take over music like dark monsters
When Yaiba has to fight something as a threat, he always draws his low katana, Ryukenden.
