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.
