Too right, there’s something about characters how minor ones can play larger roles and be more important to the story. First, Basteya is yet another amazing character from the first appearance named right away. This Hyakuya Sect member was a ‘generic’ background scientist who thanks to his cunning and Jigenso weapon is now actually increasingly important.
Playing too large a role now to remain unnamed so also hope we get his name. Having said that he is a very effective secret agent so just as likely the name will remain ever a secret XD Black demon weapon holder as well right under everyone’s nose!
Also for all his tact and skill there was simply a larger monster around in Ferid so if anything should hopefully get some more insights on this agent, and a particularly skilful black demon!
