Just found this guy's entry for the first time ever. He's part of Peak A Soul+ by the
credits of Arc the Lad: Twilight of the Spirits.
Given that, I strongly suspect this is the real name of
Takago Azuma.
Incidentally, I wonder if our reading of
Inazuma Higashi is correct or if that should be Inazuma Azuma. (Inazuma & Takago are listed separately on Peak A Soul+'s creators page, so I don't think they're the same person.)
