There were a couple hints indicating he was Irregular, but there's also a lot of hints that he's Allen. I personally still think he is even with the hints that suggest otherwise. This idea seems to be strengthened by Master of the Heavenly Yard, where Re_Birthday Truth has Allen singing it. We'll learn more in the novel but I certainly don't think it's about an unknown character, whatever is revealed.
