I'm not denying that it's irregular, especially since it's the first successful attempt at mixing demonic and holy powers into one, I'm saying that it's still technically a subspecies. Regardless of its status or importance, it's a subspecies because it's not the original Balance Breaker. Also, it's not like everyone can get the same subspecies. Each one that is formed is unique to the personality of the wielder like with Jeanne's dragon and Kiba's dragon knights. There's also the fact that subspecies can also occur for Longinus. So, I can't see why it's not a subspecies when all the information provided by the series says otherwise.

And no, just because it was called irregular in the chapter it was introduced does not make it not a subspecies. That was only said because, at the time, something like that should have been impossible and only happened because God died. Just because no one else has achieved a similar phenomenon with their Balance Breaker does not mean that it's not a subspecies.
