⚠️The characters 益, 荒 are left out above: we do not yet have a meaning for them that we are sure of, and we would rather show a gap than a guess.
These are the dictionary meanings of the characters, not a statement about why this particular name was chosen — that is the stablemaster’s business, and we do not guess at it. How ring names are put together →
