The ring name is written 信正道. Taken character by character:
| 正 | correct, upright |
| 道 | road, the way |
⚠️The character 信 is left out above: we do not yet have a meaning for it 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 →
