True but lets not forget, Yachiru; name non-withstanding, had been seen by others for years and years on end. Plus the only reason nobody saw her when Zaraki's Bankai activated was because they were all too distracted by the enemy, But this explanation kinda drives the point of the matter home. Plus lets not forget names of a zanpakto tend to change when Shikai transitions into Bankai; again the name is non-withstanding, since we don't know either her real name nor the name of Kenpachi's Bankai.
