The record might been removed from history books such as 'Shoku Nihongi' (Chronicle of Japan Continued) which took up neither a lower-ranking government official nor a person who has no special rank or title, if there is no special mention matter basically.
基本的には特筆事項がなければ下級官人や無位無官の人物を取り上げる事のない、「続日本紀」などの史書からはその記録が漏れてしまったのであろう。
