Kuwashihime no mikoto (細媛命)
In the main text of "Nihonshoki" (Chronicles of Japan), she is mentioned as the Empress, and she was a daughter of Shiki no agatanonushi Ome. In "Kojiki" (The Records of Ancient Matters), the Empress was Hosohime, a daughter of Ome, who was an ancestor of Tochi no agatanonushi.
On the other hand, the first addendum to the Nihonshoki mentions the Empress was Kasuganochichihayayamakahime. However, the second addendum describes the Empress as Mashitahime, who was an ancestor of Tochi no agatanonushi and others.
