Yamada Asaemon Sagiri traveled to Shinzenkyo to guard Gabimaru. She holds the 12th rank in the Test Sword School. She is the only female Yamada Asaemon with long black hair pulled back in a ponytail. However, because she is a woman, she is often discriminated against in the Jigokuraku anime even by those who also call themselves Yamada Asaemon, such as Genji and Seisei.
She is self-conscious about the fact that she aspires to be a swordswoman like her father, but has not yet given up her fear of killing people, but after meeting Gabimaru, she began to think that what she needs is the determination to take on the lives of those she has killed. She believes in the "middle way", which is a combination of feminine and masculine, strength and weakness.
