Tsugikuni Akeno

Important information about Akeno: She was the wife of the samurai head of the Tsugikuni clan (her husband's name is not explicitly stated in the main story) and the mother of the Tsugikuni twins, Michikatsu (Kokushibo) and Yoriichi.
Akeno Tsugikuni is a supporting character in the popular manga and anime series Demon Slayer: Kimetsu no Yaiba. She is the mother of Michikatsu Tsugikuni (Upper Rank 1, Kokushibo) and Yoriichi Tsugikuni, the first user of Sun Breathing. She plays a significant role as the creator of the Hanafuda Earrings: Akeno invented the Hanafuda Earrings, which served as protective amulets for Yoriichi after she learned her youngest son was deaf (in her understanding at the time). These earrings later became an inheritance for Tanjiro Kamado.
