Yuri Hoshigaoka

She is a 24-year-old female teacher who serves as the assistant homeroom teacher for Nobunaga Oda's class. She is often praised by those around her for her voluptuous chest. However, ever since the appearance of Jitokuin, she has become unable to feel at ease unless her nipples are regularly sucked. Because Jitokuin rarely appears in public and Nobunaga Oda frequently makes inappropriate comments as a man, she greatly detests the current situation.

Jitokuin is an ancestor of Yuri Hoshigaoka and appears when she is touched. She speaks in a Kansai dialect and is known for her airheaded personality. In the past, she served as the wet nurse for Nobutada Oda, and since she enjoyed having her breasts sucked, there is a lingering attachment toward Nobunaga Oda. Furthermore, it is said that when she became a concubine to Nobunaga Oda, she did not hold any special feelings for him. After having her breasts sucked by Nobushige, Nobutada's soul was able to find peace.
