Senka Yorozu

Acting as the dedicated landlady of the Yorozuyo boarding house, this spirited woman oversees the living arrangements for residents like Kazuma and Ayumu. While she maintains a firm grip on her property, she is particularly sensitive about her age and will take offense if anyone refers to her as "Oba-san." Instead, she insists on being addressed with the more youthful and respectful title of "Nee-san" to preserve her youthful image.
