The top character 姉 is a Japanese specific character for "elder sister". Its equivalent in Chinese are 姊 and 姐.
The bottom character 妹 means "younger sister". If the order of two horizontal stokes in 未 partical are reversed and changed the character to 妺, it would mean "wife of the last ruler of the Xia dynasty".
Both characters are somewhat recognizable, but I am astonished by the mangled left partial 女.
