The Case of My Admired Older Sister Being an Unexpectedly Ultra-Lewd Bitch Maid! I have an older childhood friend who is much older than me. Her name is Reika. She was excellent in her studies, beautiful in appearance, truly a flower on a high peak, and her family was also wealthy, but her parents disappeared after incurring a large amount of debt. Reika-neechan became the exclusive maid of our house... However, after living together, I noticed that my sister was extremely vulgar and lewd... What on earth is going to happen to me!?
