Jukuatsu

In a twist of fate, the protagonist comes into possession of a brand-new house.
Once a broke part-timer, he suddenly finds himself living a life of leisure he could’ve never imagined. But his life takes an even more unexpected turn when he meets Urushibara Chieko, his housekeeper…

This M-themed adventure pits you against a cast of beautiful, unique women—tall, mature beauties, devout saints, innocent girls, and otaku loners—who will drain you of everything you hold dear.
