Drill Shoujo Spiral Nami

Our lonely and bored guy decided to buy a maid doll robot. Since he can't afford a new doll, he ended up buying a prototype with a missing right arm. The store owner put in a drill arm as replacement. So, to get enough money to buy a normal arm for his maid, he let her work Monday to Friday to train her stats and earn some money. On Saturday and Sunday, he can take her to doll fights to win more money, or have fun with her if he bought parts necessary. If he defeat other dolls, they might like him too. This game is nice that even though you have one year, you can end the game early with most doll girls.
