Koinosu ☆ Ichacolize is all about building a ‘love nest’ where you can be lovey-dovey with your ideal girlfriend. After choosing your heroine and deciding on your name (default is Masakage) at the beginning, the game branches off into three separate routes which all take place in the same setting (your apartment), although with different story backgrounds. Ichika is a servile waitress who catches your eye at a café that you frequent. Sachi is a petite girl who you used to play with and with whom you were entrusted on days when she attends a cram school nearby. Natsume is the imouto of your next door neighbour who temporarily lives there when her older sister studies abroad.
