Kouda Saya is an ordinary Kuchinari High School student, except for her "allergy" to good-looking guys. However, with the help of her childhood friend, she aims to win the “Kuchi High Prince Collection”, a school competition all about ranking guys' looks. The game features customization, with the player being able to change the heroes' hair styles, clothing, hats, glasses and accessories. These are called "coordinate items" and are available to collect throughout the game. The player can also change the heroes' personalities. Each love interest has 5 different personality types, such as Ore-sama, Tsundere, etc. There are 15 types of happy ends in total. Event graphics differ according to the hero’s look and different kinds of events take place depending on his personality! Collected coordinate items and personalities can be carried over to the next playthrough.
