Knights College

One day a young man named Argo, who had led a carefree life in a rural fishing village, receives a letter of recommendation from an unexpected place. It was from an elite educational institution known as the Knights' College. The reason for the recommendation of the son of a simple fisherman is the special ability to "mapify" asleep in him. So Argo goes to live at Knights College to learn how to use his ability.
In Knights College, all conversations and movements are done through card selection. Each time you get a new card, it unlocks a conversation, unlocks a different route, or increases your liking with a character. The more cards you have, the more places you can visit and the more you can talk.
