In Knights College, all conversations and movements are performed using a card selection. Each time you receive a new card, it opens a dialogue, opens a different route or increases your liking for the character. One day, Argo, a young man leading a leisurely life in a fishing village in the countryside, receives a letter of recommendation from the Knights College of his dreams. Not knowing why he was recommended, he enrolls and spends days with his fellow knights. Argo will learn a lot from the instructor. Argo trains swords and weapons. At the end of the day you can take a bath with your favorite character. Knight cadets will enjoy various events, such as room exchanges.
