Mitsumete Knight is set in the fictional medieval country of Dolphan, where you play as a young man tasked with becoming a Holy Knight to defend against neighboring state Valpha. However, upon arrival, your focus shifts towards local girls, sparking an intriguing mix between training and romance.
The gameplay combines elements of both dating sims and RPGs, presenting a unique experience where your schedule determines the activities you undertake to win over your chosen girl. As you progress through various interactions, skills are gained, which in turn impact how impressed each girl will be by certain abilities. Alongside this, hit points accumulate, allowing for level progression akin to traditional RPGs. Battles with enemy knights from Valpha and other foes can occur at any time, with the outcome largely influenced by your prior training.
