• You are the “Trainer” of Four Princesses – The setting of the story is a world where swords, magic, and “relics” of an ancient civilization exist. The mission of the protagonist, the battle and training expert known as the “Instructor Knight,” is to become the “trainer” of the four princesses of the four countries belonging to the “Relic Islands.” Guide the princesses properly, lead soldiers into battle as a commander, and fight together
• Praise, Scold, and Train the Princesses – The hero can guide the princesses in various situations, such as during conversations or in battle. By appropriately conducting two types of guidance—“praise” or “scold”—you can stimulate the growth of the princesses and grant them temporary stat increase effects, allowing you to advance battles with a greater advantage. Through sometimes praising, and sometimes scolding the princesses, raise them to maturity
• Command Soldiers and Defeat Enemy Armies – The player, as both the princesses and the protagonist, will lead their own platoon into battle, and fight alongside their soldiers while also wielding a weapon themselves, while aiming for the destruction of their enemies and the completion of their mission. This is a type of strategy action where both the player character and the commands issued to soldiers are the key to victory

The setting of the story is a world where swords, magic, and “relics” of an ancient civilization exist. You, the battle and training expert known as the “Instructor Knight,” receive a request to visit the four “Relic Islands.”

As an instructor, your mission is the guidance of the four princesses belonging to each power.

“The Kingdom of Alixern City,” a country of lush agriculture. “The Rust Magic Guild,” which has a strong desire for knowledge, but lacks moral value. The “Noble Business Alliance,” where “relics” are actively utilized. And the “North Amata Clan Federation,” where many demi-humans reside.

How will you teach and guide the princesses? Which princess’ battle will you oversee? What sort of conclusion awaits? Everything depends on the choices you make.

The story of “you” and the “four knight princesses” is about to begin.
