A Korean mobile gacha RPG developed by NAT Games and published by Shanghai Yostar (JP) and Nexon (Global).
The game revolves around a player character, known simply as "sensei" (teacher), a person brought in to assist in running the city of Kivotos following the mysterious disappearance of the president of its General Student Council. The player must assist in solving local issues, managing students, and assisting various schools, while investigating the mystery behind why the GSC president left. Gameplay takes place in a 3D isometric view, but is largely automatic, with player input being limited to triggering "Skill Cards" that enable students' special abilities.
