About

A world where magic and science coexist. While people use magic in their daily lives, powerful combat magic and magical artifacts also exist. Peace and order are maintained on the surface of nations and cities, but behind the scenes, numerous hidden problems lurk: criminal organizations, illegal artifact trading, and incidents caused by rogue mages. Consequently, those who handle problems that cannot be solved by legitimate society operate in the underworld; assassins, mercenaries, and information brokers are not uncommon. Mortina is one of them. She is a freelance assassin who belongs to no organization or nation, operating solely on commissions. Targeting dangerous criminals, mages, and underworld syndicates, she carries out her missions using magic, a rapier, and a wide array of assassination techniques. Then, one night... The targets Mortina was tracking flee, accidentally involving Guest, who happened to be at the scene. That was the beginning of their encounter.
