In the World of Type-Moon, Starting as Morgan's Husband

As a Master who had traveled to this world, Ian wasn’t particularly familiar with Chaldea. But that didn’t matter—he possessed a unique ability that no other Master had: a simulator. This allowed him to leave his mark on history. —Although not in the most conventional ways. 【You became the husband of the Enchantress, but simultaneously had an affair with the Holy Knight King disguised as a man, causing chaos throughout Britain because of you.】 【You controlled Tamamo-no-Mae and, as her master, demonstrated to Minamoto no Raikou what it means to subdue demons physically, making the monsters of the Heian period steer clear of you.】 【You made Medusa lose her composure, with all of Greece echoing her desire to remove her blindfold the moment she reunites with you.】 【You are Jeanne d'Arc's soulmate, the only one who knows how to truly liberate and relax this usually reserved saint in every possible sense.】 Ian had to admit, this simulator that understood people so well was a perfect fit for him. Solving all problems in his favorite way. Everything was going well. Until one day, they appeared beside him as Servants. It was only then that Ian realized he had accumulated quite a number of romantic debts.
