In the World of Type-moon, Start by Becoming Morgan's Husband!

As a master who traveled through time, Ian was not so familiar with Chaldea.

But it didn't matter, he had a special ability that other masters didn't have - that was the simulator.

This allowed him to leave his own footprints in history.

- Although it was not normal.

[You became the husband of the demon concubine, but at the same time you cheated on the Holy Knight King disguised as a man, and Britain was in a mess because of you. ]

[You controlled Tamamonomae, and as a master, you let Minamoto no Raikou witness what physical demon exorcism was. The ghosts of the Heian era avoided you. ]

[You made Medusa lose her mind, and the whole of Greece echoed her statement that she would take off her blindfold when she met you again. ]

[You are Jeanne's soul mate, and only you know how to make this saint who is usually very restrained achieve liberation and relaxation in various senses. ]

Ian had to say that this simulator that understands people's hearts is really suitable for him.

Solve all problems in his favorite way.

Everything is fine.

Until one day, when they came to him as servants.

Ian realized that he had caused a lot of romantic debts.
